Should Java Objects be reused as often as it can be reused ? Or should we reuse it only when they are ‘heavyweight’, ie have OS resources associated with it ?
All old articles on the internet talk about object reuse and object pooling as much as possible, but I have read recent articles that say new Object() is highly optimized now ( 10 instructions ) and Object reuse is not as big a deal as it used to be.
What is the current best practice and how are you people doing it ?
I let the garbage collector do that kind of deciding for me, the only time I’ve hit heap limit with freshly allocated objects was after running a buggy recursive algorithm for a couple of seconds which generated 3 * 27 * 27… new objects as fast as it could.
Do what’s best for readability and encapsulation. Sometimes reusing objects may be useful, but generally you shouldn’t worry about it.
