Hi,

In using Java IO classes, you often wrap lower level input/output stream to a higher level one. For example,



What's the appropriate way of closing the file, do you close the file using
lower.close() or higher.close(), or both?

Thank you.

The "wrapper" classes like BufferedWriter pass the close() call along to the "wrapped" object -- so calling upper.close() automatically calls lower.close() as well.
