Write an application that allows the user to play a game, the goal of which is to prevent a bouncing ball from falling off the bottom of the application. When the user presses the S key, the game starts and a blue ball will bounce off the top, left and right sides (the “walls”) of the application. There should be a horizontal bar on the bot- tom of the application, which serves as a paddle, to prevent the ball from hitting the bottom of the application (the ball can bounce off the paddle, but not off the bottom of the applica- tion.) The user can move the paddle using the left and right arrow keys. If the ball hits the paddle, the ball should bounce up, and the game should continue. If the ball hits the bottom of the application, the game should end. Most of the geometr
a) Copying the template to your working directory. Copy the C:Examples Tutorial22ExercisesBouncingBall directory to your C:SimplyJava directory.
b) Opening the template file. Open the BouncingBall.java file in your text editor.
c) Writing code to start the game. In line 131 (in the bouncingBallKeyPressed method), begin an if statement to determine if the S key has been pressed. You will need to use the KeyEvent constant VK_S. Inside the if statement, start ballTimer by calling the start method of ballTimer, which is a Timer declared as an instance variable in the template.
d) Inserting code to move the paddle left. Following the if statement you added in Step c, add an else if statement that tests if the user pressed the left arrow key and if the paddle’s horizontal position, stored in rectX, is greater than ten. You will need to use KeyEvent constant VK_LEFT. If the paddle’s horizontal position equals ten, the left edge of the paddle is touching the left wall and the pad
