Ok, so I've got a degree in CS and all, but it's been since I earned
that degree that I've ever had to mess with stuff like this. I am
working on someone else's code (this someone is no longer at my
disposal) and have the following method:
public static int get2Little(byte abyte0[], int i) throws Exception
{
return abyte0[i + 1] << 8 & 0xff00 | abyte0[i + 0] & 0xff;
}
Hmm...
First, if you like to memorize stuff, you can remember which gets
evaluated first, "<<" or "&". Most of us have better things to
remember. So I'd sprinkle parentheses all over to clarify.
Second, "abyte0[i + 1]" is a byte, so "abyte0[i + 1] << 8" is also a
byte. But you've shifted all its data out, giving you 0. You need a cast.
Maybe this is what you're after:
public static int get2Little(byte abyte0[], int i)
{
return (((int) abyte0[i + 1]) << 8) | abyte0[i];
}
That might work, unless it trips over an issue with signs. :-)
