ArrayDeque getLast() Method in Java

The java.util.ArrayDeque.getLast() method in Java is used to retrieve or fetch the last element of the ArrayDeque. In the process, the method does not delete the element from the deque instead it just returns the last element of the deque.

Syntax:

Array_Deque.getLast()

Parameters: The method does not take any parameter.

Return Value: The method returns the last element present in the Deque.

Below programs illustrate the Java.util.ArrayDeque.getLast() method:

Program 1:

// Java code to illustrate getLast() method of ArrayDeque 
import java.util.*; 
  
public class ArrayDequeDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty ArrayDeque 
        ArrayDeque<String> de_que = new ArrayDeque<String>(); 
  
        // Use add() method to add elements into the Deque 
        de_que.add("Welcome"); 
        de_que.add("To"); 
        de_que.add("Geeks"); 
        de_que.add("4"); 
        de_que.add("Geeks"); 
  
        // Displaying the ArrayDeque 
        System.out.println("ArrayDeque: " + de_que); 
  
        // Displaying the Last element 
        System.out.println("The last element is: " + de_que.getLast()); 
    } 
} 

Output:

ArrayDeque: [Welcome, To, Geeks, 4, Geeks]
The last element is: Geeks

Program 2: Adding Integer elements into the Deque.

// Java code to illustrate getLast() method of ArrayDeque 
import java.util.*; 
  
public class ArrayDequeDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty ArrayDeque 
        ArrayDeque<Integer> de_que = new ArrayDeque<Integer>(); 
  
        // Use add() method to add elements into the Deque 
        de_que.add(10); 
        de_que.add(15); 
        de_que.add(30); 
        de_que.add(20); 
        de_que.add(5); 
  
        // Displaying the ArrayDeque 
        System.out.println("ArrayDeque: " + de_que); 
  
        // Displaying the Last element 
        System.out.println("The last element is: " + de_que.getLast()); 
    } 
} 

Output:

ArrayDeque: [10, 15, 30, 20, 5]
The last element is: 5
