"A little bit of Java, all night long"...

[SMurf]

Hello,

Recently I've been toying with Java, assessing it largely by porting some of my C programs to it. However, I've now ran into a little problem, and no matter how many showers I take, I can't get Java off me(!).

I tried to port a program that deals with Wave files. Of course, all of the multi-byte numbers in it are little endian, but Java's big endian. Fearing that I may be stuck with a little endian for the rest of my life, I tried constructing this function inside my main class:-

public static int reverseInt(int source)
{
	int dest;

	dest = ((source & 0xFF000000) >> 24) | ((source & 0xFF0000) >> 8) | ((source & 0xFF00) << 8) | ((source & 0xFF) << 24);
	return dest;
}

This seems to work for all but certain numbers, I get strange results sometimes. As I haven't reinstalled my C compiler yet, I can't wallow in the safety of familiarity, so would anyone care to offer assistance?

Have you tried:

	dest = ((source & 0xFF000000) >>> 24) | ((source & 0xFF0000) >>> 8) | ((source & 0xFF00) << 8) | ((source & 0xFF) << 24);

Perfect, swoopy. Didn't know about that operator (>>>).

SMurf, glad it works. I saw a list of operators at the link below, and thought it was worth trying.
