1. Write a program to demonstrates the concept of inheritance for Square subclass. Consider the requirement below:

GeometricFigure class

• GeometricFigure(): The constructor that sets the height, width and

figureType.

• Display(): A concrete method to display all attributes.

Square subclass:

• Square(): The constructor sets height, width and figureType by calling the superclass constructor.
• DetermineArea(): The method calculates an area of a square: [area = height * width] and call the Display() method from its superclass.

2. Modify Question Q4(a)(ii) by adding an interface called Sides with method printSide () and variable of squareSides with the initial value of 4. Create a program which demonstrates the use of interface Sides in the subclass Square based on the requirement below:

Sides interface:

• printSide(): a declaration of method
• Initializes squareSides variable with the given value of 4.

Square subclass:

• Square(): The constructor sets height, width and figureType by calling the superclass constructor.
• DetermineArea( ) : The method calculates an area of a square: [ area =

height * width ].

• printSide(): Print the number of side of the figure squareSides and call the

Display() method from its superclass.
