E getLast()

Retrieves, but does not remove, the last element of this deque.

import java.util.*;

class DequeGetLast{
 public static void main(String args[]){
  Deque<Integer> myDeque = new LinkedList<Integer> ();
  
  /* Add Elements to the myDeque */
  myDeque.add(10);
  myDeque.add(20);
  myDeque.add(30);
  myDeque.add(40);
  
  System.out.println("Elements in the myDeque are " +myDeque);
  
  System.out.println("\nRetrieving the Last Element Of the Deque " + myDeque.getLast());
  System.out.println("Elements in the myDeque are " +myDeque);
  
  System.out.println("\nRetrieving the Last Element Of the Deque " + myDeque.getLast());
  System.out.println("Elements in the myDeque are " +myDeque);
  
 }
}

Output

Elements in the myDeque are [10, 20, 30, 40]

Retrieving the Last Element Of the Deque 40
Elements in the myDeque are [10, 20, 30, 40]

Retrieving the Last Element Of the Deque 40
Elements in the myDeque are [10, 20, 30, 40]
