Help with Inventory Program Buttons & images
I'm supposed to have buttons that move between the items in my program individually showing them one by one and also going to the first item when the last one is reached and vice versa, but I cannot get the buttons to to show even show up. I'm also having problems getting any type of image to show up. Any help on this would be appreciated.
My code is below

The program does work because I can get the content of my array to show in a GUI the only problem is the buttons aren't showing up in the GUI which is what I'm having a problem with. I also tried adding the panel to the frame but it didn't do any good either so maybe I'm not doing it right although when I compile I get 0 errors. What's the link to the swing tutorial?
JTextArea textArea = new JTextArea();
for (int a = 0; a < products.length; a++)
textArea.append(products[a]+"\n");
textArea.append("\nTotal value of the inventory is "+new java.text.DecimalFormat("$0.00").format(CalculateInventory(products))+"\n\n");
JButton prevBtn = new JButton("Previous");
prevBtn.setEnabled(false);
JButton nextBtn = new JButton("Next");
JPanel panel1 = new JPanel(new GridLayout(1,2));
panel1.add(prevBtn); panel1.add(nextBtn);
JFrame frame = new JFrame();
frame.getContentPane().add(new JScrollPane(textArea));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Need help with inventory program!!! someone please help me!!!
Ok I have to write this inventory program for one of my classes.
For part one i needed to Create a product class that holds the item number, the name of product, the number of units in stock, and the price of each unit.
Then create a java application that displays all of the above info plus the total value of the inventory. I have done this so far with success.
For part two i needed to modify the program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time including the item number, the name of the product, the number of units in stock, the price per unit, and the value of the inventory of that product. In addition, the output should display the value of the entire inventory.
so create a method to calculate the value of the entire inventory.(i did this)
and create another method to sort the array items by the name of the product. ( i did this)
The program compiles and runs fine except it is not doing anything from part two. It just does the same thing that it did when i wrote part one.
Does anyone know why or what i need to do to my code.
Here is my code.
import java.util.Scanner; // program uses class Scanner
import java.util.Arrays;
class ProductList
Product[] products = new Product[100]; // an array of 100 pruducts

Edited by: jay1981 on Mar 16, 2008 2:07 PMYou will get more help if your code is formatted better:
* Only post code that is already formatted correctly including indentations.
* Get rid of all those comments cluttering up your code.
* Make sure your posted code compiles without need for any changes. Yours doesn't at present. Where is the ProductInfo class?
Again, you want it easy for a volunteer here to read your post, otherwise he/she simply won't do it. Good luck. -
Need help with Inventory program part 6
if any one can help or give me a clue to how to do this Modify the Inventory Program to include an Add button, a Delete button, and a Modify button on the GUI. These buttons should allow the user to perform the corresponding actions on the item name, the number of units in stock, and the price of each unit. An item added to the inventory should have an item number one more than the previous last item.
? Add a Save button to the GUI that saves the inventory to a C:\data\inventory.dat file.
? Use exception handling to create the directory and file if necessary.
? Add a search button to the GUI that allows the user to search for an item in the inventory by the product name. If the product is not found, the GUI should display an appropriate message. If the product is found, the GUI should display that product?s information in the GUI.
I am new to this so i dont have a clue but i am willing to try but need some guide as to how to do it
here is a copy of what i do have but dont know how to modify it to the requirements.

Hello,
I am new to Java programming and I need some assistance in trying to complie my program correctly. I would greatly appreciate it.
I have started my program, but keep getting the same two compile errors.
C:\Program Files\Java\Product.java:91: illegal start of expression
public InventoryPart1(String name, double number, double units, double price)
^
C:\Program Files\Java\Product.java:113: class, interface, or enum expected
}//end class InventoryPart1
My assignment ask:
Choose a product that lends itself to an inventory (for example, products at your workplace, office supplies, music CDs, DVD movies, or software).
Create a product class that holds the item number, the name of the product, number of units in stock and the price of each unit.
Create a Java application that displays the product number, the name of the product, number of units in stock, the price of each unit, and the value of inventory (the number of units multiplied by price of each unit). Pay attention to the good programming practices in the text to ensure your source code is readable and well documented.
This is what I have so far.

