Interfaces in package

It is possible to declare an interface in a package.
We know that an object cant created to the interface, so we have to implement the interface in a class then we can create object for implementation class.

Let us see a program to declare an interface in the package as follows

package  p;
public interface  A
	void display ( )     // public abstract
import p.A;
public class B implements A
	public void display ( )
		system.out.println("duty is god");
import p.B;
class test
	public static void main ( string args [ ])
		B obj = new B( );
		obj.display( );
