    Default How do you add GUI to this java program?

    Ok, I wasn't sure where to post this problem since I don't know if this is classified under the new to java or advanced.

    I know only basic stuff in java. And I need to create a GUI for this type of program. It shows your credit card info. It has some other classes and makes use of the rmiregistry. This works fine in console but I need to show it in a GUI. The first thing that promps here is to enter your name (java Shopper localhost *my name*). Then it shows you your credit card info. Can anyone help me? Please and thank you

    import java.rmi.*;
    import javax.swing.*;
     
    public class Shopper {
        public static void main(String args[])
        {
            CreditManager cm = null;
            CreditCard account = null;
     
            if(args.length<2)
            {
                System.err.println("Usage:");
                System.err.println("java Shopper <server> <accountname>");
                System.exit(1);
            }
            try
            {
                String url = new String("//"+args[0]+"/cardManager");
                System.out.println("Shopper: lookup cardManager, url="+url);
                cm = (CreditManager) Naming.lookup(url);
            }catch(Exception e)
            {
                System.out.println("Error in getting Card Manager "+e);
                System.exit(1);
            }
     
            try
            {
                account = cm.findCreditAccount(args[1]);
                System.out.println("Found account for "+args[1]);
            }catch(Exception e)
            {
                System.out.println("Error in getting acocunt for "+args[1]);
                System.exit(1);
            }
     
            try
            {
     
                	 System.out.println("Available credit is "+account.getCreditLine());
                System.out.println("Changing pin number for account");
                account.setSignature(1234);
                System.out.println("Buying a new watch for $100");
                account.makePurchase(100.0f, 1234);
                System.out.println("Available credit is now "+account.getCreditLine());
                System.out.println("Buying a new pair of shoes for $160");
                account.makePurchase(160.0f, 1234);
                System.out.println("Cardholder: Paying off $136 of balance");
                account.payTowardsBalance(136.0f);
                System.out.println("Available credit is now "+account.getCreditLine());
     
            }catch(Exception e)
            {
                System.out.println("Transaction error for "+args[1]);
            }
     
            System.exit(0);
        }
     
    }

    Hey leyla

    Check out the Sun Swing tutorials and create a basic GUI...

    Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

    Once you understand the basics you can easily make the GUI for your program.
