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]
