I have a method that takes an InputStream and reads data from it. I would like to use this method with a ByteBuffer also. Is there a way to wrap a ByteBuffer so it can be accessed as a stream?

Nothing in the JDK, but there are lots of implementations out there, google for ByteBufferInputStream. Basically they wrap one or more ByteBuffers and keep track of an index into them that records how much has already been read. Something like this comes up a lot, but apparently is buggy, see @Mike Houston’s answer for an improved version).
