This is often perfectly acceptable, but when developing larger applications with many related objects, paying attention to memory concerns can have a huge payoff.
In real life, the flyweight pattern is often implemented only after a program has demonstrated memory problems. It may make sense to design an optimal configuration from the beginning in some situations, but bear in mind that premature optimization is the most effective way of ensuring that your program is too complicated to maintain.
The basic idea behind the flyweight pattern is to ensure ...
