El método spliterator() de CopyOnWriteArraySet devuelve un spliterator sobre los elementos de este conjunto en la secuencia adecuada. No hay necesidad de sincronización mientras se opera en el spliterator.
Sintaxis:
public Spliterator spliterator()
Valor devuelto: la función devuelve un divisor sobre los elementos del Conjunto.
Los siguientes programas ilustran la función anterior:
Programa 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));
}
}
Producción:
CopyOnWriteArraySet: [32, 67, 100] Set of Numbers: 32 67 100
Programa 2:
// Java Program to illustrate the CopyOnWriteArraySet
// spliterator() method in Java
import java.util.concurrent.CopyOnWriteArraySet;

// 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));
}
}
Producción:
CopyOnWriteArraySet: [gopal, gfg, jgec, sudo] Set of strings: gopal gfg jgec sudo
