OBJECT-ORIENTED THINKING Problem Description: The Circle2D Class 1- Define the Circle2D class that contains:  Two double data fields named x and y that specify the center of the circle with getmethods. (5 points)  A data field radius with a get method. (5 points)  A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. (5 points)  A constructor that creates a circle with the specified x, y, and radius. (5 points)  A method getArea() that returns the area of the circle.(5 points)  A method getPerimeter() that returns the perimeter of the circle.(5 points)  A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). (15 points)  A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b).(12.5 points)  A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See Figure (c) below.(12.5 points) Implement the class. 2- Write a test program TestCircle2D.java that creates a Circle2D object:  new Circle2D(2, 2, 5.5)(6 points)  displays its area and perimeter(6 points)  displays the result of c1.contains(3, 3)(6 points)  displays the result of c1.contains(new Circle2D(4, 5, 10.5))(6 points)  displays the result of c1.overlaps(new Circle2D(3, 5, 2.3))(6 points) a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle.
