Re: static and non static

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..
