Enhance the ButtonViewer program so that it prints the time at which the button was clicked.

Use the following class as your main class:
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);
}
}

You need to supply the following class in your solution:
ClickListener

Do not modify the following:

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);
}
}
