Java Exercise #65: Simple Event Demo

This exercise is to demonstrate simple Event handling in Java GUI. Buttons are source of ActionEvent. Clicking a button invokes the actionPerformed method on the registered listeners. In this implementation, it will invoke getActionCommand() which by default returns the label of the button. The program also uses the event.getWhen() to return the time in long when the event was generated

This implementation also uses an inner class to create listener instance.

Exercise: Write a program that creates two buttons and print event information when clicked!
