1. Assume that we have five classes: Fruit, Apple, Orange, GreenApple, and RedApple. Apple and Orange are both subclasses of Fruit. GreenApple and RedApple are subclasses of Apple class. 3 Marks a. Draw the inheritance hierarchy for all the classes. b. Which of the following assignments are legal, i. Fruit fob1 = new Orange(); ii. Fruit fob2 = new Apple(); iii. Apple aob = new Fruit(); iv. GreenApple gob=new RedApple(); v. Fruit fob3=new GreenApple(); c. From the above statements which are legal, define the static ans dynamic type of the objects. 2. Write the definition of interfaces and classes using the following details: 4 Marks i. Define an interface class Figure that has method area (). ii. Declare a final class field PI(Pl=3.14) inside the class Figure. iii. Create Triangle, Rectangle classes as the subclasses of Figure class. iv. Declare fields side1, side2 in classes Triangle and Rectangle classes v. Implement the method area() in all the subclasses classes Triangle, Rectangle and
