Project: The Circle2D Class
Define the Circle2D class that contains:
· Two double data fields named x and y that specify the center of the circle with get methods.
· A data field radius with a get method.
· A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius.
· A constructor that creates a circle with the specified x, y, and radius.
· A method getArea() that returns the area of the circle.
· A method getPerimeter() that returns the perimeter of the circle.
· A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a).
· A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b).
· A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below.
(a) (b) (c)
(a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle.
Draw the UML diagram for the class. Implement the class. Write a test program that creates a Circle2D object c1 (new Circle2D(2, 2, 5.5)), displays its area and perimeter, and displays the result of c1.contains(3, 3), c1.contains(new Circle2D(4, 5, 10.5)), and c1.overlaps(new Circle2D(3, 5, 2.3)).
