A class called MyCircle, which models a circle with a center (x,y) and a radius, is designed as shown in the class diagram. The MyCircle class uses an instance of MyPoint class (created in the previous exercise) as its center. The class contains: Two private instance variables: center (an instance of MyPoint) and radius (int). A constructor that constructs a circle with the given center's (x, y) and radius. An overloaded constructor that constructs a MyCircle given a MyPoint instance as center, and radius. A default constructor that construct a circle with center at (0,0) and radius of 1. Various getters and setters. A toString() method that returns a string description of this instance in the format "MyCircle[radius=r,center=(x,y)]". You shall reuse the toString() of MyPoint. getArea() and getCircumference() methods that return the area and circumference of this circle in double. A distance(MyCircle another) method that returns the distance of the centers from this instance and the given MyCircle instance. You should use MyPoint’s distance() method to compute this distance. Write the MyCircle class. Also write a test driver (called TestMyCircle) to test all the public methods defined in the class
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
A class called MyCircle, which models a circle with a center (x,y) and a radius, is designed as shown in the class diagram. The MyCircle class uses an instance of MyPoint class (created in the previous exercise) as its center.
The class contains:
Two private instance variables: center (an instance of MyPoint) and radius (int).
A constructor that constructs a circle with the given center's (x, y) and radius.
An overloaded constructor that constructs a MyCircle given a MyPoint instance as center, and radius.
A default constructor that construct a circle with center at (0,0) and radius of 1.
Various getters and setters.
A toString() method that returns a string description of this instance in the format "MyCircle[radius=r,center=(x,y)]". You shall reuse the toString() of MyPoint.
getArea() and getCircumference() methods that return the area and circumference of this circle in double.
A distance(MyCircle another) method that returns the distance of the centers from this instance and the given MyCircle instance. You should use MyPoint’s distance() method to compute this distance.
Write the MyCircle class. Also write a test driver (called TestMyCircle) to test all the public methods defined in the class
