Output:

The value that needs to be removed is : E  The final deque is :   W  E  B  S  I  T

Example 3

  import java.util.ArrayDeque;  import java.util.Deque;  public class JavaDequeremoveLastExample3 {      public static void main(String[] args) {      Deque<Float> deque = new ArrayDeque<>();         deque.offer(55.9F);         deque.offer(22.5f);         deque.offer(77f);         deque.offer(98.7f);     Float  val = deque.removeLast();     System.out.println(“The value that needs to be removed is : “+val);      System.out.println(“The final deque is : “);      for (Float float1 : deque) {  System.out.println(float1);  }     }  }  

Test it Now

Output:

The value that needs to be removed is : 98.7  The final deque is :   55.9  22.5  77.0
