Java to implement cool dog music temporary cache file conversion to MP3 file method _java

This article describes the Java implementation of Cool dog music temporary cache file conversion to the MP3 file method. Share to everyone for your reference, specific as follows:

Cool dog Temporary cache file, in fact, is the bar MP3 files are downloaded, but the name seems to be renamed through the MD5 algorithm.

Cool Dog Caches the lyrics while caching the files. This program is based on MD5 management of the corresponding lyrics files and cached files, and then change the cache file to the song name +.mp3 format.

Forgive me for taking so long and not knowing the right class name.

 }

The change (string,string) method is used only for testing purposes. Tune a string or something.

The main use of the Changebydir method, the parameters are temporary files folder and Lyrics Files folder
