Program Plan Intro
Generic method:
- Methods that introduce their own type parameters are called as generic method.
- List of type parameters included inside the angle bracket appears before the method’s return type.
- In generic method, type parameters are allowed to express the dependencies among the types of one or more arguments and its return type.
- The programmers are enabled to specify a single method declaration with a set of related methods.

In Java
Write a non-static method called average that accepts two integer parameters and returns their average as a double value.
Overload the average method in the above such that if three integers are provided as parameters, the method returns the double value of all three.

- In Python: Using class Point that you implemented in assignment 9, implement a class called ThreeDPoint that inherits class Point. The class has (other than the inherited x, and y) another integer named z. Class ThreeDPoint has the following: Default initializer, used to create objects of type ThreeDPoint, by default x, y, and z are set to 1. initializer with three parameters for x, y, and z. set and get methods for z. Override Method __str__, which returns a string that represent the ThreeDPoint (e.g., p = [4,5, 6]).arrow_forwarda) Design and implement a Comparable Java class to represent a Rational number such as3/2. Your class will have the following methods as well as any other methods necessary (setters, getters, etc.). - A constructor that takes all parameters (numerator, denominator), - A function that returns the number of existing Rational objects, - Override the tostring method, - Methods for adding and multiplying Rational objects, - Your methods will throw exceptions if there are problems. b) Write another class to test your Rational class including the exceptions.arrow_forwardImplement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times.
