Writing a Java GUI displaying time when button clicked
Not what you're looking for?
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);
}
}.
