What does the method addLast(E e) do in java?

The addLast(E e) method of the java.util.LinkedList class inserts the specified element at the end of this list.

Example:

import java.util.*;

public class LinkedListDemo {
   public static void main(String[] args) {
      LinkedList list = new LinkedList();
      list.add("Hello");
      list.add(2);
      list.add("Chocolate");
      list.add("10");
      System.out.println("LinkedList:" + list);
      list.addLast("Element");
      System.out.println("LinkedList:" + list);
   }
}

Output:

LinkedList:[Hello, 2, Chocolate, 10]
LinkedList:[Hello, 2, Chocolate, 10, Element]
