Now it is customary to write JS code using EditPlus to write code, but each time it is automatically generated editplus a temporary file. bak, looking at all the uncomfortable, so simply write a delete program, when using EditPlus edit the completion of the code, double-click the jar file is much more convenient.

A simple program that contains a few small processes for packaging a release jar file:

1. New Project Deletebakfiles

2. Create a project package Com.susheng.deletebakfiles

3. Package the new class Maindelete type code

The code is as follows:

Package Com.susheng.deletebakfiles;import Java.io.file;//import Javax.swing.joptionpane;import Javax.swing.joptionpane;import Com.susheng.deletebakfiles.util.getcurpath;public class MainDelete {// Recursively deletes all files under the specified path public static void Deletebak (file file) {  if (File.isfile ()) {if (File.getabsolutepath ())  . EndsWith (". bak"))  {//joptionpane.showmessagedialog (null, File.getabsolutepath (), "Current Path", Joptionpane.information_message);        File.delete ();  }  }  else  {     file[] files = file.listfiles ();     for (file f:files)     {        deletebak (f);//recursive deletion of each file     }   }}public static void Main (string[] args) { Getcurpath path = new Getcurpath (); String FilePath = Path.getcurpath (); File File = new file (filePath);d eletebak (file); Joptionpane.showmessagedialog (null, "Delete succeeded", "current Path", Joptionpane.information_message);}}

4. New package Com.susheng.deletebakfiles.util New class Getcurpath

Type the code

Package Com.susheng.deletebakfiles.util;import Javax.swing.joptionpane;public class Getcurpath {public    String Getcurpath ()    {          joptionpane.showmessagedialog (null, System.getproperty ("User.dir"), "Current Path", Joptionpane.information_message);  System.out.println (System.getproperty ("User.dir"));  Return System.getproperty ("User.dir");}    }

5. Package into a JAR package release:

Select Eclispe---Export--java--jar then always next select Output Directory Ok

The project code and the jar package are downloaded here:

Using the method, place the jar file under the bin under the folder you want to delete, double-click to run

Pop-up box to prompt the current path:

Delete again, wait for delete to complete
