Re: programing styles

[Jerzy Puchala <jerzypuc@scdi.com>]

Just for the record - in my experience we will have faster code if we 
also write extra line of code:

private void myproc(Vector vect){
  int z = vect.size();
  //this way we are avoiding function calls every iteration
  for( int i=z; i >= 0; i-- ){
    MyObject obj = (MyObject)vect.elementAt(i);
    //int y = (MyObject)vect.elementAt(i).getY();
    //there we are also avoiding extra function calls
    int y = obj.getY();
  }
}

Now about a subject - I like to have declarations inside the loop.

Best Regards
