If you are using instance variables, you would need to syncronize. However
rather try not to use instance variables. As you have pointed out, Java can
only return a single value, but that could be an array or an object
containing many values, see if that can be used to solve your problem.
Try to avoid syncronisation - it slows things down and is also a rich source
of difficult to fix bugs.
