Java Recursive delete system files

Java program deletes system files or folders

• The delete () method of the file object can only delete files or empty folders
• The listfiles () method of the file object can traverse all files and folders under the folder
• The file Object isdirectory () method determines whether the current object is a folder
• The file Object isfile () method determines whether the current object is a document

Using the above methods can be done to delete the system files, as long as the appropriate path to pass

1  Public Static voidmothd (file file) {2         if(File.isdirectory ()) {3             //kill all of your child files and subdirectories4             //get all sub-files and subdirectories5file[] Files =file.listfiles ();6              for(File f:files) {7                 if(F.isfile ()) {8                     //Delete directly9 System.out.println (F.getname ());Ten F.delete (); One}Else if(F.isdirectory ()) { A                     //continue to see if files and subdirectories are still available - MOTHD (f); -                 } the             } -              -  - File.delete (); +         } -}

Specific code implementation, in addition to seeking non-recursive deletion, seek the help of the great God, after all, recursion too much memory.
