We all know that we should rather reuse a JDBC PreparedStatement than creating a new instance within a loop.

But how to deal with PreparedStatement reuse between different method invocations? Does the reuse-"rule" still count?

Should I really consider using a field for the PreparedStatement or should I close and re-create the prepared statement in every invocation? (Of course an instance of such a class would be bound to a Connection which might be a disadvantage)

I am aware that the ideal answer might be "it depends".
But I am looking for a best practice for less experienced developers that they will do the right choice in most of the cases.
