Converting 'little endian bytes' to short

Question

i need to convert to bytes in little endian format (low order byte first) into a short. i wrote an algorithm that i thought would solve this problem. it seems to work most of the time, however occassionally it does produce the wrong value. i was hoping someone out there could help me solve this problem
public static short ByteToShort(byte one, byte two)
// little endian format
// remember LO then HO bytes
short result = 0;
result = (short) ((two << 8) + one);
return result;
}

Answer 1

byte one and two are converted to int in the operation (before reconverted to short in the assignment).
We must be extra careful here with possible signed bytes.
public static short ByteToShort(byte one, byte two)
  // little endian format
  // remember LO then HO bytes
  short result = 0;
  result = (short) (((two << 8) & 0xFF00) | (one & 0x00FF));
  return result;
