It is required to develop an application in Java to represent Set as a data structure using Java built-in class ArrayList. (A) Write a class called Setto represent a set as an ArrayList and implement various set operations by using methods of class ArrayList. Assume that the elements of the set are integers. This class will have the following instance variables: (a) an ArrayList object called list of type Integer, (b) length: the actual number of elements in the list. This class will have the following methods: (1) Constructor without any parameter (default constructor), which uses a default value of 10 as capacity, creates ArrayList object list and initializes length to 0. (2) Constructor with parameter cap for capacity of the list. Create ArrayList object list of capacity equal to parameter cap and initialize length to 0. (3) Instance method getLength, that returns length. (4) Instance method isEmpty to determine whether the set is empty or not. (5) Instance method addelement that accepts a parameter element of type int. It will insert the element in the list at the end and also increment length by one. (6) Instance method isMember that accepts a parameter element of type int. If element exists in the list, it will return true, else it will return false. (7) Instance method subset that accepts a parameter aset of type Set. If aSet is a subset of "this object", it will return true, else it will return false. Ex: Let A and B be two sets; A = {7,4, 20, 15, 12}, B = {12,15}. As all elements of B are contained in A, therefore, B is a subset of A.
