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
