Thread: Java Learning Help: JOptionPane / Listener

Hey,

I'm trying to learn Java (The GUI part right now), but my code won't do as intetden.
What it should do:
When I press enter in a field, then show the dialog (See fat text in code (Can't use FAT in code, so look at the [/B])

My Problem
It will only show the message in the password-part (Which I think is stupid)


Code:

public class EHTwo extends JFrame{
 
	private JTextField itemOne;
	private JTextField itemTwo;
	private JTextField itemThree;
	private JPasswordField passwordField;
 
	public EHTwo(){
 
		super("The Title");
		setLayout(new FlowLayout());
 
		//10 is the max length.
		itemOne = new JTextField(10);
 
		//This is like a PROMT
		itemTwo = new JTextField("TRY ENTER!");
 
		itemThree = new JTextField("Uneditebale", 20);
		//This makes sure that the user can't edit it.
		itemThree.setEditable(false);
 
		//mypass is the default password
		passwordField = new JPasswordField("mypass");
 
		add(itemOne);
		add(itemTwo);
		add(itemThree);
		add(passwordField);
 
 
		TheHandler handler = new TheHandler();
 
 
		itemOne.addActionListener(handler);
		itemTwo.addActionListener(handler);
		itemThree.addActionListener(handler);
		passwordField.addActionListener(handler);
 
	}
 
 
 
	//When a class is inside another class, then it will INHERITANCE all the stuff form the first.
	private class TheHandler implements ActionListener{
 
 
		//This has to be name actionPerformed. (ActionEvent) is the type. event is the name.
		public void actionPerformed(ActionEvent event){
 
			//This is the final string we output.
			String string = "";
 
 
 
			[B]//This is to check which box is clicked.[/B]
			if(event.getSource()==itemOne){
				//This is going to set the string.
				string=String.format("Field One %s", event.getActionCommand());		//event.getActionCommand() means that it is gonna get the information form the "box" /point /object it's at.
			}
			else if(event.getSource()==itemTwo){
				string=String.format("Field Two %s", event.getActionCommand());
			}
			else if(event.getSource()==itemThree){
				string=String.format("Field Three %s", event.getActionCommand());
			}
			else if(event.getSource()==passwordField){
				string=String.format("Password Field is: %s", event.getActionCommand());
 
			JOptionPane.showMessageDialog(null, string);
 
			}
 
		}
 
	}

Thanks, I hope that you can read the code, if not then message me

I recommend that you have a much better understanding of the basics before beginning your GUI study.
