Gets byte array from a ByteBuffer in java

Question

Is this the recommended way to get the bytes from the ByteBuffer

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()]
bb.get(b, 0, b.length);

Answer 1

This is a simple way to get a byte[], but part of the point of using a ByteBuffer is avoiding having to create a byte[]. Perhaps you can get whatever you wanted to get from the byte[] directly from the ByteBuffer.
