While using the MyPoint and Circle classes that were created, now create a class that represents a cylinder and a class to represent a rectangle. First step is to create a UML diagram that would include MyPoint, circle, cylinder, and rectangle. After this write cylinder.java and rectangle.java. Cylinders are circles with a height, so include 2 private data members. ( Circle base and integer height). Cylinders should include the standard accessor/mutator methods, object methods, (toString, equlas, clone) as well so that it calculates its volume. Rectangles are a shape with an intger width and height with an anchor MyPoint to determine the position. Rectangles should include the standard accessor/mutator methods, object methods (toString, equlas, clone) and operations to calculate its area and perimeter.

Please attact a PNG of your UML diagram and the cylinder.java and rectangle.java files.
