accessing a variable from "ex"+ i


    Mar 27 2006 | 4:46 pm
    Hello,
    i'm trying to do something which i normally do in flash actionscript very easily but didn't manage to find out how to do it in java, it is easier to show an example:
    private int ex1=1;
    private int ex2=2;
    private int ex3=3;
    private int ex4=4;
    private int ex5=5;
    for(i=1;i VALS[i]="ex"+i;
    }
    my goal is that in the end my VALS array should be like this:
    VALS[1]=1
    VALS[2]=2
    VALS[3]=3
    VALS[4]=4
    VALS[5]=5
    instead i get this:
    VALS[1]=ex1
    VALS[2]=ex2
    VALS[3]=ex3
    VALS[4]=ex4
    VALS[5]=ex5
    how can i make java to interpret the "ex"+i and read the variable "ex1", "ex2"...
    thankx in advance
    Best

      Hi Andre,
      You can't accomplish this in the way you're approaching, due to the
      static nature of Java compilation. Javascript and actionscript are
      very different in this way from Java/C/C++, using dynamic binding at
      runtime. So you'll need to find a different solution (e.g. use an
      array for your ex variables, store values in a hashtable which is
      dynamically resolved at runtime, manually type all the code rather
      than using a for loop, or some other approach).

      Actually, it could probably be achieved using the reflection API, but
      it would be untidy and not very efficient. From the fragment of the
      example given, it's not clear to me why it's necessary to do the
      coding this way.

      hi again,
      thankx for the enlightment, at least now i now that it's not possible. i allways find out a way to go around this but sometimes i just wish it could be possible.
      the example i gave was not a real example, it was just to be simpler for you to help me, so it was easy to go around it...
      best
