Inserting node at beginning of list and print link list data in java

Add a node at the beginning

The new node is always added at the beginning node of the given Linked List. For example if the given Linked List is 50->100->105->220->250 and we add an item 330 at the beginning, then the Linked List becomes 330->50->100->105->220->250

package com.dashzin.linklist;

public class AddFirst {

     Node head;

    

     static class Node{

          int data;

          Node next;

     Node(int data){

          this.data=data;

          next=null;

     }

     }

 /* This method will prints data of linked list starting from head */

     public void printList(){

          while(head!=null){

              System.out.print(head.data+" ");

              head=head.next;

          }

     }

    

     /* Inserts a new Node at front of the list. */

     public void insert(int new_data){

          Node new_node=new Node(new_data); // Allocate the Node & Put the data

          new_node.next=head; //Make next of new Node as head

          head=new_node;  // Move the head to point to new Node

     }

    

     public static void main(String args[]){

         

          // creating four node for linklist

          AddFirst lkl=new AddFirst();

          lkl.head=new Node(1);

         

          Node first=new Node(2);

          Node sec=new Node(3);

          Node third=new Node(4);

         

          //Link all the node with each other.....

         

          lkl.head.next=first;

          first.next=sec;

          sec.next=third;

         

          // calling insert method to insert node at beginning position..

          lkl.insert(5);

         

          //calling method to print_list.....

          lkl.printList();

         

     }

}
