When does a stream close if its not closed manually?

Question

I would like to know when does a stream close if its not closed manually. By this I mean, will the stream be closed if the scope of its reference is no more?

I don't think that the JVM spec makes any guarantee about that. You really are supposed to finally close these resources.

When the process ends, the operating system will release all resources associated to it (including memory, file handles, and network sockets).

There are OS facilities to check about open files and streams, such as lsof.
