JAVA LANGUAGE (8) Instance method isEqual that accepts a parameter aSet of type Set.The method will return true, if aSet is equal to "this object", else it will returnfalse. Two sets are equal, if they contain the same elements in any order.Ex: Let A and B be two sets;A= {7, 4, 20, 15, 12}, B = {4, 7, 12, 15, 20}. As sets A and B contain sameelements, but in different order, therefore, they are equal.(9) Instance method union having a parameter aSet of type Set. Themethod finds the union of aSet with "this object" and returns the result as anobject of type Set.Ex: Let A = {10, 4, 20, 15, 12, 18}, B = {8, 10, 25, 15, 20},C= AUB = {10, 4, 20, 15, 12, 18, 8, 25}(10) Instance method intersection having a parameter aSet of typeSet. The method finds the intersection of aSet with "this object" and returnsthe result as an object of type Set.Ex: Let A = {10, 4, 20, 15, 12, 18), B = {8, 10, 25, 15, 20},C= ANB = {10, 20, 15).(11)Instance method called print() to print all the elements of the set.(B) Write a class called SetApplication having only main method. Createobjects of class type Set using different constructors and call methods of classSet to test all functionalities of class Set. It is required to develop an application in Java to represent Set as a data structureusing Java built-in class ArrayList.(A)Write a class called Set to represent a set as an ArrayList and implementvarious set operations by using methods of class ArrayList. Assume thatthe elements of the set are integers.This class will have the following instance variables: (a) an ArrayList objectcalled list of type Integer, (b) length: the actual number of elements inthe list.This class will have the following methods:(1) Constructor without any parameter (default constructor), which uses adefault value of 10 as capacity, creates ArrayList object list andinitializes length to 0.(2) Constructor with parameter cap for capacity of the list. CreateArrayList object list of capacity equal to parameter cap and initializelength 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 oftype int. It will insert the element in the list at the end and alsoincrement length by one.(6) Instance method isMember that accepts a parameter element of typeint. 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. IfaSet 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.%3D

Two sets are equal, if they contain the same elements in any order. Ex: Let A and B be two sets; A = {7, 4, 20, 15, 12}, B = {4, 7, 12, 15, 20}.

The method finds the union of aset with "this object" and returns the result as an object of type Set. Ex: Let A = (10, 4, 20, 15, 12, 18}), B = {8, 10, 25, 15, 20}, C= AUB = {10, 4, 20, 15, 12, 18, 8, 25} (10) Instance method intersection having a parameter aSet of type Set.
