Traverse the files in the folder (How far can we go Series 2)

How far can we go series (2)

Traverse the files in the specified path. The files and folders must be differentiated.

To record the file name and whether it is a folder, implement a model

 Package  Web. method. file. model;  Public   Class  Filemodel {  //  Is it a folder?      Private   Boolean  Isdirectory;  //  File Name      Private  String filenmae; Public Filemodel ( Boolean  Isdirectory, string filenmae ){  Super  ();  This . Isdirectory = Isdirectory;  This . Filenmae = Filenmae ;}  Public   Boolean  Isdirectory (){  Return  Isdirectory ;} Public   Void Setdirectory ( Boolean  Isdirectory ){  This . Isdirectory = Isdirectory ;}  Public  String getfilenmae (){  Return  Filenmae ;}  Public   Void  Setfilenmae (string filenmae ){  This . Filenmae =Filenmae ;}} 

Traversing folders Java encapsulates the methods for use:

 /**  **  @ Param  String * path Query file path **  @ Return  Map <Boolean, string> Boolean-> true: folder; false: Non-folder, string: file name/folder name  */      Private List <filemodel> Queryallfilename (string path ){  //  Ensure that the path ends with "/" or "\"          If ((! Path. endswith (file. pathseparator) | (! Path. endswith ("\\" ) {Path = Path + File. pathseparator ;}  //  Query path File filepath = New  File (PATH );  //  Path does not exist          If (! Filepath. exists ()){  Return   Null  ;} List <Filemodel> filemodellist = New Arraylist <filemodel> ();  //  PATH is not a folder          If (! Filepath. isdirectory () {filemodel File = New Filemodel ( False  , PATH); filemodellist. Add (File );  Return  Filemodellist ;}  // Get the path name or folder name String [] filenames = Filepath. List ();  For ( Int I = 0; I <filenames. length; I ++ ){  //  Determine whether a folder is used              If (( New File (path + Filenames [I]). isdirectory () {filemodellist. Add (  New Filemodel ( True , Filenames [I]);}  Else  {Filemodellist. Add (  New Filemodel ( False  , Filenames [I]);}  Return  Filemodellist ;}
