Schedule vs Scheduleatfixedrate

The best way to differentiate between the two is that the timer's revelation time is set to a past time T,scheduleatfixedrate will execute all the tasks from T to now, and schedule will only be timed and executed from now on.

public class Hellomain {    private static int count = 0;    public static void Main (string[] args) {        date date = new Date (System.currenttimemillis ()-n);        Timer timer = new timer ();        SYSTEM.OUT.PRINTLN ("Timer schedule before");        Timer.scheduleatfixedrate (New TimerTask () {            @Override public            void Run () {                count++;                SYSTEM.OUT.PRINTLN (count + "Timer task Run" + calendar.getinstance (). GetTime ());            }        , date, +);        SYSTEM.OUT.PRINTLN ("Timer schedule after");        try {            Thread.Sleep (6000);        } catch (Interruptedexception e) {            e.printstacktrace ();        }        SYSTEM.OUT.PRINTLN ("Timer cancel before");        Timer.cancel ();        SYSTEM.OUT.PRINTLN ("timer cancel after");}    }
