CleanUpTimerTask.java

import java.util.TimerTask;

public class CleanUpTimerTask extends TimerTask
{
    public void run()
    {
        System.out.println("Clean up files...");
    }
}

TimerDemo.java

import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

public class TimerDemo
{
    public static void main(String[] args)
    {
        TimerTask cleanUpTimerTask = new CleanUpTimerTask();
        Timer timer = new Timer();

        Date firstTime = new Date(System.currentTimeMillis() + 5000);
        System.out.println("firstTime = " + firstTime);

        /*
         * Schedules the specified task for repeated fixed-rate
         * execution, beginning at the specified time.
         *
         * Parameters:
         *
         * task - task to be scheduled.
         *
         * firstTime - First time at which task is to be executed.
         *
         * period - time in milliseconds between successive task
         * executions.
         */
        timer.scheduleAtFixedRate(cleanUpTimerTask, firstTime, 2000);
        System.out.println("Timer has schedule the cleanUpTimerTask...");
    }

}

Output:

firstTime = Sun Jan 20 10:36:17 IST 2019
Timer has schedule the cleanUpTimerTask...
