class NoteBook

{   

/*This is default constructor. A constructor does   

 * not have a return type and it's name  

  * should exactly match with class name    */   

NoteBook()

{      

     System.out.println("Default constructor");

   }

 public void mymethod()   

{      

          System.out.println("Hello");  

 }  

 public static void main(String args[])

{

/* new keyword creates the object of the class        

 * and invokes constructor to initialize object         */

NoteBook obj = new NoteBook();

obj.mymethod();  

 }
