Answer 1

public short bytesToShort(byte[] bytes) {
     return ByteBuffer.wrap(bytes).order(ByteOrder.LITTLE_ENDIAN).getShort();
}

public byte[] shortToBytes(short value) {
    byte[] returnByteArray = new byte[2];
    returnByteArray[0] = (byte) (value & 0xff);
    returnByteArray[1] = (byte) ((value >>> 8) & 0xff);
    return returnByteArray;
}
