  • Need help for writing extract program

    hi
    i need help for writing extract program to retriew data from legacy system.
    i already developed bdc programs for me31k and me21.
    my requirement is to write extract program s for those t.codes.
    to retriew data from legacy system and stored in flat file.

    i need help with a java program. it is a program that allows the user to enter a student's GPA, number of extracurricular activities, and number of service activities. The user can not enter a gpa above 4.0 or below 0. The user can not enter a negative number for the number of both activities. If the student meets the following criteria: 1) GPA of 3.8 or above and at least one extracurricular activity and one service activity, 2) GPA below 3.8 but at least 3.4 and a total of at least three extracurricular and service activities, 3) GPA below 3.4 but at least 3.0 and at least two extracurricular activities and three service activities, the message "Scholarship candidate" should display. If the student does not meet the criteria above, then the message"not a candidate" should display. Can you help me, please?
    You haven't posted ANY 'java program' for us to help with.
    The forum is NOT a coding service. It is to help you with YOUR code.
    Post the code you have written and SHOW us (don't just tell us) how you compile it and execute it and the results you get. Then we can help you with any problems you are are having.
    If you need help understanding just what the program should be doing you need to ask your instructor to clarify the assignment.

              catch(IOException a)
                         System.out.println(a.getMessage());
    }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..

    Like 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

    I need help!!!
    look at how i programmed it ....
    But i got one thing on my mind that is confusing me, its this problem (im trying to let the com display the grades being inputed in the statement.. )

  • Need Help with simple array program!

    Hi, I have just recently started how to use arrays[] in Java and I'm a bit confused and need help designing a program.
    What this program does, it reads in a range of letters specified by the user. The user then enters the letters (a, b or c) and stores these characters into an array, which the array's length is equal to the input range the user would enter at the start of the program. The program is then meant to find how many times (a,b and c) appears in the array and the Index it first appears at, then prints these results.
    Here is my Code for the program, hopefully this would make sense of what my program is suppose to do.
    import B102.*;
    class Letters
         static int GetSize()
              int size = 0;
              boolean err = true;
              while(err == true)

                   size = Keybd.in.readInt();
                   err = Keybd.in.fail();
                   Keybd.in.clearError();

    }     Some errors i get with my program are:
    When reading in the letters to store into the array, I get the last letter I entered placed into the entire array. Also I believe my code to find the Index is incorrect.
    Example Testing: How many letters would you like to read? 3
    Enter letter (a, b or c) (# to quit): a
    Enter letter (a, b or c) (# to quit): b
    Enter letter (a, b or c) (# to quit): c
    It prints "There are no a's'" (there should be 1 a at index 0)
    "There are no b's" (there should be 1 b at index 1)
    and "There are 3 c's, first appearing at index 0" ( there should be 1 c at index 2)
    The last thing is that my code for when the user enters "#" that the input of letters would stop and the program would then continue over to the counting and searching part for the letters, my I believe is correct but I get the same problem as stated above where the program takes the character "#" and stores it into the entire array.
    Example Testing:How many letters would you like to read? 3
    Enter letter (a, b or c) (# to quit): a
    Enter letter (a, b or c) (# to quit): #
    It prints "There are no a's'" (should have been 1 a at index 0)
    "There are no b's"
    and "There are no c's"
    Can someone please help me??? or does anyone have a program simular to this they have done and would'nt mind showing me how it works?
    Thanks
    lou87.

    Without thinking too much...something like this
    for(int start = 0; start < size; start++) {
                System.out.println("Please enter a letter (a, b or c) ("+size+" max), enter # to stop:");
                input = Keybd.in.readChar();
                while((input != 'a') && (input != 'b') && (input != 'c') && (input != '#')) {
                    Screen.out.println("Invalid Input");
                    System.out.println("Please enter a letter (a, b or c) ("+size+" max, enter # to stop:");
                    input = Keybd.in.readChar();
                if(input == '#') {
                        break;
                letter[start] = input;
            }you dont even need to do start = size; coz with the break you go out of the for loop.

  • Need Help With D&D Program

    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) {
                   Debug.trace(e.toString());

  • Need Help With Simple ABAP Code

    Hello,
    I'm loading data from a DSO (ZDTBMAJ) to an Infocube (ZCBRAD06). I need help with ABAP code to some of the logic in Start Routine. DSO has 2 fields: ZOCTDLINX & ZOCBRDMAJ.
    1. Need to populate ZOCPRODCD & ZOCREFNUM fields in Infocube:
        Logic:-
        Lookup /BI0/PMATERIAL, if /BIC/ZOCBRDMAJ = /BIC/OIZOCBRDMAJ
        then /BIC/ZOCPRODCD = ZOCPRODCD in Infocube
               /BIC/ZOCREFNUM = ZOCREFNUM in Infocube         
    2. Need to populate 0G_CWWTER field in Infocube:
        Logic:
        Lookup /BIC/PZOCTDLINX, if /BIC/ZOCTDLINX = BIC/OIZOCTDLINX
        then G_CWWTER = 0G_CWWTER in Infocube.
    I would need to read single row at a time.
    Thanks!

    I resolved it.

  • I need help removing a malicious program form my mac!

    Hello, I am 99% sure I accidentally acquired/downloaded a malicious program on my mac and I am new to macs and need help removing it!
    I have growl and the other day it notified me that screen sharing, file sharing and web sharing were all turned on at once. As soon as I saw this I quickly got off of the internet and found out how to disable them.
    Also, three programs kept requesting to access the internet and I denied them of course. Their names were: nmbd, netsessionmac1225fd0, and krb5kdc.
    Like I said I am new to macs and need some help fixing this problem. So, if anyone has any ideas that would help a lot.
    I already have screen sharing, file sharing, and web sharing turned off and now it requires a password to access (which i changed after i disabled them) but I want to ask some mac people if I need to do anything else, thanks!

    By the way, a big thank you to everyone who has helped so far..
    Here is the list of my running programs and keep in mind that I do have my firewall turned on as well as file sharing, screen sharing, and web sharing turned off so the suspect program may not be running?

    Hey people I need bit of help writting a very basic program for a project due on wednesday of this week. I am new at this I wanted to see if I could get some help from you.
    I need basically to write a program that when you insert the year of birth it displays the chinease symbol or charater corresponding to the chinease horoscope, for example if I was born in 1982, my ymbol will be the dog... each animal repeats each 12 years, and there are 12 animals,,, some friends told me to do it with a do while, but as I am trying, it does not work that well or I don't do it well, ejejeje
    Please help me
    Juan Antonio

    If you show us what you've done you are more likely to get help.
    I don't think you need loops, have you been taught about the modulus operator "%" ?
