Right bit Shift Operator In Java

[James Ellis]

I am trying to reverse engineer some PHP. This PHP code does a right bit shift operator on a string variable.

All the right bit shifts I have seen are for integers. Can I perform a right bit shift operator on a String in Java?

I can't imagine what shift on a String variable would make any sense or have any value.

Do you perhaps mean a byte or char variable containing characters?

Java String variables are Unicode, shifting the whole data array a few bits would make a real mess.

It seems I don't need to do this anyway...i misinterpreted the PHP code.

The PHP code does the following:

$bucket=((crc32($key)>>16)&0x7fff) % $this->bucketcount;

...and I thought that crc32 was returning a string...it turns out its returning a number.

Now if I could only find a java CRC32 class that returned a number that matches the results of the PHP crc32 function...

Would you happen to know any java CRC32 classes?

Did you try searching? When I did the one in the JDK was the first hit.
