Overview

This assignment will produce a graphical game similar to the Whack-A-Mole arcade game, except it will be implemented using graphics and mouse clicks on an object that appears and disappears.

Program

Develop a class, WhackAMole, that implements the interfaces Runnable and MouseListener and has the following attributes (instance variables):

a static JFrame object

a static Graphics object

a static Container object

a static int for the x-coordinate of a mouse click

a static int for the y-coordinate of a mouse click

a static int for the number of points accumulated so far

a static int for the x-coordinate of a ball

a static int for the y-coordinate of a ball

Also, give it the following methods:
