LinkedList public Object peekLast() method

• This method is available in package java.util.LinkedList.peekLast().
• This method is used to retrieve the last or ending element of the linked list but does not remove the last element from the list.
• If the list is empty then it will return null.

Syntax:

    public Object peekLast(){
    }

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.

Return value:

The return type of this method is not void that means this method returns last object or element (i.e. It returns the 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 peekLast() 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 peekLast() method it will retrieve last element 
        // without removing the last element from the list  
        System.out.println("The Last Element In The List is:" + list.peekLast());

        //  Updated list Output after implementing peekLast()
        System.out.println("The Updated List after implementing peekLast() 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 peekLast() The list is:[10, 20, 30, 40, 50]
