Singly linked list Examples in Java

A Linked List in Java can be defined as a collection of objects called nodes that are randomly stored in the memory. Each node contains two fields data & address. The last node of the linked list contains the pointer to the null.

Program:

public class Main
{  
Node head; 
static class Node 
{  
int data;  
Node next;  
Node(int d)  
{ 
data = d;  next=null; 
}  
}  
public void display()  
{  
Node n = head;  
while (n != null)  
{  
System.out.print(n.data+" \n");  
n = n.next;  
}  
}  
public static void main(String[] args)  
{  
Main list = new Main();  

list.head       = new Node(100);  
Node second      = new Node(200);  
Node third       = new Node(300);  

list.head.next = second; 
second.next = third; 
list.display();  
}  
}  

Output:-
100
200
300
