Hello...

Like the title already says, i have a Panel with a TextField and when a text is entered, i want it to appear on a JLabel that is located on another Panel. Can someone give me the Syntax? Or is it more complicated to do?
I do not use a Database since i dont know yet how to imply it in Java.
Thank you for your help!!!

To give you my code for my first Panel that contains the TextField(txtName)

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

import java.awt.event.*;


public class NameScreen extends JDialog {
	
	JPanel frmName = new JPanel();
	JLabel lblJtitle = new JLabel("Java Questions");
	JLabel lblName = new JLabel("Please Enter Your Name:");
	JLabel lblImage7 = new JLabel(new ImageIcon("D:\\Schule\\Java Projects\\Final Java2\\geld_0010.gif"));
	JTextField txtName = new JTextField("");
	JButton cmdOk = new JButton("OK");
	JButton cmdCancel = new JButton("Cancel");
	
	
	
	public NameScreen() {
		
		setSize(450,300);
		setLocation(600,300);
		setTitle("Do you know...?");
		setVisible(true);
		setResizable(false);
		frmName.setLayout(null);
		
		
		frmName.setBackground(Color.BLACK);
		
		lblJtitle.setBounds(163,100,170,30);
		lblJtitle.setFont(new Font("Arial", Font.BOLD, 16));
		lblJtitle.setForeground(Color.WHITE);
		
		lblName.setBounds(50,140,180,40);
		lblName.setForeground(Color.YELLOW);
		lblName.setFont(new Font("Arial", Font.BOLD, 14));
		
		cmdOk.setBounds(120,200,80,30);
		cmdCancel.setBounds(250,200,80,30);
		
		txtName.setBounds(240,140,150,30);               //TextField is here
		txtName.setFont(new Font("Arial", Font.BOLD, 20));
		
		lblImage7.setBounds(180,20,100,80);
		
		frmName.add(lblName);
		frmName.add(txtName);
		frmName.add(lblImage7);
		frmName.add(cmdOk);
		frmName.add(cmdCancel);
		frmName.add(lblJtitle);
		
		
		getContentPane().add(frmName);
		
		
		
		cmdOk.addActionListener(new ActionListener() 
		{
	       
	    		public void actionPerformed(ActionEvent e)
	    		{
	    			dispose();
	    			new GameScreen().show();
	    				
	    		}	
	    		
	    });
		
		
		cmdCancel.addActionListener(new ActionListener() 
		{
	       
	    		public void actionPerformed(ActionEvent e)
	    		{
	    			dispose();
	    			new ChoosingScreen().show();
	    				
	    		}	
	    		
	    });
		
				
	}	

}

What about passing the variable as a parameter for the other panels constructor?

You can pass it through the constructor of the second panel's class constructor, like this:

public GameScreen(String name)
{
...
}

So when you call it from the first panel, you call it this way:

new GameScreen(txtName.Text).show();

Thank you i will try it... But this is true to pass it from 1 Panel to another one?
I dont need to indicate the class where the textField is located?
