Hi,
I want create a method that receive as input a byte[] and calculate its
crc32. How can I do?
I have found java.util.zip.CRC32 but I'm using JDK 1.3.
Can you halp me?
Thanks

I thought it came out in JDK 1.1.

Anyway, how to use it is documented at
http://mindprod.com/jgloss/crc.html

I have the source code for a CRC-16 posted there. Perhaps you could
generalise it to 32 bit.

I'm unable to see "how you compute a 32-bit CRC using Java' native
method" into mindprod site. I have this message error:
java.lang.ClassNotFoundException:com.mindprod.jdis play.JDisplay.class
Please can you cut and past the code and send me it ?

I did quick look on the net and found a FORTH and an Pascal version.
If you need a Java version, I will translate it for you into Java and
guarantee it gives the same answers as Sun's CRC32 for $50.

you likely don't have your java installed correctly. See

If you are JRE/JDK is not installed properly you are not going to get
very far until you sort that out.

LOL - that was not a bad deal.

If only I could get Roedy to make my CR10 RS232 Communication library in
Java for 50$. I have code in C++ which 'mostly' works.

I wrote a CRC algorithm in C++ once, and could translate it. - <humor> I can
underbid Roedy, but only give 80% guarantee that it will work. </humor>

I do not want to buy null. I will find on the net
