Best way to close nested streams in Java?

How we close nested streams? Closing all of them? If yes what is the order?

FileOutputStream out = new FileOutputStream("data.txt", true);
PrintWriter pout = new PrintWriter(out);

/* do some I/O */

pout.close();
out.close();

or closing the the out most stream will close all of them.

pout.close(); // Is this enough?

When closing chained streams, you only need to close the outermost stream. Any errors will be propagated up the chain and be caught.

Take a look at here. Probably this question has been asked before.
