The below java code to create two sets and assign person’s name to them and then perform set union, difference and intersection of the two sets.

Program:

//import java array class from util package

import java.util.Arrays;

//import java linkedlist hash set class from util package

import java.util.LinkedHashSet;

//import the set interface

import java.util.Set;

//class Definition

public class SetOperation {

// main method

public static void main(String[] args) {

/* create linked list hash set Set1 and assign name of person as values */

Set<String> set1 = new LinkedHashSet<>(Arrays.asList("George", "Jim",

"John", "Blake", "Kevin", "Michael"));

/*Create another linked list hash set Set2 and assign name of person as values */

Set<String> set2 = new LinkedHashSet<>(Arrays.asList("George", "Katie","Kevin", "Michelle", "Ryan"));

/* Display the union of the two sets set1 and set2 using addAll function */

Set<String> union = new LinkedHashSet<>(set1);

union.addAll(set2);

// print the union results

System.out.println("Union of the two sets: " + union);

/* Display the difference of the two sets by calling the removeAll function

*/

Set<String> difference = new LinkedHashSet<>(set1);

difference.removeAll(set2);

// print the difference of two sets

System.out.println("Difference of the two sets: " + difference);

// Display the intersection of the two sets

Set<String> intersection = new LinkedHashSet<>();

/*

Check for the elements that are present in set 2 and also present in

* set 1

*/

for (String e : set2) {

if (set1.contains(e))

intersection.add(e);

}

// print the intersection of two sets

System.out.println("Intersection of the two sets: " + intersection);

}

}

Union of the two sets: [George, Jim, John, Blake, Kevin, Michael, Katie, Michelle, Ryan]

Difference of the two sets: [Jim, John, Blake, Michael]

Intersection of the two sets: [George, Kevin]
