Question

This code creates a .txt in the folder directory (it works) but when comes the time to delete the whole directory or the .txt file using delete() method, nothing happens.
The delete() method works only when I replace the .txt file with an ordinary folder

import java.io.*;

public class Filemkdir {
        public static void main(String[] args) throws Exception {
                File f = new File("C:/Temp/Java/secret.txt");


                FileWriter fSecret = new FileWriter(f);
                f.mkdir();

                f.delete();
        }
}

Answer 1

Maybe the fSecret (FileWriter) needs to be closed first. Otherwise the file is “in use”

fSecret.close();
