Is it possible to use Gson as a singleton?

Question

Java

Hello! In all the examples and codes I have seen, the gson object is created directly at the serialization site.
Can it be used as a singleton? To not create every time?
Maybe there are some problems with multithreading, so it needs to be created in the place of direct use?

Answer 1

Can. It does not store internal state. Just make the singleton thread-safe.

Answer 2

I always use it as a static class member. Didn't notice any problems.
