There are lots of interesting features with Java Timer class.

Timer class can schedule tasks for onetime execution or execution at a periodic interval.To put it in simple words, TimeTask is the task and Timer is the trigger for this. Best Java code snippets using (Showing top 20 results out of 747) tInterval(.) Using JFreeChart to.
In the following example we’re going to create a Web Crawler task and execute it every 200 milliseconds, but the first execution will be delayed by 100 milliseconds. Java Timer and TimeTask work in partnership. Schedule a task at specified time for one-time execution. To create your own schedulable processes, you have to create your own class the extends TimerTask class. It has more methods, but they generally can be grouped as follows: The Timer class uses several flexible methods to make it possible to to schedule a task to be executed at a specific time, for once or for several times with intervals between executions. To stop the timer when it reaches zero, we create a condition to check the countdownStarter value. Now inside the run () method, we print countdownStarter, and decrease its value by one. The n() method have to be implemented by the task itself, as we do here. In Runnable, we create a variable countdownStarter and initialize it with the number in seconds from where we want to start the countdown timer. Returns the scheduled execution time of the most recent actual execution of this task. Timer is a utility class as a facility for Threads to schedule tasks for future execution as a background thread. The TimerTask is just a class build on top of Runnable interface and provides two methods: Both Timer and TimerTask classes have been designed to work together to provide simple scheduling mechanism.
