Depends on how you implement it: if you have the option to query the
current balance and define that a withraw operation is only allowed
with sufficient funds then you throw an exception.  If OTOH you define
that withdraw will return success then you have a boolean return
value.  Both approaches are legal and feasible.

Kind regards
