How to = TextArea - so the text disappears?

Question

What are the bits I need, so that when a user fills in a form eg;
TextArea TA1 = new TextArea("Enter your name here");
1. So the text is hilighted in dark blue.
2. So when the user clicks within the TextArea, the whole text vanishes.
3. How to reconstruct the same if the form is reset (may not require additional).
Sample code warmly welcomed

Answer 1

Here is how you would do it using a JTextField. I would assume it would also work for a TextArea.
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
import javax.swing.plaf.basic.*;
import javax.swing.plaf.*;
public class TextFieldTest extends JFrame
    public TextFieldTest()
          FocusAdapter focusAdapter = new FocusAdapter()
               public void focusGained(FocusEvent e)
                    JTextComponent component = (JTextComponent)e.getSource();
                    component.selectAll();
          JTextField textField1 = new JTextField( "one two three four five" );
          textField1.addFocusListener( focusAdapter );
          getContentPane().add( textField1, BorderLayout.NORTH );
          JTextField textField2 = new JTextField( "abcdefg" );
          textField2.setMargin( new Insets( 5, 5, 5, 5 ) );
          textField2.addFocusListener( focusAdapter );
          getContentPane().add( textField2, BorderLayout.SOUTH );
    public static void main(String[] args)
     TextFieldTest frame = new TextFieldTest();
        frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
        frame.pack();
        frame.setVisible(true);
}Note: I would use a TextField to enter a users Name. A TextField is typically used to enter a single line of text. A TextArea is used when you need to enter multiple lines of text.
