Using ActionListener for AWT TextField

The following illustrates use of ActionListener for AWT TextField.

import java.awt.*;
import java.awt.event.*;
class TextFieldAction extends Frame
TextField t;
    public TextFieldAction()
    private void createAndShowGUI()
        setTitle("TextField with ActionListener demo");
        setLayout(new FlowLayout());
        // Create simple TextField that shows 20 chars
        t=new TextField(20);
        // Add ActionListener
        t.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent ae)
                // Change frame title
        // Add the textfield
    public static void main(String args[])
        new TextFieldAction();
TextFieldAction(): Code illustrating ActionListener on AWT TextField is written here.
new TextFieldAction(): Code that initializes the GUI is written here.

Just type the text and hit enter to change the title because ActionEvent is generated.
