Java 2. Every circle has a center and a radius.- Given the radius, we can determine the circle's area and circumference.- Given the center, we can determine its position ini the x-y plane. Thecenter of a circle is a póint in the x-y plane.- Design the class Circle that can store the radius and center of thecircle. Since the center is a point in the x-y plane , we can use the Pointclass that we already designed in #1, we must derive the class Circle fromthe class Point. We should be able to perform the usual operations on acircle, such as setting the radius, printing the radius, calculating and printingthe area and circumference, and carrying out the usual operations on thecenter.The class Circle should contain the folowing methods and data member:12. protected member radius13. default constructor14. constructor with parameters15. setCircle(x)16. getRadius(')17. setRadius(x )18. toString( )19. equals(x)20. makeCopy(x)21. getCopy(')22. printCircle( )23. area( ) -x • r224. circumference( ) - 2 • z • radius The output should show the following:Initialize myCircle to (5.00, 4.00, 7.23)Initialize yourCircle to (Õ.00, 0.00,0.00)Set yourCircle to (5.00, 45.00, 82.20)Determine the area of yourCircle: ???Determine the circumference of yourCircle: ???- Determine if the 2 circles are equal or not- Enter the center as (6.50, 8.75)Enter the radius as 13.0Set myCircle with (6.50, 8.75, 13.00)Copy myCircle into yourCircle and then print yourCircle.

Actually, Java is a general-purpose also class-based, object-oriented programming language designed for having lesser implementation dependencies. It is a kind of computing platform for application development. It is fast, secure, and reliable, therefore. a. Features of Java Programming Language are: b. Java is Simple. c. Java is an Object-Oriented programming language. d. Java is Familiar. e. Java supports Functional programming. f. Java is Secure. g. Java is Platform Independence h. Java is Multithreaded. i. Java is High Performance.ANSWER:- /*Java program that test the methods of Circle class. in main method * */ //TestCircle.java public class TestCircle { public static void main(String[] args) { Circle myCircle=new Circle(5.00, 4.00, 7.23); Circle yourCircle=new Circle(); yourCircle.setCircle(5.00, 45.00); yourCircle.setRadius(82.20); System.out.println("myCircle"); System.out.println(myCircle); System.out.println("yourCircle"); System.out.println(yourCircle); System.out.printf("area of your circle: %.2f\n",yourCircle.area()); System.out.printf("circumference of your circle: %.2f\n",yourCircle.circumference()); if(myCircle.equals(yourCircle)) System.out.println("myCircle and yourCircle are equal"); else System.out.println("myCircle and yourCircle are not equal"); yourCircle.setCircle(6.50, 8.75); yourCircle.setRadius(13); System.out.println(yourCircle); myCircle.setCircle(6.50, 8.75); myCircle.setRadius(13); yourCircle=myCircle.getCopy(); System.out.println("myCircle"); System.out.println(myCircle); System.out.println("yourCircle"); System.out.println(yourCircle); } } ------------------------------------------------------------------------------------------------------------ //Circle.java public class Circle { //private data members private double xValue; private double yValue; private double radius; //default constructor public Circle() { xValue=0; yValue=0; radius=0; } //parameter constructor public Circle(double x, double y, double r) { xValue=x; yValue=y; radius=r; } //Return radius public double getRadius() { return radius; } //set radius public void setRadius(double radius) { this.radius = radius; } //Set circle with x and y values public void setCircle(double x,double y) { xValue=x; yValue=y; } //Override the toStirng method public String toString() { return String.format("(%.2f, %.2f) ,radius:%.2f\n", xValue,yValue,radius); } //check for equality public boolean equals(Object obj) { Circle temp=(Circle)obj; return xValue==temp.getxValue() && yValue==temp.getyValue() &&radius==temp.getRadius(); } //Method makeCopy public void makeCopy(Circle circle) { xValue=circle.getxValue(); yValue=circle.getyValue(); radius=circle.getRadius(); } //Method to get copy public Circle getCopy() { Circle temp=new Circle(); temp.setxValue(xValue); temp.setyValue(yValue); temp.setRadius(radius); return temp; } //Print the circle public void printCircle() { System.out.printf("(%.2f, %.2f) ,radius:%.2f\n", xValue,yValue,radius); } //Return area of circle public double area() { return Math.PI*radius*radius; } //Return the circumference of circle public double circumference() { return 2*Math.PI*radius; } //Return x value public double getxValue() { return xValue; } //set x value public void setxValue(double xValue) { this.xValue = xValue; } //Return y value public double getyValue() { return yValue; } //Set y value public void setyValue(double yValue) { this.yValue = yValue; } }Sample output: myCircle (5.00, 4.00) ,radius:7.23 yourCircle (5.00, 45.00) ,radius:82.20 area of your circle: 21227.24 circumference of your circle: 516.48 myCircle and yourCircle are not equal (6.50, 8.75) ,radius:13.00 myCircle (6.50, 8.75) ,radius:13.00 yourCircle (6.50, 8.75) ,radius:13.00

The center of a circle is a póint in the x-y plane. - Design the class Circle thàt can store the radius and center of the circle. Since the center is a point in the x-y plane , we can use the Point class that we already designed in #1, we must derive the class Circle from the class Point. We should be able to perform the usual operations on a circle, such as setting the radius, printing the radius, calculating and printing the area and circumference, and carrying out the usual operations on the center. The class Circle should contain the following methods and data member: 12. protected member radius 13. default constructor 14. constructor with parameters 15. setCircle(x) 16. getRadius(') 17. setRadius(x ) 18. toString( ) 19. equals(x) 20. makeCopy(x) 21. getCopy(') 22. printCircle( ) 23. area( ) - z• r² 24. circumference( ) - 2 • a • radius
