The forEach() method of Java.util.concurrent.LinkedTransferQueue is an in-built function in Java which is used to traverse each element in this queue.
Syntax:
public void forEach(Consumer<E> action)
Parameters: This method takes a parameter action which represents the action to be performed for each element.
Return Value: This method does not returns anything.
Exceptions: This method throws NullPointerException if the specified action is null.
Below program illustrates the forEach() function of LinkedTransferQueue class:
Program 1:
// Java code to illustrate// forEach() method of LinkedTransferQueue  import java.util.concurrent.LinkedTransferQueue;import java.util.*;  public class GFG {    public static void main(String[] args)        throws InterruptedException    {          // Create object of LinkedTransferQueue        LinkedTransferQueue<Integer> LTQ            = new LinkedTransferQueue<Integer>();          // Add numbers to end of LinkedTransferQueue        // using add() method        LTQ.add(6);        LTQ.add(3);        LTQ.add(5);        LTQ.add(15);        LTQ.add(20);          // Prints the Deque        System.out.println("Linked Transfer Queue : "                           + LTQ);          System.out.println("Traversing this Queue : ");          // Traverse this queue using forEach() method        LTQ.forEach((n) -> System.out.println(n));    }} |
Output:
Linked Transfer Queue : [6, 3, 5, 15, 20] Traversing this Queue : 6 3 5 15 20
Program 2:
// Java code to illustrate// forEach() method of LinkedTransferQueue  import java.util.concurrent.LinkedTransferQueue;import java.util.*;  public class GFG {    public static void main(String[] args)        throws InterruptedException    {          // Create object of LinkedTransferQueue        LinkedTransferQueue<String> LTQ            = new LinkedTransferQueue<String>();          // Add numbers to end of LinkedTransferQueue        // using add() method        LTQ.add("Lazyroar");        LTQ.add("Geeks");        LTQ.add("Computer Science");        LTQ.add("Portal");        LTQ.add("Gfg");          // Prints the Deque        System.out.println("Linked Transfer Queue : "                           + LTQ);        System.out.println("Traversing this Queue : ");          // Traverse this queue using forEach() method        LTQ.forEach((n) -> System.out.println(n));    }} |
Output:
Linked Transfer Queue : [Lazyroar, Geeks, Computer Science, Portal, Gfg] Traversing this Queue : Lazyroar Geeks Computer Science Portal Gfg
