Response to: Question
that's right, you put arguments in the name of the method. Think of it as each argument having a label that is part of the method name. Your java line was correct, although i think you meant to put in a Y before the second location public void setXLocationYLocation(double x, double y) {}

  Thanks, that clears things up a bit.
  
  Would you call the method with multiple arguments the same way--with the arguments inside the method name?
  
  For example, would you call the method
  
  - (void)setXLocation:(double)x yLocation:(double)y
  
  like this
  
  [setXLocation:10 yLocation:20];

  Yeah, that's right, except your method call has no receiver, and it should. So it would have to be
  
  [anObject setXLocation:10 yLocation:20];
  
  when you want to invoke it.

  Allow me to step in here with a related question if I may. Are the tags in the argument list of the declaration, e.g. yLocation, just for readability or do they provide a way of specifying arguments in any order?
