I want to delay doing something, along the lines of setting a countdown timer that will "do a thing" after a certain amount of time. I want the rest of my program to keep running while I wait, so I tried making my own Thread that contained a one-minute delay: public class Scratch { private static boolean outOfTime = false; public static void main(String[] args) { Thread countdown = new Thread() { @Override public void run() { try { // wait a while System.out.println("Starting one-minute countdown now..."); Thread.sleep(60 * 1000); // do the thing outOfTime = true; System.out.println("Out of

We have a requirement where in we need to monitor remote JVM details via JMX using a simple servlet application. So things done till now in a standalone application is 1) Creat a JMX connector & get the Memory data --> done 2) We need to constantly monitor & get the records (2.1 > which can be considered as scheduled task at constant delay & insert the records into DB Or 2.2> does the JMX gives the history if yes which MBean to access for the info?). Here I am planning to use an interface to register the domain , followed to it. Have start & stop button from JSP. The functionality been when we

What's the main difference between scheduleAtFixedRate and scheduleWithFixedDelay methods of ScheduledExecutorService ? scheduler.scheduleAtFixedRate(new Runnable() { @Override public void run() { System.out.println("scheduleAtFixedRate: " + new Date()); } }, 1, 3L , SECONDS); scheduler.scheduleWithFixedDelay(new Runnable() { @Override public void run() { System.out.println("scheduleWithFixedDelay: " + new Date()); } }, 1, 3L , SECONDS); they print exact the same time, seems they are executed at exact the same interval. Try adding a Thread.sleep(1000); call within your run() method...

I have a ScheduledExecutorService that times a few different task periodically with scheduleAtFixedRate(Runnable, INIT_DELAY, ACTION_DELAY, TimeUnit.SECONDS); I also have a different Runnable that I'm using with this scheduler. the problem starts when I want to remove one of the tasks from the scheduler. Is there a way to do this? Am I doing the right thing using one scheduler for different tasks? What is the best way to implement this? JB Nizet Simply cancel the future returned by scheduledAtFixedRate() : // Create the scheduler ScheduledExecutorService scheduledExecutorService = Executors

I need to make my RSS Feed reader check the feed every 10 minutes for new posts, and then parse them if there are new ones. I also need to update the UI about every minute. I have read and heard different things from various sources. My current understanding is that I can use ScheduledThreadPoolExecutor to make two scheduled threads, and one of them needs a Handler for updating the UI. I am unsure about what the most efficient use of these classes or TimerTask . I am also very uncertain about where to make subclasses of these. One friend suggested extending TimerTask as an inner class in my
