Java LinkedList - spliterator() Method

The java.util.LinkedList.spliterator() method is used to create a late-binding and fail-fast spliterator over the elements in the list.

Syntax

public Spliterator<E> spliterator()

Here, E is the type of element maintained by the container.

Parameters

No parameter is required.

Return Value

Returns a spliterator over the elements in the list.

Exception

NA.

Example:

In the example below, the java.util.LinkedList.spliterator() method is used to create a spliterator over the elements in the given list.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a LinkedList
    LinkedList<Integer> MyList = new LinkedList<Integer>();

    //populating the LinkedList
    MyList.add(10);
    MyList.add(20);
    MyList.add(30);
    MyList.add(40);
    MyList.add(50);

    //creating spliterator object on the LinkedList 
    Spliterator<Integer> splitr = MyList.spliterator(); 

    //display content of the LinkedList
    //using tryAdvance method
    System.out.print("MyList contains: ");              
    while(splitr.tryAdvance((n) -> System.out.print(n + " ")));   
  }
}

The output of the above code will be:

MyList contains: 10 20 30 40 50

Example:

Lets consider another example to learn the concept of spliterator over the elements in the given list.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a LinkedList
    LinkedList<Integer> MyList = new LinkedList<Integer>();

    //populating the LinkedList
    MyList.add(10);
    MyList.add(20);
    MyList.add(-30);
    MyList.add(-40);
    MyList.add(-50);

    //creating spliterator object on the LinkedList 
    Spliterator<Integer> splitr = MyList.spliterator(); 

    //printing estimateSize of the LinkedList
    System.out.println("Estimated size: " + splitr.estimateSize());  

    //display content of the LinkedList using 
    //forEachRemaining method
    System.out.print("MyList contains: ");               
    splitr.forEachRemaining((n) -> System.out.print(n + " "));
  }
}

The output of the above code will be:

Estimated size: 5
MyList contains: 10 20 -30 -40 -50