Hello. I am somewhat new to Java and I was recently assigned to do a simple paint program. I have had no trouble up until my class started getting into the graphical functions of Java. I need help with my program. I am supposed to start off with a program that draws lines and changes a minimum of 5 colors. I have the line function done but my color change boxes do not work and I am able to draw inside the box that is supposed to be reserved for color buttons. Here is my code so far:

Hi there
I'm not sure how you wound up where you did. But you wound up in the Adobe Captivate forums. Please stand by as I move your thread to the Flash forums.

Modify the Inventory Program by adding a button to the GUI that allows the user to move to the first item, the previous item, the next item, and the last item in the inventory. If the first item is displayed and the user clicks on the Previous button, the last item should display. If the last item is displayed and the user clicks on the Next button, the first item
should display. the GUI using Java graphics classes.

I only see that you've added an actionlistener to the "first" button.
I recommend that you:
1) again, do this first in a nonGUI class, then use this nonGUI class in your GUI class.
2) Have a integer variable that holds the location of the current Product that your application is pointing to.
3) Have a method called getProduct(int index) that returns the product that is at the location specified by the index in your array / arraylist / or whatever collection that you are using.
4) Have your first button set index to 0 and then call getProduct(index).
5) Have your last button set your index to the last product in your collection (i.e.: index = productCollection.length - 1 if this is an array), and then call getProduct(index).
5) Have your next button increment your index up to the maximum allowed and then call getProduct(index). If it's an array it goes up to the array length - 1.
6) If you want the next button to cause the index to roll over to the first, when you are at the last then then increment the index and mod it ("%" operator) by the length of the array... -
Need help with inverter program
I am very new to labview and I need a lot of help fast. I have been given this vi program, which I have attached, that operates a bunch of inverters. The program is driving the inverter which in turn drives the agitator on a washing machine. The agitator goes in forward and reverse direction as a result of a relay within the inverter being supplied voltage to make it open and close. I need to supply voltage to the relay to make it go forward, reverse, and the pause before the next cycle begins. The current program has it doing a forward reverse and then immediately starts the next cycle. If any one can take a look at this program and let me know, first of all what the heck is going on, and second how to fix my problem, that would be incredibly helpful to me. If anyone has trouble opening the file let me know, I think attaching the vi should work but it may also look for a dll file or something when trying to open. Email me if you cannot open the file and I will send you the dll file as well. Your help is greatly appreciated. Thank you very much.

main2.vi 162 KBHello Tony,
you programmed it to run continously...
After the timed while loop runs through your array of ramp values you start again at index 0 (upper shift register). Instead of this end this while loop by combining the output from the comparison with your stop2 button (end loop when stop2 OR end of arrray). Now it will work.
Btw. why do you use "Insert to Array" when you want to concat 3 arrays (sequence frame 0)? Just use a "Build Array" and set "Concat Inputs" via mouse right-click.

Need help with basic program.....!
I've to write a program that generates a random number, which the user has to try and guess, after each guess they're told whether it's too high or too low etc., I've gotten this far, however, the user has only 10 guesses.... In my program I've used a while loop and the user gets an infinite number of guesses, I know I'm supposed to use a for loop, but can't seem to get it to work properly. Also, when the user guesses the number, the program then has to print out how many guesses it took, and I have no idea how to get it to do this AT ALL!!! I'd really appreciate some help with this, thanks v. much!!!!

