Hi

1. How to disable the tab key in a JtextArea.

2. I have multiple JTextField say tx1,tx2,tx3,tx4.
Once I have enter the tx1 filed, or once my cursor goes to tx2 box, I wud like to auto complete the rest of tx2,tx3,tx4.

Assume that I already have an array of strings[][] to fill up the rest.

hi,  try this , you have to set FocusTraversalKeys for JTextArea

import javax.swing.*;
import java.awt.*;
import java.util.*;
public class test extends JFrame
{
      public test()
      {
            JPanel jp1=new JPanel();
            this.setSize(new Dimension(400,400));
            JTextArea jta=new JTextArea("adfs adf adsf afd");
            
            jta.setPreferredSize(new Dimension(200,200));
            
            Set set = new HashSet(jta.getFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS));
            set.clear();   // Call clear() if you want to eliminate the current key set
            set.add(KeyStroke.getKeyStroke("TAB"));
            jta.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set);
            jp1.add(jta);
            
            JTextArea jta2=new JTextArea("adfs adf adsf afd");
            jta2.setPreferredSize(new Dimension(200,200));
            
            Set set1 = new HashSet(jta2.getFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS));
            set1.clear();   // Call clear() if you want to eliminate the current key set
            set1.add(KeyStroke.getKeyStroke("TAB"));
            jta2.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set1);
            
            jp1.add(jta2);
            
            this.getContentPane().add(jp1);
            
            this.setVisible(true);
      }
      public static void main(String args[])
