Trouble with Swing / Jframes

[tknopriest]

OK... so I am pretty new to Java and need some help.

I'll try to explain as best I can... I am trying to create a frame that will be a "menu frame" and then based on which option the user picks (JButton) it will then run the version of the program they have picked.

So first window is just a menu with 3 buttons: Version 1, Version 2, and EXIT.

What is the best way to implement this?
I know I don't know much... but how do I get the other 2 programs I have already written in here and linked to the buttons I created?
(the other 2 programs fill the same size frame) Right now the buttons just exit out of the program as a placeholder.

Any help would be appreciated.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.JButton;
import javax.swing.JTextField;
import java.text.DecimalFormat;

public class choiceMenu extends JPanel{

	//Variables
	private JLabel choiceLabel;
	private JButton exitButton, v1Button, v2Button;

public choiceMenu()
	{
	//Header Label
	choiceLabel = new JLabel ("                    *Please Choose A Method*                         ");

	//create the reset button
	v1Button = new JButton("Version 1: User Defined Terms & Rates");
	v1Button.addActionListener(new ActionListener()
		{
		public void actionPerformed(ActionEvent ae)
			{
			System.exit(0);
			}
		});

	//create the exit button
	v2Button = new JButton         ("     Version 2:  Preset Terms & Rates      ");
	v2Button.addActionListener(new ActionListener()
		{
		public void actionPerformed(ActionEvent ae)
			{
			System.exit(0);
			}
        });

    //create the exit button
	exitButton = new JButton         ("                       EXIT PROGRAM                       ");
	exitButton.addActionListener(new ActionListener()
		{
		public void actionPerformed(ActionEvent ae)
			{
			System.exit(0);
			}
        });

		//labels & fields
	add(choiceLabel);
	add(v1Button);
	add(v2Button);
	add(exitButton);
	}

	private static void createAndShowGui()
	{
		JFrame frame = new JFrame("Mortgage Calculator");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		choiceMenu calculator = new choiceMenu();
		frame.setContentPane(calculator);

		frame.setSize(425,550);
		frame.setVisible(true);
	}

	public static void main(String[] args)
	{
		javax.swing.SwingUtilities.invokeLater(
		new Runnable()
		{
			public void run()
			{
				createAndShowGui();
			}
		}

		);
	}

}

You don't run the programs, you call the methods. If the other programs are inside a main, then take that code and declare it as a method and call the method. For arguments, You might want to add some JTextFields. Check the API for JTextFields.

An example on how to do that thing with the main:

public static void main(String [] args) {
     [B]int a = 5;
     int b = 4;[/B]
     [B]int sum = a + b;[/B]
     System.out.println("Sum = "+sum);
}

Should be:

public class SomeUtilities {
    public static int getSum([B]int a, int b[/B]) {
        [B]int sum = a + b;[/B]
        return [B]sum[/B];
   }
}

At your "swing" code, you call the methods from the other classes. If you don't know how to do that I suggest you study some more on how to call and declare methods.

I know how to run, and maybe that is a bad way to word it, other methods... my "calculate" button calls on the "calculator" method to do the match and come back with the numbers...

but my big problem I guess is making so that if I click one of those buttons on that first piece of code that I put up, that it then hides/closes/whatever the menu window(frame) and opens up a new frame/window with all of the proper GUI and calculations.

Alternatively "clearing" the current frame and replacing that GUI with the GUI I used in the other programs would work as well.
