timertask

I have a implemented a listener that notifies if we receive a new file in a particular directory. This is implemented by polling and using a TimerTask. Now the program is so set up that once it receives a new file it calls another java program that opens the file and validates whether it is the correct file. My problem is that since the polling happens a specified number of seconds later there can arise a case in which a file is being copied in that directory and hence is locked by windows. This throws an IOException since the other java program that tries to open it for validation cannot (

I have a method and I want it to be scheduled for execution in later times. The scheduling time and method's arguments depend on user inputs. I already have tried Timers, but I have a question. How could It be possible to pass arguments to Java TimerTask run method ? TimerTask timert = new TimerTask() { @Override public void run() { //do something } } sethu You will need to extend the TimerTask and create a constructor and/or setter fields.. Then set the values you want before scheduling the TimerTask for execution. You can write you own class which extends from TimerTask class and you can

So I wanted to try out something for a bit with the Timer and TimerTask classes. I was able to get a line of code to execute after 30 seconds elapsed. What I've been trying to do now is to get this line of code to execute for 5 minuets. This is what I originally tried public static void main(String[] args) { for ( int i = 0; i <= 10; i ++ ) { Timer timer = new Timer(); timer.schedule( new TimerTask() { public void run() { System.out.println("30 Seconds Later"); } }, 30000 ); } } I used the number 10 in the for loop to see if the timer.schedule would wait for another 30 seconds during the next

I need a Timer that basicaly does something every t seconds. But I want to be able to modify the timer period at which the timer repeats the task. I wrote something like this: public Bot() { timer = new Timer(); timer.schedule(new Task(), 1000, moveTime = 1000); } public class Task extends TimerTask { @Override public void run() { System.out.println("Time Passed from last repeat:" + movetime) moveTime += 1000; } So, After 1000ms delay the timer starts and repeats every moveTime ms. The problem is even if I increased movetime by 1000, the timer always runs at initial delay(1000) but the value

In my Android application, I run a timer and cancel it on some other event: class MyTimerTask extends TimerTask { override boolean cancel() { ... } override void run() { ... } } ... Timer t = new Timer(); t.schedule(new MyTimerTask(),...) ... t.cancel(); I was expecting t.cancel() to automatically invoke MyTimerTask 's cancel() method. But that method is never invoked. I am wondering what exactly is the different between these two methods and why the second method does not get called automatically. I think you meant to call cancel() on your instance of MyTimerTask Read the docs for this method
