Chapter 8, Problem 5E
Create a class Square derived from DrawableShape, as described in the previous exercise. A Square object should know the length of its sides The class should have an accessor method and a mutator method for this length. It should also have methods for computing the area and perimeter of the square. Although characters are taller than they are wide—so the number of characters in the vertical sides will differ from the number in the horizontal sides—you need not worry about this detail when drawing the square.

For this assignment, you are asked to create a ColorfulBouncingCircle class.
ColorfulBouncingCircle should extend ColorfulCircle. Unlike the other Circle classes, it will include a velocity for the x and y axes. The constructor for ColorfulBouncingCircle includes these parameters:public ColorfulBouncingCircle(double radius, double centerX, double centerY, Color color, double xVelocity, double yVelocity)
Note that we are treating x as increasing to the right and y as increasing down, as with Java’s graphics coordinates system. This was also seen with Circle’s draw method.
ColorfulBouncingCircles will bounce around in a playing field which the tester will provide. The ColorfulBouncingCircle class should have a public static method to set the playing field width and height:
public static void setPlayingFieldSize(double newWidth, double newHeight)
ColorfulBouncingCircle will also include a method which should alter its centerX and centerY with each time tick (similar to a metronome’s…

Text Class
The Text class inherits from Drawable and it will be used to display the player’s score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface.
This is the Drawable Class
PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS.
Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.
