Need help with Programming.
Input:
Write a Java inventory application program that will accept the following input values from the user:
a. An inventory item number consisting of two upper-case letters followed by three numbers (eg. AB123)
b. An inventory item description.
c. An inventory unit price (2 decimals).
d. An item quantity-on-hand (no decimals).
Use the TextIO.class to accept the values from the user.
Processing:
The input must be validated as follows:
Item number - must be not more than 6 characters in length. Then, of those six characters, the first two must be letters only, followed by a dash (-) and then three numbers. Eg. AB-456.
Inventory item description � must contain a value and be less than or equal to 20 characters in length.
Unit price � between 0 and 5,000.00 inclusive.
Quantity-on-hand � between 0 and 500 inclusive.
The letters of the item number must be converted to upper-case for display purposes.
Count the number of inventory transactions entered.
Accumulate the calculated inventory cost of each item.
Your program will contain six error messages as follows:
**ERROR01** - Item number must be five characters
**ERROR02** - Item number must start with 2 letters
**ERROR03** - Item number must be numeric in last 3 positions
**ERROR04** - Item description is required and must be max 20 chars
**ERROR05** - Unit price must be between 0 and 5,000.00
**ERROR06** - Quantity on hand must be between 0 and 500
Note: there is no �persistent� storage of the data in this program. In other words, once the new data has been entered, the program �forgets� the old data. We will learn how to keep the data in memory in a later assignment.
Output:
After each transaction is entered, display the results to the user (as in the previous assignment). Prompt the user for additional inventory transactions after the information is displayed.
If there are no more transactions to enter, display the number of inventory transactions entered during the session as well as the total cost of the inventory items processed. Your output must match that shown in the example screen shots shown on the next page.
Please E-mail me back the answer.
I would suggest,
- Make a serious attempt yourself. We may be will to help you learn but we are not going to help someone cheat in your assignments.
- After making a serious attempt ask a specific question on "New To Java" as this forum is for beginners. Be ready to provide the code as an example of your problem. Make sure the code at least compiles or you will not be taken seriously. (Unless this is your problem)

Attached is my program for inner join
Kindly Help
Thanks SuHi Su K
You May use key fields , Foreign keys for joining , Here
SELECT SBOOK~BOOKID SBOOK~CUSTOMID SBOOK~CLASS
SCUSTOM~ID SCUSTOM~NAME FROM SFILGHT
INNER JOIN SBOOK ON SBOOK~CARRID EQ SFILGHT~CARRID

Rookie needs help with program!!
Hi everyone,
I am new to JAVA programming and am trying to figure out my first progam. Any suggestions? Here's what I have to come up with...
This program will test your ability to code a loop function and some work with the strings methods.
INPUT
A SENTENCE OF UNKNOWN LENGTH.
OUTPUT
THE NUMBER OF WORDS IN THE SENTENCE AND EACH WORD ON A SEPARATE LINE. Two spaces are not a word; "a" is a word.
HINT
Use a loop until the end of the sentence and count each word that is removed from the front of the sentence (one at a time). Each time the sentence should be shortened.
I know I need to use a string method...Here's what I have so far...
public class jmstr
public static void main (String[ ] args)
System.out.println ("Please enter a sentence starting with some spaces ");
inputline = SavitchIn.readLine ( ) ;
System.out.println (inputline);
I'm not really sure what to do next....?
Any help would be appreciated!

}If you're looking to use a JTextArea as a console you can use these two classes
you are free to use and modify these classes but please do not change the package or take credit for it as your own work.

I need help with programs from my MacBookAir.
Hello. I've intalled programs on my MacbookAit that I don't need anymore and I have no idea how to remove them from my laptop. I've been a PC user and I knew there how to remove them but here I just don't know. I know that dragging them to the trash won't work. I want to remove them and free the space that is taking. I hope you guys can help me with this. Thank you Very Much!!!
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper 2.0.1
AppDelete 3.2.6
Automaton 1.50
Hazel
AppCleaner 2.1.0
CleanApp
iTrash 1.8.2
Amnesia
Uninstaller 1.15.1
Spring Cleaning 11.0.1
Look for them at VersionTracker or MacUpdate.
For more information visit The XLab FAQs and read the FAQ on removing software. -
Beginner needs help with programming assignment
So I have been working on it and it is reading everything and posting everything to the output file, but it looks like this
MonthlyRainfall(cm)
Average: 3.66
January 7.29, above averageApril3.55, below averageNovember0.15, below average
When instead it should look like this. Don't know what I need to do to get it to work like this. If I have to much regarding the IF Else statements or I just don't have it laid out right. Any help is appreciated. Thanks.

