Java Applet

Modify the Breakout game (shown below with codes) to create the ice breakout game. You may want to check the game online (http://www.miniclip.com/games/ice-breakout/en/). Your game applet shall be similar to on-line game. However, no need for ? Background image or image effect. A basic color is just fine. ? No need for level. Only score to be displayed. ? No shadow to be drawn. The swing is basically a circle + a line. ? Bricks are rectangular objects as we did in lab. ? You may state any other assumptions. Screen shots are shown below. However, you must play the game to understand the requirements.
