ArrayBlockingQueue spliterator() method in Java
The spliterator() method of ArrayBlockingQueue return a Spliterator on the elements of ArrayBlockingQueue. The returned iterator is weakly consistent. Spliterator can be used with Streams in Java 8. Spliterator can traverse elements individually and in bulk too.
Syntax:Â
public Spliterator spliterator()
Return Value: This method returns a Spliterator over the elements in ArrayBlockingQueue.
Below programs illustrates spliterator() method of ArrayBlockingQueue class:
Program 1:Â
Java
// Java Program Demonstrate spliterator()// method of ArrayBlockingQueueÂ
import java.util.concurrent.ArrayBlockingQueue;import java.util.*;public class GFG {Â
    public static void main(String[] args)    {        // define capacity of ArrayBlockingQueue        int capacityOfQueue = 7;Â
        // create object of ArrayBlockingQueue        ArrayBlockingQueue<Integer> Queue            = new ArrayBlockingQueue<Integer>(capacityOfQueue);Â
        // Add element to ArrayBlockingQueue        Queue.add(22);        Queue.add(34);        Queue.add(45);        Queue.add(67);Â
        // create Spliterator of Queue        // using spliterator() method        Spliterator<Integer> numbers = Queue.spliterator();Â
        // getExactSize of Spliterator        System.out.println("Size of Spliterator : "                           + numbers.estimateSize());Â
        System.out.println("list of Numbers:");        // forEachRemaining method of Spliterator        numbers.forEachRemaining((n) -> System.out.println(n));    }} |
Output:Â
Size of Spliterator : 4 list of Numbers: 22 34 45 67

Program 2:
Java
// Java Program Demonstrate spliterator()// method of ArrayBlockingQueueÂ
import java.util.concurrent.ArrayBlockingQueue;import java.util.*;public class GFG {Â
    public static void main(String[] args)    {        // define capacity of ArrayBlockingQueue        int capacityOfQueue = 7;Â
        // create object of ArrayBlockingQueue        ArrayBlockingQueue<String> QueueOfStrings            = new ArrayBlockingQueue<String>(capacityOfQueue);Â
        // Add element to ArrayBlockingQueue        QueueOfStrings.add("India");        QueueOfStrings.add("Pakistan");        QueueOfStrings.add("England");        QueueOfStrings.add("China");        QueueOfStrings.add("UAE");        QueueOfStrings.add("Spain");Â
        // create Spliterator of QueueOfStrings        // using spliterator() method        Spliterator<String>            listOfStrings = QueueOfStrings.spliterator();Â
        // getExactSize of Spliterator        System.out.println("Size of Spliterator : "                           + listOfStrings.estimateSize());Â
        System.out.println("list of Country names:");Â
        // forEachRemaining method of Spliterator        listOfStrings.forEachRemaining((str) -> print(str));    }    public static void print(String str)    {        System.out.println("Value = " + str);    }} |
Output:Â
Size of Spliterator : 6 list of Country names: Value = India Value = Pakistan Value = England Value = China Value = UAE Value = Spain
