ConcurrentLinkedQueue spliterator() method in Java

The spliterator() method in ConcurrentLinkedQueue class returns a Spliterator over the elements in this queue. Spliterator is a Java 8 interface that is used to traverse and partition elements of a source. It is used to traverse the elements of a collection one by one and perform some operations on each element.

Syntax:

Spliterator<E> spliterator()

Where, - E is the type of elements returned by the Spliterator.

Example:

ConcurrentLinkedQueue<String> queue = new ConcurrentLinkedQueue<>();
queue.add("Java");
queue.add("Python");
queue.add("C++");
queue.add("JavaScript");

Spliterator<String> spliterator = queue.spliterator();
spliterator.forEachRemaining(System.out::println);

Output:

Java
Python
C++
JavaScript

Another example using tryAdvance() method:

ConcurrentLinkedQueue<Integer> queue = new ConcurrentLinkedQueue<>();
queue.add(10);
queue.add(20);
queue.add(30);
queue.add(40);

Spliterator<Integer> spliterator = queue.spliterator();
spliterator.tryAdvance(System.out::println);
spliterator.tryAdvance(System.out::println);

Output:

10
20
