    Java Program to create and display a Circular Linked List

    In this example, we will create a java program of circular linked list and print all the nodes present in the list.

    Program:
    
public class Main {  
public class Node{  
int data;  
Node next;  
public Node(int data) {  
this.data = data;  
}  
}  

public Node head = null;  
public Node tail = null;  

public void add(int data){  
Node newNode = new Node(data);  
if(head == null) {  
head = newNode;  
tail = newNode;  
newNode.next = head;  
}  
else {  
tail.next = newNode;  
tail = newNode;  
tail.next = head;  
}  
}  

public void display() {  
Node current = head;  
if(head == null) {  
System.out.println("List is empty");  
}  
else {  
System.out.println("Nodes of the circular linked list: ");  
do{  
System.out.print(" "+ current.data);  
current = current.next;  
}while(current != head);  
System.out.println();  
}  
}  

public static void main(String[] args) {  
Main cl = new Main();  
cl.add(1);  
cl.add(2);  
cl.add(3);  
cl.add(4);  
cl.display();  
}  
}
    Output:-
    Nodes of the circular linked list:
    1 2 3 4
