8. Insert at End

Write a Java program to insert the specified element at the end of a linked list.

Sample Solution:-

Java Code:

import java.util.LinkedList;
  public class Exercise8 {
  public static void main(String[] args) {
   // create an empty linked list
     LinkedList<String> l_list = new LinkedList<String>();
   // use add() method to add values in the linked list
          l_list.add("Red");
          l_list.add("Green");
          l_list.add("Black");
     System.out.println("Original linked list:" + l_list);    
  // Add an element at the end of a linked list
     l_list.offerLast("Pink");
     System.out.println("Final linked list:" + l_list);  
 }
}

Sample Output:

Original linked list:[Red, Green, Black]                               
Final linked list:[Red, Green, Black, Pink]
