Write a circle class that has a field to represent the radius (as a double). The class should have a method to set the radius and get the radius. The class should have an empty constructor to initialize the radius to 1, and a non-empty constructor to initialize the radius to a given value. The class should be encapsulated.

Write a rectangle class that has fields to represent the width and height (as doubles). The class should have methods to: set the height, get the height, set the width, get the width, and a method to set both the width and height. The class should have a non-empty constructor to initialize the fields to given values. The class should be encapsulated.
