If you have a reference to a buffered output stream, and you call
close(), will flush() automatically be called?

If you have a reference to a buffered output stream, and you call
close(), will flush() automatically be called?

Yes. (This behavior is inherited from FilterOutputStream.)

What you /cannot/ assume is that program shutdown and or finalize() will
do this.

Read the docs. BufferedOutputStream extends FilterOutputStream.

"close

public void close()
throws IOException

Closes this output stream and releases any system resources
associated with the stream.

The close method of FilterOutputStream calls its flush method, and
then calls the close method of its underlying output stream. "
