Hi,

I developed a solution for the Tower of Hanoi problem:

public static void bewege(int h, char quelle, char ablage, char ziel) {     
        if(h > 0){
           bewege(h - 1, quelle, ziel, ablage);
           System.out.println("Move "+ h +" from " + quelle + " to " + ziel);
           bewege(h - 1, ablage, quelle, ziel);
    }
}

It works fine. Now i want to limit the number of slides and throw an exception if a certain limit is reached. I tried it with a counter but it does not work:

class HanoiNK{

    public static void main(String args[]){
            Integer n = Integer.parseInt(args[0]);
            Integer k = Integer.parseInt(args[1]);

            try{
                bewege(k, n, 'A', 'B', 'C');
            }catch(Exception e){
                System.out.println(e);
            }
    }

    public static void bewege(int c, int h, char quelle, char ablage, char ziel) 
    throws Exception{       
        if(h > 0){
            if(counter != 0){
            bewege(c, h - 1, quelle, ziel, ablage);
            c--;
            System.out.println("Move "+ h +" from " + quelle + " to " + ziel);
            bewege(c, h - 1, ablage, quelle, ziel);
            c--;
            }else{  
                throw new Exception("stop sliding");
            }
        }
    }
}

The exception is never thrown. Any ideas?
