Hi!

public class RLTextField {
        public static String s = new String();

        public static void main(String[] args) {
            JFrame frame = new JFrame("RigthToLeftTextField");
           final JTextField textField = new JTextField(30);
           textField.setHorizontalAlignment(SwingConstants.RIGHT);
           frame.getContentPane().add(textField);
     
       class MyDocListener implements DocumentListener {
           public void insertUpdate(DocumentEvent evt) {
             Keymap km = textField.getKeymap();
             KeyStroke ks_home = KeyStroke.getKeyStroke(KeyEvent.VK_HOME, 0);
             KeyStroke ks_end = KeyStroke.getKeyStroke(KeyEvent.VK_END, 0);

             Action act_home = km.getAction(KeyStroke.getKeyStroke
(KeyEvent.VK_HOME, 0));
             Action act_end =
km.getAction(KeyStroke.getKeyStroke(KeyEvent.VK_END, 0));
        
             km.removeKeyStrokeBinding(ks_home);
             km.removeKeyStrokeBinding(ks_end);
                
             km.addActionForKeyStroke(ks_home, act_end);
             km.addActionForKeyStroke(ks_end, act_home);
}
}
textField.getDocument().addDocumentListener(new MyDocListener());
