I think both do the same thing.But when we call gc , then also it is not guaranted that this would really remove the garbage objects from the heap releasing memory.

The API documentation of System.gc() says:

The call System.gc() is effectively equivalent to the call:

Runtime.getRuntime().gc()


There's your answer.

From the System.class
Personally I use System.gc(), because this is less code typing

Personally, I never use either -- and neither should you. It's extraordinarily rare that calling one of these methods actually improves an application, and often it has the reverse effect.
