StringBuffer : Java Glossary

StringBuffer

allows you to edit Strings. In JDK 1.5+, you should normally use StringBuilder instead which is not thread-safe, but it is quicker.

If you know the precise length of the String you are building in advance, usually you can build it more efficiently with a char[] ca and use new String( ca ) to convert the result.

You can use a ByteArrayStream as a sort of StringBuffer for bytes.
