The time-Dispatch module was used in the recent project development, and Quartz.net was used in. NET development, and then downloaded the Java Quartz module, but it appeared in use java.lang.NoClassDefFoundError Anomalies, and later on-line search found alternative methods

Using the system comes with the timer code as follows:

 Public class extends timertask{    @Override    publicvoid  run () {        System.out.println ( New Date ());}    }
SimpleDateFormat SDF =NewSimpleDateFormat ("Yyyy-mm-dd HH:mm:ss"); Timer Timer=NewTimer (); Try{timer.schedule (NewJavatask (), Sdf.parse ("2015-03-12 11:47:00")); Timer.schedule (NewJavatask (), Sdf.parse ("2015-03-12 11:18:00")); Timer.schedule (NewJavatask (), Sdf.parse ("2015-03-12 11:19:00")); }Catch(ParseException e) {e.printstacktrace (); }        Try{Thread.Sleep (80000); }        Catch(Interruptedexception e) {} timer.cancel ();

Using a third-party class cron4j

 public  class  mytask "implements   Runnable {@Override  public< /span> void   run () {System.out.println ("        Current system time: "+ new   Date ());    System.out.println ( another minute ticked away ... "); }}
New SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");         New MyTask ();         New Scheduler ();        Scheduler.schedule ("5 * * * *", Task);        Scheduler.start ();         Try {            Thread.Sleep (5L * 60L * 1000L);         Catch (interruptedexception e) {            ;        }        Scheduler.stop ();

Record, easy to use later!
