Last update on December 21 2024 09:56:30 (UTC/GMT +8 hours)

Write a Java program to insert some elements at the specified position into a linked list.

Sample Solution:-

Java Code:

import java.util.LinkedList;
public class Exercise9 {
 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");

  // print original list
  System.out.println("Original linked list:" + l_list);

  // create a new collection and add some elements

  LinkedList <String> new_l_list = new LinkedList <String> ();
  new_l_list.add("White");
  new_l_list.add("Pink");

  // Add the collection in the second position of the existing linked list
  l_list.addAll(1, new_l_list);

  // print the new list
  System.out.println("LinkedList:" + l_list);
 }
}

Sample Output:

Original linked list:[Red, Green, Black]                               
LinkedList:[Red, White, Pink, Green, Black]
