LinkedList public Object pollLast() method

• This method is available in package java.util.LinkedList.pollLast().
• This method is used to retrieves the last or ending element of the linked list and removes the last element from the list finally.
• If the list is empty then it will return null.

Syntax:

    public Object pollLast(){
    }

Parameter(s):

In this method, we don’t pass any object as a parameter in the method but it returns the last object from the linked list and then remove the last element from the list.

Return value:

The return type of this method is not void that means this method returns last object or element (i.e. It returns only last element in the list). If the list is empty then it will not give any exception.

Java program to demonstrate example of LinkedList pollLast() method

import java.util.LinkedList;

public class LinkList {
    public static void main(String[] args) {
        LinkedList list = new LinkedList();
        // use add() method to add elements in the list 
        list.add(10);
        list.add(20);
        list.add(30);
        list.add(40);
        list.add(50);

        //  Current list Output
        System.out.println("The Current list is:" + list);

        //  Using pollLast() method it will retrieve last element 
        // with removing the last element from the list  
        System.out.println("The Last Element In The List is:" + list.pollLast());

        //  Updated list Output after implementing pollLast()
        System.out.println("The Updated List after implementing pollLast() The list is:" + list);
    }
}

Output

D:\Programs>javac LinkList.java

D:\Programs>java LinkList
The Current list is:[10, 20, 30, 40, 50]
The Last Element In The List is:50
The Updated List after implementing pollLast() The list is:[10, 20, 30, 40]
