Help with displaying JLabels in new window?

[John Corkrend]

So here is my code in a summary, a button click from another class sends it here where it launches the new window.

How do I get the contents of stringFirst to display on the new window? Note: Any classes/textfields/buttons used in this code are in a seperate class that I don't is necessary to solve this issue.

package data;

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


public class DataEventListener extends JFrame implements ActionListener
	{  


	class newWindow extends DataApplication {
		String stringFirst = firstName.getText();
		String stringLast = lastName.getText();
		String stringEmail = emailEntry.getText();
		String stringName = nameEntry.getText();
		
	}
	
	public DataEventListener() {
		super ("Test");
		setSize (300,220);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
	}

	

public void actionPerformed(ActionEvent event)   
   {   
      JButton doneButton = (JButton)event.getSource();
      setVisible(true);
      doneButton.setEnabled(false);
   }   
}

if the original window (JFrame ) is DataApplication, it won't work the way you're trying it.

1) the new window should be a JDialog - very rare to have 2 JFrames running around.
2) in the constructor of the dialog, pass a reference of the DataApplication instance to the dialog
3) set the various label texts to those from the instance passed
