// Create a byte array
byte[] bytes = new byte[10];
// Wrap a byte array into a buffer
ByteBuffer buf = ByteBuffer.wrap(bytes);
// Retrieve bytes between the position and limit
// (see Putting Bytes into a ByteBuffer)
bytes = new byte[buf.remaining()];
// transfer bytes from this buffer into the given destination array
buf.get(bytes, 0, bytes.length);
// Retrieve all bytes in the buffer
buf.clear();
bytes = new byte[buf.capacity()];
// transfer bytes from this buffer into the given destination array
buf.get(bytes, 0, bytes.length);
byte[] bytes = new byte[10];
