BufferedOutputStream vs ByteArrayOutputStream

Question

Is there any advantage in wrapping a BufferedOutputStream around a ByteArrayOutputStream instead of just using the ByteArrrayOutputStream by itself?

Answer 1

ByteArrayOutputStream is not recommended if you want to get high performance, but one interesting feature is to send a message with unknown length. For a better comprehension about how these two methods work, see http://java-performance.info/java-io-bytearrayoutputstream/.
