Question

a) Create a class named Rectangle with fields named length, width, area and perimeter.

b) Add a constructor that takes no argument and sets the length and width to 1.

Add methods named setLength(), getLength() that set and return the length respectively.
d) Add methods named setWith(), getWidth() that set and return the width respectively.

e) Add a method computePerimeter(), which computes a and returns rectangle's perimeter.

f) Add a method computeArea() which computes and returns a rectangle's area.

[Hint Area = Lengh x Width ; Perimeter = 2(Length + Width)]


g) Create a class named TestRectangle whose main() method declares two Rectangle objects.

h) Using the setLength() method, assign one Rectangle object a Length of 2.5cm and assign another a Length of 4.5cm.

i) Using the setWidth() method, assign one Rectangle object a width of 1.5cm and assign another a width of 2.5cm.

j) Call computePerimeter() and computeArea() for each rectangle and display the results.
