LinkedTransferQueue spliterator() method in Java

Last Updated : 14 Sep, 2018

The java.util.concurrent.LinkedTransferQueue.spliterator() method is an in-built function in Java which returns a weakly uniform Spliterator across the elements of this queue.

Syntax:

LinkedTransferQueue.spliterator()

Parameters: The function does not accept any parameter.

Return Value: The function returns a Spliterator across the elements of this queue.

Below programs illustrate the LinkedTransferQueue.spliterator() method:

Program 1:

// Java Program Demonstrate Spliterator() 
// method of LinkedTransferQueue  
  
import java.util.Spliterator; 
import java.util.concurrent.LinkedTransferQueue; 
  
class LinkedTransferQueueSpliteratorExample1 { 
    public static void main(String[] args) 
    { 
        // Initializing the queue 
        LinkedTransferQueue<String> queue =  
                   new LinkedTransferQueue<String>(); 
  
        // Adding elements to this queue 
        queue.add("Gfg"); 
        queue.add("is"); 
        queue.add("best!!"); 
  
        // spliterator split and iterate 
        // the split parts in parallel 
        Spliterator<String> str = queue.spliterator(); 
  
        // performs the action for each remaining element 
        str.forEachRemaining( 
            (n) -> { 
                String lc = n.toUpperCase(); 
                System.out.println(" Lower case = " + n); 
                System.out.println(" Upper case = " + lc); 
                System.out.println(); 
            }); 
    } 
} 

Output:

Lower case = Gfg
 Upper case = GFG

 Lower case = is
 Upper case = IS

 Lower case = best!!
 Upper case = BEST!!

Program 2:

// Java Program Demonstrate Spliterator() 
// method of LinkedTransferQueue  
  
import java.util.Spliterator; 
import java.util.concurrent.LinkedTransferQueue; 
  
class LinkedTransferQueueSpliteratorExample2 { 
    public static void main(String[] args) 
    { 
        // Initializing the queue 
        LinkedTransferQueue<Character> queue = 
                  new LinkedTransferQueue<Character>(); 
  
        // Adding elements to this queue 
        for (char ch = 'A'; ch <= 'Z'; ch++) { 
            queue.add(ch); 
        } 
  
        // Printing elements in the queue 
        System.out.print("The elements in the queue are : "); 
  
        // spliterator  split and iterate 
        // the split parts in parallel 
        Spliterator<Character> str = queue.spliterator(); 
  
        // if element exists tryAdvance() will perform action 
        while (str.tryAdvance((n) -> System.out.print(n + " "))) 
            ; 
    } 
} 

Output:

The elements in the queue are : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
