*10.11 (Geometry: 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 getter methods. A data field radius with a getter 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 10.21a). A method contains (Circle2D circle) that returns true if the specified circle is inside this circle (see Figure 10.21b). A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle (see Figure 10.21c). (a) (b)
