Java 1.1

This class implements the Checksum interface and computes a checksum on a stream of data using the Adler-32 algorithm. This algorithm is significantly faster than the CRC-32 algorithm and is almost as reliable. The CheckedInputStream and CheckedOutputStream classes provide a higher-level interface to computing checksums on streams of data.
