I suspect that your design needs to be reviewed.

Hi,

You can use, to achieve the macro behavior, a static method.

Java

public class Utils {
   public static void print(String text) {
      // Stuff...
      System.out.println(text);
      // More stuff...
   }
}

And then, is just call it:

Java

Utils.print("OK!");

I hope this has helped you

Best regards:

Java has no pre-processing. However, that does not prevent you using a pre-processor of another (for instance C) programming language.

Not that the pre-processor itself is evil, but the habit to use it can be :-). My 5.
