Appendix B. CRC Java Code
B.1. How to execute the crc.java code
To use the class crc.java you must compile the below java code (B.2 Java code of crc.java). After you
can execute the class via the following order :
%JAVA_HOME%\bin\java –cp %DIR% CRC %STREAM%
Where :
• %JAVA_HOME% is the directory where the jdk is installed
• %DIR% is the directory where the class crc.class can be found
• %STREAM% is the input stream used for the CRC calculation
B.2. Java code of crc.java

* Encapsulates CRC computation.

* For reference, the parameters for this implementation, relative to the standard
* parameters for CRC testing as described, for example,
* <a href="http://www.gpfn.sk.ca/~rhg/csc8550s02/crc.html">here</a> or
* <a href="http://rcswww.urz.tu-dresden.de/~sr21/crc.html">here</a> are as follows:
* <ul><li>CRC order: 32</li>
* <li>CRC polynomial: 814141AB</li>
* <li>Initial CRC value: 00000000 (and the direct/non-direct distinction is
* irrelevant).
* </li>
Edition Number: 4.5 41
AIXM PRIMER
* <li>Final XOR value: 00000000 (and the CRC is not reversed before the final XOR).
* </li>
* <li>The check box "Reverse input data bytes" should not be checked. </li>
* </ul>
* With these settings, the CRC calculator at the first web address above agrees on
* the computed CRC for the test data supplied in the ReadMe.doc file supplied by
* Eurocontrol with the original version of this code.
