You want this method System to throw an exception if the String[] is empty?
public void system( ObjectOutputStream output, String cmd []  ) {
   if (cmd.length == 0)
      throw new IllegalArgumentException("Hey! This is an empty array!");
//...rest of your method
}You can choose for yourself which exception type is most appropriate. You can in theory always use the base Exception but is not very specific nor recommended. In this case, I think an existing unchecked exception such as IllegalArgumentException would be the most appropriate.
