Create repeated timer reminders in Java

I want a class that changes its private variables every 2 seconds I know if I do something

import java.util.Timer;
//...
Timer timer;
//...
timer.schedule(new ChangeSomething(),2000);

It will execute changesomething () in 2 seconds. Is there any way to tell it to do something every 2 seconds, or if I put it in changesomething()

timer.schedule(new ChangeSomething(),2000);

Will it work

In the marginal note, timer What exactly did cancel() do?
