Enhance the ButtonViewer program so that it prints the time at which the button was clicked.
This is the ButtonViewer I have:
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
/**
This program demonstrates how to install an action listener.
*/
public class ButtonViewer
{
private static final int FRAME_WIDTH = 100;
private static final int FRAME_HEIGHT = 60;
public static void main(String[] args)
{
JFrame frame = new JFrame();
JButton button = new JButton(\"Click me!\");
frame.add(button);
ActionListener listener = new ClickListener();
button.addActionListener(listener);
frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
Click Listener:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
/**
An action listener that prints a message.
*/
public class ClickListener implements ActionListener
{
public void actionPerformed(ActionEvent event)
{
System.out.println(\"I was clicked.\");
}
}
