The spliterator() method of CopyOnWriteArraySet returns an spliterator over the elements in this Set in proper sequence. There is no need of synchronization while operating on the spliterator.
Syntax:
public Spliterator spliterator()
Return Value: The function returns an spliterator over the elements in the Set.
Below programs illustrate the above function:
Program 1:
// Java Program to illustrate the CopyOnWriteArraySet// spliterator() method in Java  import java.util.concurrent.CopyOnWriteArraySet;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArraySet        CopyOnWriteArraySet<Integer> ArrSet            = new CopyOnWriteArraySet<Integer>();          // Add elements        ArrSet.add(32);        ArrSet.add(67);        ArrSet.add(67);        ArrSet.add(100);          // print CopyOnWriteArraySet        System.out.println("CopyOnWriteArraySet: "                           + ArrSet);          Spliterator<Integer>            numbers = ArrSet.spliterator();          // print result from Spliterator        System.out.println("Set of Numbers:");          // forEachRemaining method of Spliterator        numbers            .forEachRemaining(                (n) -> System.out.println(n));    }} |
Output:
CopyOnWriteArraySet: [32, 67, 100] Set of Numbers: 32 67 100
Program 2:
// Java Program to illustrate the CopyOnWriteArraySet// spliterator() method in Java  import java.util.concurrent.CopyOnWriteArraySet;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArraySet        CopyOnWriteArraySet<String> ArrSet            = new CopyOnWriteArraySet<String>();          // Add elements        ArrSet.add("gopal");        ArrSet.add("gfg");        ArrSet.add("jgec");        ArrSet.add("sudo");          // print CopyOnWriteArraySet        System.out.println("CopyOnWriteArraySet: "                           + ArrSet);          Spliterator<String>            numbers = ArrSet.spliterator();          // print result from Spliterator        System.out.println("Set of strings:");          // forEachRemaining method of Spliterator        numbers            .forEachRemaining(                (n) -> System.out.println(n));    }} |
Output:
CopyOnWriteArraySet: [gopal, gfg, jgec, sudo] Set of strings: gopal gfg jgec sudo
