Closing a stream

[20thCenturyBoy]

Is it safe to attempt to close a stream (eg an InputStream for a Socket) if the stream has already been closed?  Or do I need to check for that possibility?

The documentation doesn't specify, but I would guess that if you call the "close()" method on a Socket, or an InputStream that is already closed, probably nothing will happen - in other words, it won't crash your program or throw an exception.

This would be easy to test in a quick loop.
