    Default problem with returning a value

    Hi, I'm new to Java and was just practicing with the codes.
    I've written the following:

    class PWR {
      double a, ret;
      int    e; 
     
     
      double PWR(double a, int e) {
          this.a = a;
          this.e = e;
     
          for (e=e; e>0; e--) {
            ret = ret * a;
          }
     
          if (e==0) {return ret;}
      }
    }

    I use netbeans to program with Java, and he gives me the following error:
    "Missing Return Statement"
    I hava a return statement so I don't understand what the problem is.
    I hope that somebody can help me.

    Default Re: d

    The compiler checks all possible code execution paths.
    What happens if e != 0?
