Closing Streams in Java

by

File handles are scarce, finite resources. You can run out of them if you don’t clean them up properly, just like database connections.

If you’ve written a small program with just one user you can get away with being sloppy and not closing in a finally block.

But if you end up using that idiom in an application that has many users and file handles you might have a problem.

“First we make our habits, then they make us.” I try to apply best practices even when they aren’t necessary.
