private and width as protected.

b.Provide the parameterised constructors to Rectangle class.

c.The Rectangle class has a method area that returns int value.

d.Derive the class ThreeDRectangle by adding a protected int attribute height. The ThreeDRectangle overrides the method area of the Rectangle class.

e.ThreeDRectangle has a method volume that returns int value.

[ Hint: area = length * width; volume= length * width*height]
