Is transient allowed with static?

1. Can a variable be transient if it is static?
2. If so, why? As far as I know java.io Object writing routines only write out instance variables, and not class variables. Aren't objects serialized without their static variables?

Very interesting question.

Class variables (static) can be declared as transient, however class variables are not serialized and de-serialized. Only the persistence state of the object will be serialized, class variables will be re-created or intialized when the object is constructed after the de-serialisation process.

I recommend using the keyword transient for class variables, this makes it very clear to the programmer of the class that this variable will not be serialized.
