Delete files in Java, delete directories and all files under directory

Translated from: http://www.tqcto.com/article/recommend/142.html

Function: Delete all subdirectories and files in a directory and directory

knowledge point: File.delete () used to remove "A file or empty directory" ! So to delete a directory and all the files and subdirectories in it, recursively delete the code example as follows:

 java.io.File;  DeleteDirectory {            dodeleteemptydir (String dir)  {          success =  ( file (dir)). Delete ();          (Success)  {            system.out.println (" successfully deleted empty directory:  " + dir);         }  {             System.out.println ("failed to delete empty directory: "  + dir);         }    }            deletedir (File dir)  {          ( Dir.isdirectory ())  {            string[] children = dir.list ();               ( i=0; i< children.length; i++)  {                  success = deletedir ( file (dir, children[i));                   (!success)  {                       ;                 }            }         }                  dir.delete ();   &Nbsp; }           main (String[] args)  {         dodeleteemptydir ("New_dir1");         String newDir2 =  "New_dir2";          success = deletedir ( file (NEWDIR2));           (Success)  {             System.out.println ("successfully deleted populated directory: " &NBSP;+&NBSP;NEWDIR2);         }  {             system.out.println ("failed to delete populated directory: " &NBSP;+&NBSP;NEWDIR2);        }          }}
