(This exercise should be used in conjunction with Exercises 1 and 3.) Write a definition for a

Rectangle

class. Provide two

Point

instance variables,

topLeft

and

bottomRight,

which establish the top-left and bottom-right corners of the rectangle, respectively. Provide a two-parameter constructor that initializes

topLeft

and

bottomRight.

Provide a

shiftRight

method that shifts the rectangle in the x direction by the value of the method’s

double

parameter,

shiftAmount.

Provide a

shiftUp

method that shifts the rectangle in the y direction by the value of the method’s double parameter,

shiftAmount.

Make each of these methods return values that enable chaining. Provide a

printCenter

method that displays the x and y values of the center of the rectangle.
