If you are talking about SE then the Timer class might be what you are looking for http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Timer.html, available since Java 5.

If you need to time something in an application server context I would recommend having a look at EJB timers http://www.javabeat.net/2007/03/ejb-3-0-timer-services-an-overview/ available since EJB 3.0.

Alternatively, depending on what you are really trying to do, you could elaborate if using a cron job (or any other OS based timer method) would be more suitable, i.e. you don't want or can't have the VM running all the time.
