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
