In this exercise, you are going to build on your Circleclass from the previous exercise. You are going to add 2 method, areaDifference and perimeterDifference. Both methods take a doubleradius of a second circle and return the difference from the current circle. For example, if you create a Circle object with a radius of 4 and call areaDifference(3), you will return the diffence between the area of a circle with radius 4 and the area of a circle with a radius of 3. perimeterDifferencewould be the same. Make sure you create at least one Circle and test and print the results of your methods.   given: public class Circle { private double radius; public Circle(double theRadius){ radius = theRadius; } // Add a method called area that returns the area of a circle // using Math.PI public double area() { return Math.PI*radius*radius; } // Add a method called perimeter that returns the perimeter of a // circle using Math.PI public double perimeter() { return Math.PI*2*radius; } }

Question

In this exercise, you are going to build on your Circleclass from the previous exercise.

You are going to add 2 method, areaDifference and perimeterDifference. Both methods take a doubleradius of a second circle and return the difference from the current circle.

For example, if you create a Circle object with a radius of 4 and call areaDifference(3), you will return the diffence between the area of a circle with radius 4 and the area of a circle with a radius of 3. perimeterDifferencewould be the same.

Make sure you create at least one Circle and test and print the results of your methods.

 

given: public class Circle
{
private double radius;

public Circle(double theRadius){
radius = theRadius;
}

// Add a method called area that returns the area of a circle
// using Math.PI
public double area()
{
return Math.PI*radius*radius;
}
// Add a method called perimeter that returns the perimeter of a
// circle using Math.PI
public double perimeter()
{
return Math.PI*2*radius;
}

}
