The spliterator() method of CopyOnWriteArrayList returns an spliterator over the elements in this list in proper sequence. There is no need of synchronization while operating on the spliterator.
Syntax:
public Spliterator spliterator()
Parameters: The function does not accept any parameters.
Return Value: The function returns an spliterator over the elements in the list.
Below programs illustrate the above function:
Program 1:
// Java Program to illustrate the CopyOnWriteArrayList// spliterator() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArrayList        CopyOnWriteArrayList<Integer> ArrLis            = new CopyOnWriteArrayList<Integer>();          // Add elements        ArrLis.add(32);        ArrLis.add(67);        ArrLis.add(67);        ArrLis.add(100);          // print CopyOnWriteArrayList        System.out.println("CopyOnWriteArrayList: " + ArrLis);          Spliterator<Integer> numbers = ArrLis.spliterator();          // print result from Spliterator        System.out.println("list of Numbers:");          // forEachRemaining method of Spliterator        numbers.forEachRemaining((n) -> System.out.println(n));    }} |
Output:
CopyOnWriteArrayList: [32, 67, 67, 100] list of Numbers: 32 67 67 100
Program 2:
// Java Program to illustrate the CopyOnWriteArrayList// spliterator() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArrayList        CopyOnWriteArrayList<String> ArrLis            = new CopyOnWriteArrayList<String>();          // Add elements        ArrLis.add("gopal");        ArrLis.add("gfg");        ArrLis.add("jgec");        ArrLis.add("sudo");          // print CopyOnWriteArrayList        System.out.println("CopyOnWriteArrayList: " + ArrLis);          Spliterator<String> numbers = ArrLis.spliterator();          // print result from Spliterator        System.out.println("list of strings:");          // forEachRemaining method of Spliterator        numbers.forEachRemaining((n) -> System.out.println(n));    }} |
Output:
CopyOnWriteArrayList: [gopal, gfg, jgec, sudo] list of strings: gopal gfg jgec sudo
