Java listing files

Today, I write a music player to retrieve all the available files in the directory.

Package codefans. app. util; import Java. io. file; import Java. io. filenamefilter; import Java. util. arraylist; import Java. util. list; public class fileoperator {private string dirpath; Public fileoperator (string dirpath) {This. dirpath = dirpath ;} /*** get all files in the directory that match the filter * @ Param filter * @ return full path of all files */public list <string> getfilespath (final string filter) {list <string> List = new arraylist <string> (); file = new file (dirpath); string [] files = file. list (New filenamefilter () {public Boolean accept (File Dir, string filename) {If (filename. endswith (filter) return true; return false ;}}); For (string STR: Files) {list. add (this. dirpath + "/" + Str);} return list ;}}
