Bitwise operation syntax not recognized?

[Krooger]

Hello, I'm using Eclipse and I wrote this code:

int dataLength = 0;
		Byte[] length = {wavFile[findData], wavFile[findData+1], wavFile[findData+2],wavFile[findData+3]};
		for(int i = 0; i < length.length; i++) {
			dataLength<<8;
			dataLength = dataLength | length[i];
		}

...and my IDE dose not rocognize the the << operation, giving an error.
Everywhere I look it says thats how you do a bitwise leftshift on an int.
Does anyone know why this is not working for me?

What I am trying to so is suppose I have 4 bytes:
00110011 00000000 10101010 00001111

I am trying to create the integer with the bit value
00110011000000001010101000001111

Thank You

errr I guess i would need a long type if i want 4 bytes but still same problem

Never mind i figured it out, I thought it would work alot like:

i++;

but you must use it like this:

myNum = myNum<<8;

That was not clear in all the usage examples i saw
