// Create a ByteBuffer from a byte array
    byte[] bytes = new byte[10];
    ByteBuffer buf = ByteBuffer.wrap(bytes);
    
    // Retrieve bytes between the position and limit
    // (see e160 Putting Bytes into a ByteBuffer)
    bytes = new byte[buf.remaining()];
    buf.get(bytes, 0, bytes.length);
    
    // Retrieve all bytes in the buffer
    buf.clear();
    bytes = new byte[buf.capacity()];
    buf.get(bytes, 0, bytes.length);
