Question Two $(15$ marks$)$

Design a Java class named Circle that contains:

Data field:

private double radius

Methods

A constructor that creates circle with the specified radius

Methods to set and get radius

A method named calculatePerimeter that calculates the perimeter of the circle.

A method

named calculateArea that calculates the area of the circle.

Create a subclass "Cylinder" of "Circle" as follows:

Cylinder has a private double height data field. A constructor that creates cylinder with the specified height. A method named calculateVolume that calculate the volume of the cylinder.

Override the calculateArea method in the circle class to calculate the surface area of the cylinder.

Write a test program that creates a Circle and Cylinder and invoke their methods.

Formula: Perimeter $of$ circle $=2r$

Volume $of$ cylinder $=r^{2}h$
