I'm working on this very simple problem with a Java GUI:

Quote

Have the computer ask the name of the sales representative. After clicking the "Name Update" command button (that you will create), this name will then be included in all further questions. Ask the user for both the total sales for the person as well as the commission rate. The computer will then display the commission.

I have a few panels on the form to hold my containers, but what I don't understand is why is the second panel filling the form? Also how come my text boxes are so big? Does it have to do with the BoxLayout and BorderLayout?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

class form extends JFrame implements ActionListener {

	// these go in a panel together
	JPanel pnlName = new JPanel();
	JLabel lblName = new JLabel("Enter name: ");

Which IDE are you using?

//try to this code
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Test extends JFrame {
	JLabel northLabel;
	JLabel centerLabel;
	   
	JTextField northText;   
	JTextField centerText;
	JButton southButton;

	JPanel northPanel;
	JPanel centerPanel;
	JPanel southPanel; 
	

	public Test(){
	northLabel = new JLabel("label one");
	northText = new JTextField("text");
	northText.setPreferredSize(new Dimension(100, 20));//width and height
	northPanel = new JPanel();
	
	centerLabel = new JLabel("label two");
	centerText = new JTextField("text");
	centerText.setPreferredSize(new Dimension(100, 20));
	centerPanel = new JPanel();
	centerPanel.setVisible(false);

	southButton = new JButton("click");
	southButton.addActionListener(new ActionListener(){
		public void actionPerformed(ActionEvent e){
		centerPanel.setVisible(true);
		southButton.setVisible(false);
		}
	});	
	southPanel = new JPanel();
	southPanel.setLayout(new BorderLayout());
	
	northPanel.add(northLabel);

	add(southPanel, BorderLayout.SOUTH);
	
	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

	setVisible(true);
	}

	public static void main(String[] args){
