new java.util.Timer().schedule( new java.util.TimerTask() { @Override public void run() { // your code here } }, 5000 ); EDIT: javadoc says: After the last live reference to a Timer object goes away and all outstanding tasks have completed execution, the timer’s task execution thread terminates gracefully (and becomes subject to garbage collection). However, this can … Read more
If your program doesn’t have a event loop already, use the sched module, which implements a general purpose event scheduler. import sched, time s = sched.scheduler(time.time, time.sleep) def do_something(sc): print(“Doing stuff…”) # do your stuff sc.enter(60, 1, do_something, (sc,)) s.enter(60, 1, do_something, (s,)) s.run() If you’re already using an event loop library like asyncio, trio, … Read more
As I posted in the comment you don’t need to use both setTimeout() and setInterval(), moreover you have a syntax error too (the one extra }). Correct your code like this: (edited to add two functions to force the next/previous image to be shown) <!DOCTYPE html> <html> <head> <title>change picture</title> <script type = “text/javascript”> function … Read more
I have implemented something like this and it works fine: private Timer mTimer1; private TimerTask mTt1; private Handler mTimerHandler = new Handler(); private void stopTimer(){ if(mTimer1 != null){ mTimer1.cancel(); mTimer1.purge(); } } private void startTimer(){ mTimer1 = new Timer(); mTt1 = new TimerTask() { public void run() { mTimerHandler.post(new Runnable() { public void run(){ //TODO … Read more
If you want to simply use Timer, I would do something like this: public class TestClass { public long myLong = 1234; public static void main(String[] args) { final TestClass test = new TestClass(); Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { test.doStuff(); } }, 0, test.myLong); } public void … Read more
According to the Timer documentation, in Java 1.5 onwards, you should prefer the ScheduledThreadPoolExecutor instead. (You may like to create this executor using Executors.newSingleThreadScheduledExecutor() for ease of use; it creates something much like a Timer.) The cool thing is, when you schedule a task (by calling schedule()), it returns a ScheduledFuture object. You can use … Read more
I think this should work: #include <time.h> clock_t start = clock(), diff; ProcessIntenseFunction(); diff = clock() – start; int msec = diff * 1000 / CLOCKS_PER_SEC; printf(“Time taken %d seconds %d milliseconds”, msec/1000, msec%1000);
Don’t use NSTimer that way. NSTimer is normally used to fire a selector at some time interval. It isn’t high precision and isn’t suited to what you want to do. What you want is a High resolution timer class (using NSDate): Output: Total time was: 0.002027 milliseconds Total time was: 0.000002 seconds Total time was: … Read more
Building on the answer from aquinas which can drift and which doesn’t tick exactly on the minute just within one second of the minute: static System.Timers.Timer t; static void Main(string[] args) { t = new System.Timers.Timer(); t.AutoReset = false; t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed); t.Interval = GetInterval(); t.Start(); Console.ReadLine(); } static double GetInterval() { DateTime now … Read more
I checked the source code of CountDownTimer. The “missing tick” comes from a special feature of CountDownTimer that I have not yet seen being documented elsewhere: At the start of every tick, before onTick() is called, the remaining time until the end of the countdown is calculated. If this time is smaller than the countdown … Read more
