Delete files when closing window

[Ash maker]

Hello,
I wish that when I close the window of my program Java, I delete the files that I created. Here is the code for it, which I am being trying.

frame.addWindowListener(new WindowAdapter()
    	{
    	    Public void windowClosing(WindowEvent e)
    	    {
    	    	File val_fl = new File("C: / Documents and Settings/temp/Desktop/val_fl");
    File parm = new File("C: / Documents and Settings/temp/Desktop/parm");
    File dir = new File("C: / Documents and Settings/temp/Desktop/dir");
    val_fl.delete();
    parm.delete();
    dir.delete();
    	    }
    	});

But the following code does not work. Do you have any ideas about it.

Hello,

But the following code does not work. Do you have any ideas about it.

The file is probably still open in your application. At a pinch you could use deleteOnExit () instead.
Caution : Do not use deleteOnExit () On an application server or a large amount of data because there is a risk of memory leak.
Why put these files in the directory of your application?
- Whether it is temporary file, and in this case it is better to use File.createTempFile () to create them.
- Either there is config file, and in this case it is best to create a folder in the home directory of the user

      File fl = new File(System.getProperty("user.home"), . MyApp ");

Hi,
Thank you for your answers, but in fact I use PrintWriter to create my files where I'm going to write.

PrintWriter valfl = new PrintWriter( new FileWriter("valfl"),true );

I have not found a method similar to the one you advised me to "File". The code I gave earlier was a sort of "trickery" in order to erase (but it does not work) Or how to create my files with "File" to use your method deleteonclose () and write to it (without changing all my code. I only use PrintWriter and I use simple "valfl . System.out.println () "to write it

Hello,

You simply pass the file created in your FileWriter, rather than passing the file name

The code I gave earlier was a sort of "trickery" in order to erase (but it does not work )

If this does not work that is that your file is still open. Close your file in your code and then try compiling it. Try this and if you have any problem then do post back.

Hello,
Ok
- It creates and deletes to the end ==> AC is REAL!
BUT
- It no longer writes anything in it .... ==> AC is not cool!
That's what I did:

File vl = new File(System.getProperty("user.home"), "pw");
vl.deleteOnExit();
PrintWriter pw = new PrintWriter(vl);
 
/ / And when I write in:
pw.System.out.println("test");

Why not write anything in it?

Hello,
Even I have a similar kind of a problem, but after some testing and working on the code, I come to knew that I did not close the stream. I had forgot to close the stream in my code. I think even you have did not closed the stream. If you do not know how to then, you have to add

valfl.close();

Try it and I am sure this will work, if not then post back with the error.
