Deleting Files

[SSJ]

I'm having problems trying to delete 2 files, since when I try to delete the 2nd the first one isn't yet deleted and so the other delete will fail. I'm using:

Newfile.delete(); //Delete the temporary file
boolean jj = tmpfile.delete();

jj returns false everytime, so I need to wait for the NewFile be actually deleted b4 deleting the other one. I was thinking on something like:

Newfile.delete(); //Delete the temporary file
while (Newfile.exists()) { }
boolean jj = tmpfile.delete();

Any idea on how should I guarantee that the 2nd delete will only be ran after the 1st one was actually done?

From what you say, I take it that in some part of your code, fileOne is created, and then at some point later deleted. If when you delete that fileOne, you set a boolean to that action...

and then you start a Thread within the code, which monitors when that file is deleted :


File fileOne = new File("c:\wherever\fileOne.txt"
//... some other code / methods
boolean bFileOne = fileOne.delete();

//... some other code /methods

File fileTwo = new File("c:\wherever\fileTwo.txt"

//... some other code /methods

Thread thread = new Thread(new Runnable() {
public void run() {
try {
while (!bFileOne) {
;//do nothing
}


fileTwo.delete();

}
catch ( IOException e ) {
System.out.println(e.toString());
}
}
});



This thread will then sit and wait for the first file to be deleted by whatever code section/method

ups this was a mistake of mine... I had another thread that was still using the file when I was trying to delete it that's why I couldn't delete it, but since no exception was raised I didn't even think about it. thanks for the reply anyway.
