The forEach() method of LinkedBlockingDeque performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception.
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 LinkedBlockingDeque class:
Example:
// Java Program Demonstrate forEach()// method of LinkedBlockingDeque import java.util.concurrent.LinkedBlockingDeque;import java.util.*; public class GFG { public static void main(String[] args) throws IllegalStateException { // create object of LinkedBlockingDeque LinkedBlockingDeque<Integer> LBD = new LinkedBlockingDeque<Integer>(); // Add numbers to end of LinkedBlockingDeque LBD.add(11); LBD.add(22); LBD.add(33); LBD.add(44); LBD.add(55); LBD.add(66); LBD.add(77); // print deque System.out.println("Linked Blocking Deque: " + LBD); System.out.println("Traversing this Deque: "); // Traverse this queue using forEach() method LBD.forEach((n) -> System.out.println(n)); }} |
Output:
Linked Blocking Deque: [11, 22, 33, 44, 55, 66, 77] Traversing this Deque: 11 22 33 44 55 66 77
Example: 2
// Java Program Demonstrate forEach()// method of LinkedBlockingDeque import java.util.concurrent.LinkedBlockingDeque;import java.util.*; public class GFG { public static void main(String[] args) throws IllegalStateException { // create object of LinkedBlockingDeque LinkedBlockingDeque<String> LBD = new LinkedBlockingDeque<String>(); // Add elements to end of LinkedBlockingDeque LBD.add("Lazyroar"); LBD.add("Gfg"); LBD.add("Geeks"); LBD.add("Computer"); LBD.add("Science"); LBD.add("Portal"); // print deque System.out.println("Linked Blocking Deque: " + LBD); System.out.println("Traversing this deque: "); // Traverse this deque using forEach() method LBD.forEach((n) -> System.out.println(n)); }} |
Output:
Linked Blocking Deque: [Lazyroar, Gfg, Geeks, Computer, Science, Portal] Traversing this deque: Lazyroar Gfg Geeks Computer Science Portal
