Thumbs up for a fast and accurate answer :)

It says: Given the the variable list represents a reference to a linked list. Define a method called delete, that removes the last node in the list. This is Java

LinkedListDemo.java

import java.util.LinkedList;

public class LinkedListDemo {

   public static void main(String[] args) {
      
       //LinkedList Object Creation
       LinkedList<String> list = new LinkedList<String>();
      
       //Adding elements to the Linked List
       list.add("Sachin");
       list.add("Pointing");
       list.add("Simcox");
       list.add("Dravid");
       list.add("Gangully");
       list.add("Kumble");
       list.add("Ricky");
       list.add("Zaheer");

       //Displaying the Elements in the Linked List
       System.out.println("*** Displaying the Elements in the LinkedList ***");
       System.out.println(list);
      
//Calling the Delete Method by passing the Linked List as argument
       delete(list);
      
       System.out.println("*** After Calling the delete() method ***");
       //Displaying the Elements in the Linked List
       System.out.println(list);
      
       delete(list);
      
       System.out.println("*** After Calling the delete() method ***");
       //Displaying the Elements in the Linked List
       System.out.println(list);

   }

   //This method will remove the last node in the Linked List
   private static void delete(LinkedList<String> list) {
       list.removeLast();

   }

}

Output:

*** Displaying the Elements in the LinkedList ***
[Sachin, Pointing, Simcox, Dravid, Gangully, Kumble, Ricky, Zaheer]
*** After Calling the delete() method ***
[Sachin, Pointing, Simcox, Dravid, Gangully, Kumble, Ricky]
*** After Calling the delete() method ***
[Sachin, Pointing, Simcox, Dravid, Gangully, Kumble]
