hy,

I've a simple, maybe stupid question.
How does a "pointer" look like in Java? I've just tried a "*" like in C, but
it didn't work.
Now I'm not sure in which way I can solve my problem.

The task is, that I want to call a procedure, and the parameters shall be
call by reference.
For example, this is my procedure call:
    checkParameter(kosten_pro_liter, liter, kosten, gesamt_km);

The definition of my procedure looks like this:
  public void checkParameter(String strPreisProLiter, String strAnzahlLiter,
    String strPreis, String strGesamtkilometer) {.....}

What can I do so that after the procedure was executed, the parameters have
the value they have been given within the procedure?

thx,
ekim
