El método spliterator() de CopyOnWriteArrayList devuelve un spliterator sobre los elementos de esta lista en la secuencia adecuada. No hay necesidad de sincronización mientras se opera en el spliterator.
Sintaxis:
public Spliterator spliterator()
Parámetros: La función no acepta ningún parámetro.
Valor devuelto: la función devuelve un divisor sobre los elementos de la lista.
Los siguientes programas ilustran la función anterior:
Programa 1:
// Java Program to illustrate the CopyOnWriteArrayList
// spliterator() method in Java
import 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));
}
}
Producción:
CopyOnWriteArrayList: [32, 67, 67, 100] list of Numbers: 32 67 67 100