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class app extends Applet implements ActionListener
JLabel lbl=new JLabel("Guess a number between 0 and 10:");
JTextField txtfield=new JTextField(20);
JButton button=new JButton("Guess...");
JLabel lbl2=new JLabel();
int randomnumber=Math.round((float)Math.random()*10);
public void init()
add(lbl);
add(txtfield);
add(button);
button.addActionListener(this);
public void actionPerformed (ActionEvent e)
String s=new String("");
s+=randomnumber;
if (e.getSource().equals(button) && txtfield.getText().equals(s))
setBackground(Color.white);
setForeground(Color.black);
lbl2.setText("Got it!");
add(lbl2);
validate();
else
setBackground(Color.white);
setForeground(Color.black);
if (Integer.parseInt(txtfield.getText())>randomnumber)
lbl2.setText("Too High!");
else
lbl2.setText("Too Low!");
add(lbl2);
validate();
Then create a HTML document in the classes folder:

It will do what you wish. If you want to have more then 10 numbers to guess, for example 100, do this:
int randomnumber=Math.round((float)Math.random()*100);
Does that answer your question? -
Help with Find / Replace button title tag contents (text)
Hi there,
I designed my site with Sitegrinder (Medialab) –
Currently all the title tags generated for buttons are the same as
the actual html page name.
The problem with this is that the tooltip which appears in
browsers when you hover over the button with the mouse gives you
the page name. Instead I want to use these tooltips to give the
user an indication of what the function of the button is.
An example: A zoom button above an image: Currenty the
tootlip says “zoom imagename pagename” – Instead
it should say “click here to zoom”.
I need help to get the Dreamweaver Find and Replace tool to
batch replace these tags for me for about a 100 pages.
Here is an example of the code:
<body>
<div id="id1zoomimpastooilweddingbutton"><a
href="zoomimpastooilwedding.html"
title="zoomimpastooilwedding"></a></div>
I only want to replace the text in the title tag - Since the
text “zoom” appears several times in the body, I
can’t get the Find tool to pick up and Replace the occurrence
of “zoom” in the title only…….
Options I’ve tried:
Search Current document: Search for: “specific
tag”: “title”, “containing”:
“text” = zoom (I’ve tried this with
“zoomimpastooilwedding” and zoom[^”]* with no
results
I’ve also tried: Search for: “specific
tag”: “body”, “containing”:
“specific tag” “title”
“containing”: “text” = zoom
etc……………..
I need help with what parameters to enter in order to find
and replace all the text within the title tag with my own text
Thanks very much!
AntonYou have ~ 100 pages, each of which has images with title
attributes (not
tags), all of which BEGIN with the letters "zoom"?
What do you want to replace that text with? Wouldn't it be
different for
each button? Or do you mean that you would do multiple
sitewide searches,
one for each button? This illustrates how wrong it is to not
use DW
Templates or server-side includes to simplify the management
of your
navigation elements....
Did you ask Medialabs if it would be possible to specify this
before
generating the HTML?
How did you like working with SiteGrinder? It looks like a
nice product to
me, although I'm not fond of the final results code-wise....

and for these programs, also i want help for:
They have errors and i cant fix'em
the commands that i've leaned:
If statements, for loops, while loops,do while, strings, math classes, swithc statement, else if,logical operators,methods, one and two dimensional arrays.

By the way im using Ready to program for the programming.You can't really believe that his brother did this
for him...I did miss that copyright line at the beginning when
I first looked it over, but you know, if it had been
his brother, I'd be kinda impressed. This wasn't a
25 line program. It actually would have required
SOME thought. I doubt my brother woulda done that
for me (notwithstanding the fact that I wouldn't need
help for that program, and my brother isn't a
programmer).I originally missed the comments at the top but when I saw the complexity of what was written then I knew that it was too advanced for a beginner and I relooked through the code and saw the comments. -

The problem I am having is getting the constructor to work with the rest of the program can someone please point out to me how to correct this. I have read my textbook as well as tutorials but I just don't seem to get it right. Please help.
P.S. I have never taken a programming class before so please be kind.Ok, I changed the name of the constructor:

