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
