Hi , I want a particular piece code to be executed after 5 minutes. How can I do that using Java?
out.println("<HTML>");
out.println("<head>");
//out.println("<frame>");
out.println("<frameset rows=\"80%, *\" frameborder=\"0\" border=\"0\" framespacing=\"0\">");
out.println("<frame src=\"DataCenterImage.html\" target=\"DisplayFrame\">");
//out.println("Hai");
out.println("<frame src= \"unlock.html\" target=\"DisplayFrame\">");
out.println("</frameset>");
out.println("</head>");
out.println("</HTML>");
I want the above to be excuted after 15 minutes.

You could use:
Thread.sleep(900000); execute code...The sleep() method takes milliseconds as arguments, therefore the huge number for your 15 minutes.
boutta : No, with Thread.sleep you tell the current thread to wait for a given amount of time. You don't need to implement anything. -
In Java 1.5 and above you can use the
java.util.concurrentpackageScheduledExecutorService scheduler = Executors.newSingleThreadedScheduledExecutor(); ScheduledFuture<?> f = scheduler.schedule(new Runnable() { public void run() { //Code to be executed here } }, 15L, TimeUnit.MINUTES);You can cancel the execution thus:
f.cancel(false);oxbow_lakes : Your question says "5 minutes". If it's 15 I'll edit the codeNicolai : I agree that Quartz is overkill. That is why I voted +1 on your answer. I still gave my answer for completeness -
The Quartz framework may also be helpful to you.
From their site:
Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components or EJBs. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.
I have used this a lot for scheduling in different type of applications and have been very happy with it.
oxbow_lakes : Using Quartz is a bit heavy-handed for the answer to "I want to execute X in 5 minutes". I would only consider Quartz if I wanted cron-like execution, missed triggers, stateful execution etc etc
