How to use TimerTask with lambdas?

Question

As you hopefully know you can use lambdas in Java 8, for example to replace anonymous methods.

An example can be seen here of Java 7 vs Java 8:

Runna         


        

Answer 1

I know this is an old post, but for completeness, I wanted to include the wrapper solution posted by Flown:

private static TimerTask wrap(Runnable r) {
  return new TimerTask() {

    @Override
    public void run() {
      r.run();
    }
  };
}

then your call can become:

timer.schedule(wrap(this::checkDirectory), delay);
