Class Adler32java.lang.Object
All Implemented Interfaces: Checksum public class Adler32 extends Object implements ChecksumA class that can be used to compute the Adler-32 checksum of a data stream. An Adler-32 checksum is almost as reliable as a CRC-32 but can be computed much faster. 用于计算数据流的Adler-32校验和的类。Adler-32校验和几乎同CRC-32一样可靠但计算起来更快。
