a. Design and implement a class called TheRectangle that models a rectangle with its top-left and bottom- right corners points. The TheRectangle class uses two instances of ThePoint class (created in the previous exercise) as its top-left and bottom-right corners points. TheRectangle should contains essential attributes, the basic set of methods b. a constructor that constructs a rectangle with the given its top-left and bottomright corners (tlx, tly, brx, bry) an overloaded constructor that constructs a rectangle with two ThePoint instances a method that calculates the area of the rectangle, a method that calculates distance of the top-left corner from the given TheRectangle instance's top-left corner f. the number of rectangles that are created during the run-time Write a test program that test all the methods defined in the class.
