I've read all about Formatter and tried so many ways but my hey.txt file won't change anyway.
public class foo {
public static void main(String[] args) {
File file = new File("hey.txt");
System.out.println(file.exists());
Formatter formatter;
try {
formatter = new Formatter(file);
formatter.format("%d %s", 5345, "fds59fd");
formatter.flush();
formatter.close();
} catch (Exception e) {
System.out.println("yes");
System.exit(1);
}
}
}
Actually it's because of VSCode. I ran it from cmd and came to answer.
