Program Plan Intro

Program:

//import util package

import java.util.*;

//class definition

public class Test {

// main method

public static void main(String[] args) {

//Create a new Set set1 ofLinkedHash Set type

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

/* add NewYork element into the set using the add() method */

set1.add("New York");

/*Create a new set set2 which equals set1 */

LinkedHashSet<String> set2 = set1;

//clone set1 and assign it a new set set2

LinkedHashSet<String> set3 =

(LinkedHashSet<String>)(set1.clone());

//add Atlanta to the set1

set1.add("Atlanta");

//print each set

System.out.println("set1 is " + set1);

System.out.println("set2 is " + set2);

System.out.println("set3 is " + set3);

/* Print each element present in set 1 using the ForEach() method */

set1.forEach(e -> System.out.print(e + " "));
