    public static void main(String[] args) throws FileNotFoundException {
        String name = "Your name";  // change it to your name
        File file = new File("name.txt");
        // write name to file
        PrintWriter pw = new PrintWriter(file);
        pw.println(name);
        pw.close();
        // read name from file and print it
        Scanner fin = new Scanner(file);
        System.out.println(fin.nextLine());
        fin.close();
    }
