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 the 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(PI=3.14) inside the class Figure. iii. Create Triangle, Rectangle classes as the subclasses of Figure class. iv. Declare fields side1, side2 in the Triangle and Rectangle classes v. Implement the method area() in all the subclasses classes Triangle, Rectangle and.

3. Assume that we have 4 classes (One, Two, Three and Four) and variables of each of these classes are: One oneob; Two twoob; Three threeob; Four fourob; The following assignments are all legal: oneob = fourob; oneob = threeob; twoob = fourob; The following assignments are illegal: twoob = oneob; twoob = threeob; threeob = twoob; Draw the class diagram to show relationship between One, Two, Three and Four based on Given legal and illegal assignments. (Hint: Use Subtype/Supertype concept)
