(All numbers should be of type double)
Create a class called Circle.
It should have an instance field called radius.
It should have another instance field named center of type Point.
It should have a get and a set for radius.
It should have get and set methods for the center. Those methods should use the Point class.
It should have a getArea method that returns the area of the circle.
It should have a three-arg constructor with arguments radius, x, and y.
It should have a two-arg constructor, with arguments radius, and center.
It should have a one-arg constructor with an argument of type Circle that duplicates its argument.
It should have a toString method that returns a string like “Circle, radius=4, center= (4,6)”
It should have an equals method that compares two circles and returns true if the argument circle has
the same radius and location. Extra credit: make it return true if all three numbers are within 1/100 of
one percent of being equal.
Now create the class for the type Point.
This class should have two instance fields called x and y.
Both instance fields should have get and set methods.
The class should have a two-arg constructor.
There should also be a no-arg method getDistance, which returns the distance from the point (0,0) to
(x,y).
The method getDistance should have a one-arg overload, which accepts a point as its argument, and
returns the distance between the argument point and the instance point.
Now in your main program should be in a class called TestCircle. In it, create a circle of radius 5
centered at (4,6).
Use the one-arg constructor to make a copy of this circle. Modify the second circle to have a center at
(-2.5, 7). Use the GetDistance method to calculate the distance between the two circles.
Submit the .java files for classes Circle, Point, and TestCircle to the drop box by midnight, Tuesday,
