The MyRectangle2D class was defined in Exercise 10.12. Write an application that enables the user to specify the location and size of the rectangles and displays whether the two rectangles intersect, as shown in the following figure. Enable the user to point the mouse inside a rectangle and drag it. As the rectangle being dragged, the rectangle center coordinates in the text fields are updated.
