a) Define an interface called 'Function' using Java's Generic Types. The interface should have two methods. The first method is compute(), which takes input of type A and produces output (as return-type) of type B. The second method is printName(), which prints the name of its implementing class. [4 marks] b) Define an abstract class called 'AbstractFunction' that implements the Function interface. It should implement printName() method. The method compute() should be defined as abstract. [5 marks] c) Define a class called 'DuplicateFunction' that extends the AbstractFunction class. It should implement the compute() method, which takes a String as input and returns another String by duplicating the input string. [4 marks] d) Define a class called 'RepeatFunction' that extends the AbstractFunction class. It should define two fields, an integer 'count' and a function 'fun' (of type Function). It should implement the compute() method, which repeatedly calls the fun's compute() method for the 'count' number of times. [8 marks] e) Suppose the main() method in a test class is as follows. What is the output? public static void main(String[] args) { } Duplicate Function df = new Duplicate Function (); Repeat Function rf = new Repeat Function (1, df); System.out.println (rf.compute ("Object Orientation")); a) Define an interface called 'Function' using Java's Generic Types.
