        System.out.println("Clean up files...");
    }
}

TimerDemo.java

import java.util.Timer;

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

        /*

         * specified delay.
         *
         * Parameters:
         *
         * task - task to be scheduled.
         *
