2、法，使用Java语言在Eclipse环境下设计了使用LZW算法对文件压缩与解压缩的实现程序。用户可以根据自己的需求，使用此程序方便地对文件进行压缩或者解压缩操作。这里压缩的实质是数字变换，在多媒体信息中包含大量冗余的信息，把这些余冗的信息去掉，就是实现了压缩；解压是由于计算机处理的信息是以二进制数的形式表示的，因此压缩软件就是把二进制信息中相同的字符串以特殊字符标记来达到压缩的目的。关键词：压缩；解压缩；LZWAbstract ：withtheincreasing demand of thelargeamountofdata andtheusingtimeofcomputer, compute