Help With Scrolling Menu / Button Rollovers
First thank you to anyone who can answer and help with this
question.
http://paragon.sortismarketing.com
- at this link I have created a site with a simple scrolling menu.
Now what I want to happen is when you rollOver the buttons on the
scrolling menu they get larger and then smaller again after you
roll off them.
I know how to do this with tweening in a non moving
environment, by making them a movie clip instead of button. But for
some reason when I did this in this case it screwed the menu all up
and made it go crazy. Is there a way to do this with action script
that isn't going to screw up the underlying code for the
scrolling?You can use the below code also. As your mouse pointer goes
over the down, it will scroll down.
on(rollOver){
scrolltext.scroll -= 1; -
I seem to be having a little problem with my program. In my main program, depending on which method comes first, the other methods wont work for example the way my main program is not, with occurance method before removeLetter method, the occurance method works fine, but my removeLetter meth won't remove the letter. But if i switch the two and have removeLetter first then it will remove the letter, but my occurance method will come back say the letter is not in the word even when it is...can someone help me? Thanx in advance...
class CharacterRecurrance{
private int i=0;
private int occur=0;
void inString(String s, char n){
if(i<s.length()){
if(s.charAt(i)==n)
System.out.println("Yes, the letter" + " " + n + " " + "is present");
else{
i++;
inString(s,n);
else System.out.println("No, the letter" + " " + n + " " + "is not present");
void occurance(String s, char n){
if(i < s.length()){
if(s.charAt(i)==n){
occur++;
i++;
occurance(s,n);
else{
i++;
occurance(s,n);
else System.out.println("The letter" + " " + n + " " + "appears" + " " + occur + " " + "times");
void removeLetter(String s, char n){
if(i < s.length()){
if(s.charAt(i)==n){
s = s.replace(s.charAt(i),' ');
i++;
removeLetter(s,n);
else{
i++;
removeLetter(s,n);
else System.out.println(s);
class Program3_10{
public static void main(String[] a) {
CharacterRecurrance find = new CharacterRecurrance();
String word = "mississippi";
char letter = 's';
find.inString(word, letter);
System.out.println();
find.occurance(word, letter);
System.out.println();
find.removeLetter(word, letter);
}Or make it zero in the last step of each function. Like this-void occurance(String s, char n){
if(i < s.length()){
if(s.charAt(i)==n){
occur++;
i++;
occurance(s,n);
else{
i++;
occurance(s,n);
else{
System.out.println("The letter" + " " + n + " " + "appears" + " " + occur + " " + "times");
i=0; // reset to zero.

hi,
i study java at school and i need help with my project.
im doing a simple demonstration of a pathfinding program whose algoritm i read off Wikipedia (http://en.wikipedia.org/wiki/Pathfinding)where the co-ordinates of the start and end points
are entered and the route is calculated as a list of co-ordinates. Here is the section of code i am having trouble with-

int pass_pool[][]=new int[4][3];//stores the pool of squares which can be added to the list of direction
int path[][]= new int[10000][3];//stores actual path
int count=1;int note=10;int kk=0;
int curx,cury;
//the above arrays contain 3 columns - to store x and y co-ordinate and a counter variable(the purpose of which will become clear later)
grid_pool[0][0]=p;

ill be grateful if anyone can fix it. im done with the rest thoughdeath_star12 wrote:
hi,
i study java at school and i need help with my project.
im doing a simple demonstration of a pathfinding program whose algoritm i read off Wikipedia (http://en.wikipedia.org/wiki/Pathfinding)where the co-ordinates of the start and end points
are entered and the route is calculated as a list of co-ordinates. Here is the section of code i am having trouble with-
...The part "i am having trouble with" means absolutely nothing to the people who are answering questions here. It's like going to the doctor with a broken rib and just saying "doc, I don't feel so well". Get my point?
Also, please take the trouble to properly spell words and use a bit of capitalization. Your question is hard to read as it is, which will most probably cause (some) people not to help you. And lastly, please use code tags when posting code: it makes it so much easier to read (see: [Formatting Messages|http://mediacast.sun.com/users/humanlever/media/forums_text_editor.mp4]).
Thanks.
