pollLast()
Retrieves
and removes the last element of this deque.
import java.util.*; class DequePollLast{ 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("\nRemoving the Last Element Of the Deque " + myDeque.pollLast()); System.out.println("Elements in the myDeque are " +myDeque); System.out.println("\nRemoving the Last Element Of the Deque " + myDeque.pollLast()); System.out.println("Elements in the myDeque are " +myDeque); System.out.println("\nRemoving the Last Element Of the Deque " + myDeque.pollLast()); System.out.println("Elements in the myDeque are " +myDeque); System.out.println("\nRemoving the Last Element Of the Deque " + myDeque.pollLast()); System.out.println("Elements in the myDeque are " +myDeque); } }
Output
Elements in the myDeque are [10, 20, 30, 40] Removing the Last Element Of the Deque 40 Elements in the myDeque are [10, 20, 30] Removing the Last Element Of the Deque 30 Elements in the myDeque are [10, 20] Removing the Last Element Of the Deque 20 Elements in the myDeque are [10] Removing the Last Element Of the Deque 10 Elements in the myDeque are []
1. return
the tail of this deque, or null if this deque is empty
