Java program for insert node at beginning of circular linked list. Here problem description and other solutions.

// Java Program 
// Insert node at beginning of circular linked list

// Define class of linked list Node
class LinkNode
{
    public int data;

    }
}

        }
    }
    // Display node element of circular linked list
    public void display()
    {
        if (this.head == null)
        {
            System.out.println("Empty Linked List");
        }
        else
        {

                {
                    // Stop iteration
                    return;
                }
            }
        }
    }
    public static void main(String[] args)
