—  Draw an object that moves horizontally and vertically.

§  The object should have a width 1/10 of the size of the window and the height should be 1/10 of the size of the window.

§  The initial position of the object should be x=50, and y=50

§  The initial shape of the object is a ball.

 

—  Draw a different object depending upon a mouse press:

§  The first time the mouse button is pressed the object to be drawn is a box.

§  The next time the mouse button is pressed the object to be drawn is a ball.

—  Set different colors for the ball or box as follows:

§  If the object is in the upper-left quadrant of the output window, the color is red.

§  If the object is in the upper-right quadrant of the output window, the color is green.

§  If the object is in the lower-left quadrant of the output window, the color is blue.

§  If the object is in the lower-right quadrant of the output window, the color is black.

 

—  Direction of object:

§  When the edge of the object hits any side of the screen, the object should reverse direction.

 

—  Use a variable of type boolean in the code that controls the shape of the object; the first time the mouse button is clicked, the object changes to a box.  The next time the mouse button is clicked, the object returns to a ball; this functionality continues to reverse each time the mouse button is clicked; update the value of the boolean variable in the mousePressed() method.
