Constructor Creation.

                                    HOW TO CREATE OBJECT OF CLASS??

1. The operator new is use to create a reference to the class.

2. It allocate's a memory the object of the class.

3. Constructors are used  to create Object of class.
     -It has same name as that of class
4. A default constructor is created by the java compiler during run-time,
       If the coder doesn't define any.
5. Code:
     
class Refer{           // class Refer.
  int a;
  
  Refer(int a){          // Parameterized  Constructor.
    System.out.println(a);
  }
  
    public static void main(String[]abc){

 Refer r = new Refer(10);   //passing value to variable a of Contructor.
 
}

}

6. Constructor is a method which have same name with the class and no return type.

7. Parameterized constructor means a value can passed as argument.
