difference between creating an object with class and interface reference in java

//Interface Inn

package com.saa.com;

    public interface Inn {

    public void display();

    }

//class A

package com.saa.com;

 public class A implements Inn{

@Override

public void display() {

System.out.println("====A display====");

}

public void a_display(){

System.out.println("====Non Interface method display====");

}

}

// class B

package com.saa.com;

public class B implements Inn{

@Override

public void display() {

// TODO Auto-generated method stub

System.out.println("====B display====");

}

}

//Class C

package com.saa.com;

public class C {

public static void main(String[] args) {

// TODO Auto-generated method stub

/* An interface reference can point

to any object of a class that implements this interface*/

//case 1:

A a=new A();

a.display();

a.a_display(); // non interface method.

//output  :  ====A display====

/* Exp: In the above code we defined reference variable "a" as A class type,

   in order to call display() method which A class implemented.*/

//case 2: Now if we want to use display method in B class we will do following code

B b=new B();

b.display();

//output     :  ====B display====

/*   Exp: In the above code we defined reference variable "b" as B class type,

    in order to call display() method which B class implemented. */

Inn i=new A(); //new B() to access B class display()

i.display();

/*i.a_display(); this gives an error, since interface reference cannot

point to non interface methods*/

//output  :  ====A display====

/* Exp: The above code states that object of "A" class was stored in "i" variable

 which is of "Inn" interface type. Since A implements Inn, so Inn type variables

 can call all methods in that Interface. 

 

 So display() which belongs to Inn and implemented by A class can be accessed 

 by "i" varable. 

 this results i.display() to give output "====A display====".

in case2:

 Now if I want to access display() in B implementation we simple need

 TO CHANGE ONLY ONE LINE " ie OBJECT CREATION"

 Inn i= new B();

i.display();

//output  :  ====B display====

 */

   

/*Now we can state that "Inn" Interface reference "i" is going point any

class object "A" or "B" that implements "Inn"

NOTE: AN INTERFACE REFERENCE CANNOT POINT TO NON INTERFACE METHODS IN A CLASS
