ArrayDeque removeLast() Method in Java
The Java.util.ArrayDeque.removeLast() method is used to remove the last element of the Deque.
Syntax:
Array_Deque.removeLast()
Parameters: The method does not take any parameters.
Return Value: This method returns the last element of the Deque after removing it.
Exceptions: The method throws NoSuchElementException if the deque is empty.
Below programs illustrate the Java.util.ArrayDeque.removeLast() method:
Program 1:
// Java code to illustrate removeLast()import java.util.*;  public class ArrayDequeDemo {    public static void main(String args[])    {        // Creating an empty ArrayDeque        Deque<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("For");        de_que.add("Geeks");          // Displaying the ArrayDeque        System.out.println("Initial ArrayDeque: " + de_que);          // Removing elements using removeLast() method        de_que.removeLast();        de_que.removeLast();        de_que.removeLast();          // Displaying the ArrayDeque after removal        System.out.println("ArrayDeque after removing "                           + "elements: " + de_que);    }} |
Output:
Initial ArrayDeque: [Welcome, To, Geeks, For, Geeks] ArrayDeque after removing elements: [Welcome, To]
Program 2:
// Java code to illustrate removeLast()import java.util.*;  public class ArrayDequeDemo {    public static void main(String args[])    {        // Creating an empty ArrayDeque        Deque<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("Initial ArrayDeque: " + de_que);          // Removing elements using removeLast() method        de_que.removeLast();        de_que.removeLast();          // Displaying the ArrayDeque after removal        System.out.println("ArrayDeque after removing "                           + "elements: " + de_que);    }} |
Output:
Initial ArrayDeque: [10, 15, 30, 20, 5] ArrayDeque after removing elements: [10, 15, 30]