ok. so i've started a project which is based upon the ArrayList class. The first part asks me to generate 30 random numbers between 1-100 and storing these numbers in an ArrayList. I've successfully completed this part by the use of the Wrapper Class Integer.. blah blah blah.
Now, the second part asks me to find the minimum value stored in this ArrayList without sorting it. I've been having major problems solving this part. I've tried the compareTo method, lots of for loops, linear searches, storing a bunch of private data.... but i can't seem to get the minimum value.
HELP!
import java.util.*;

System.out.println(theList);

for(int i = 1; i < list.size(); i++)

}heres what u wanna do, i had this same problem once
int minval = 999;
int minval;
for(int v=0;v<=29;v++)
if(whateveryounamedyourarraylist.get(v)<minval)
minval=whateveryounamedyourarraylist.get(v);
System.out.println(minval);think thats right hope it helpsIt's safer to do this:
ArrayList list = new ArrayList();
int min = (Integer) list.get(0);
for (int i = 1; i < list.size(); i++) {
if ((Integer) list.get(i) < min) {
min = (Integer) list.get(i);
}and w/ new syntax:
ArrayList<Integer> list = new ArrayList<Integer>();
int min = list.get(0);
for (Integer i : list) {
if (i < min) {
min = i;
}If you ever run across a case where all the values are greater than 999
(yes i know this won't happen in this case but if you change the random number range,
this won't always work), then min will be 999 which wouldn't even be a value in the List. -

}the only problem now is about how it should display the right info about the person whenever i click its name on the list.. something about file reading or something, i just cant figure it out.
and also about how to make it scroll once it exceeds the list.. i cant make it work, maybe something about wrong declaration..
thanks in advance..
Edited by: syder on Mar 14, 2008 2:26 AMLike said before, do one thing at a time. At startup, something like:
//put all the content in a list
ArrayList<String> lines = new ArrayList<String>();
while(String line=rand.readLine()!=null) {
lines.add(line);
}If you follow the good advice to create a class to encapsulate the entries, you could populate a list of such entries like this:
static final int ENTRY_SIZE = 3;//you have 3 fields now, better to have a constant if that changes
ArrayList<Entry> entries = new ArrayList<Entry>();
for(int i=0; i<lines.size(); i+=ENTRY_SIZE) {
Entry entry = new Entry(lines.get(i), lines.get(i+1), lines.get(i+2);
entries.add(newEntry);
}You could also do both of the above in one run, but I think you will understand better what's happening if you do one thing at a time.
If you don't want to put the entries in an encapsulating class, you can still access this without looping:
int listStartIdx = <desired_entry_index>*ENTRY_SIZE;
String att1 = lines.get(listStartIdx).substring(1);
String att2 = lines.get(listStartIdx+1).substring(1);
String att3 = lines.get(listStartIdx+2).substring(1); -
Need help with a rudimentary program
I'm sort of new at this so i need help with a few things... I'm making a program to compile wages and i need answers with three things: a.) what are the error messages im getting meaning? b.) How can i calculate the state tax as 2% of my gross pay with the first $200 excluded and c.) how can i calculate the local tax as a flat $10 with $2 deducted for each dependant. any help is appreciated
Here is what i have so far:
public class WagesAsign1
public static void main(String[] args)
int depend=4;
double hrsWork=40;
double payRate=15;
double grossPay;
grossPay=payRate*hrsWork;
double statePaid;
double stateTax=2.0;
statePaid=grossPay*(stateTax/100);
double localPaid;
double localTax=10.0;
localPaid=grossPay*(localTax/100);
double fedPaid;
double fedTax=10.0;
double taxIncome;
fedPaid=taxIncome*(fedTax/100);
taxIncome=grossPay-(statePaid+localPaid);
double takeHome;
System.out.println("Assignment 1 Matt Foraker\n");
System.out.println("Hours worked="+hrsWork+" Pay rate $"+payRate+" per/hour dependants: "+depend);
System.out.println("Gross Pay $"+grossPay+"\nState tax paid $"+statePaid+"\nLocal tax paid $"+localPaid+"\nFederal tax paid $"+fedPaid);
System.out.println("You take home a total of $"+takeHome);
and these are the error messages so far:
WagesAsign1.java:23: variable taxIncome might not have been initialized
fedPaid=taxIncome*(fedTax/100);
^
WagesAsign1.java:29: variable takeHome might not have been initialized
System.out.println("You take home a total of $"+takeHome);
^edit: figured it out... please delete post

Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
Sorry for the length. Thanks for any help you can give.The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
private static GraphicsConfiguration gConfig;
private static Dimension compSize = new Dimension(80, 22);
private static Image image = null;
public static Image getImage(Class objectClass)
if (gConfig == null)
GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
gConfig = gDevice.getDefaultConfiguration();
image = gConfig.createCompatibleImage(compSize.width, compSize.height);
JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
jc.setSize(compSize);
Graphics g = image.getGraphics();
g.setColor(Color.LIGHT_GRAY);
g.fillRect(0, 0, compSize.width, compSize.height);
g.setColor(Color.BLACK);
jc.paint(g);
return image;
}And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
private static DragSource dragSource = DragSource.getDefaultDragSource();
private static DragGestureListener dgl = new DragMoveGestureListener();
private static TransferHandler th = new ObjectTransferHandler();
private Class compClass;
private Image image;
Dragable(Class compClass)
this.compClass = compClass;
image = JComponentImage.getImage(compClass);
setIcon(new ImageIcon(image));
setTransferHandler(th);
dragSource.createDefaultDragGestureRecognizer(this,
DnDConstants.ACTION_COPY,
dgl);
public Class getCompClass()
return compClass;
}Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
public static Object instantiate(Class objectClass)
Object o = null;
try
o = objectClass.newInstance();
catch (Exception e)
System.out.println("ObjectFactory#instantiate: " + e);
String name = objectClass.getName();
int lastDot = name.lastIndexOf('.');
name = name.substring(lastDot + 1);
if (o instanceof JLabel)
((JLabel)o).setText(name);
if (o instanceof JButton)
((JButton)o).setText(name);
if (o instanceof JTextComponent)
((JTextComponent)o).setText(name);
return o;
}Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
private static DataFlavor df;
* Constructor for ObjectTransferHandler.
public ObjectTransferHandler() {
super();
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
Debug.trace(e.toString());
public Transferable createTransferable(JComponent jC) {
Transferable t = null;
try {
t = new ObjectTransferable(((Dragable) jC).getCompClass());
} catch (Exception e) {

return t;
public int getSourceActions(JComponent c) {

public boolean canImport(JComponent comp, DataFlavor[] flavors) {

return true;
return false;
public boolean importData(JComponent comp, Transferable t) {
JComponent c = null;
try {
c = (JComponent) t.getTransferData(df);
} catch (Exception e) {
Debug.trace(e.toString());
comp.add(c);
comp.validate();
return true;
public class ObjectTransferable implements Transferable {
private static DataFlavor df = null;
private Class objectClass;
ObjectTransferable(Class objectClass) {
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
System.out.println("ObjectTransferable: " + e);
this.objectClass = objectClass;
* @see java.awt.datatransfer.Transferable#getTransferDataFlavors()
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[] { df };

* @see java.awt.datatransfer.Transferable#getTransferData(DataFlavor)
public Object getTransferData(DataFlavor arg0)
throws UnsupportedFlavorException, IOException {
return ObjectFactory.instantiate(objectClass);
}And of course the test class:public class DragAndDropTest extends JFrame
JPanel leftPanel = new JPanel();
JPanel rightPanel = new JPanel();
Container contentPane = getContentPane();
Dragable dragableJLabel;
Dragable dragableJButton;
Dragable dragableJTextField;
Dragable dragableJTextArea;
* Constructor DragAndDropTest.
* @param title
public DragAndDropTest(String title)
super(title);
dragableJLabel = new Dragable(JLabel.class);
dragableJButton = new Dragable(JButton.class);
dragableJTextField = new Dragable(JTextField.class);
dragableJTextArea = new Dragable(JTextArea.class);
leftPanel.setBorder(new EtchedBorder());
BoxLayout boxLay = new BoxLayout(leftPanel, BoxLayout.Y_AXIS);
leftPanel.setLayout(boxLay);
leftPanel.add(dragableJLabel);
leftPanel.add(dragableJButton);
leftPanel.add(dragableJTextField);
leftPanel.add(dragableJTextArea);
rightPanel.setPreferredSize(new Dimension(500,500));
rightPanel.setBorder(new EtchedBorder());
rightPanel.setTransferHandler(new ObjectTransferHandler());
contentPane.setLayout(new BorderLayout());
contentPane.add(leftPanel, "West");
contentPane.add(rightPanel, "Center");
public static void main(String[] args)
JFrame frame = new DragAndDropTest("Drag and Drop Test");
frame.pack();
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setVisible(true);
}I wrote this code some time ago, so it won't be perfect but hopefully will give you some good ideas.

Need help with a activation code for Adobe Acrobat X Standard for my PC, Don't have older Version of Adobe Acrobat 9, 8 or 7.
You don't need to install the older version, you only need the serial number from your original purchase. If you don't have them to hand, did you register? If so, they should be in your Adobe account. If not you really need to contact Adobe, though it isn't clear they will be able to do anything without some proof of purchase etc.

Need help with a currently "in-use" form we want to switch to Adobes hosting service
Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")
Thank You,

VinylCouture
Phenix City, Alabama 36869Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.
