There's even a neater way using annotations! Consider this:

import java.lang.annotation.*;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.PARAMETER)
public @interface Exclude {
    String value() default "";
}

And use Annotation[][] Method.getParameterAnnotations() to detect 
annotations on the parameters of the invoked method.

Then you can write:

public class Test {

       public void secret (int i, @Excluded String userid) {

       }

       public void secret (int i, @Excluded String userid, @Excluded 
String password) {

       }
...
}

Which is easier to write, and less fragile in case you 
add/remove/reorder arguments.
