timer

问题 Just have a look on this block of code: public Reminder() { a[0]=1000; a[1]=3000; a[2]=1000; a[3]=5000; timer = new Timer(); timer.schedule(new RemindTask(),0, a[i]); } ////////////////////// class RemindTask extends TimerTask { public void run() { point =point +arr[i].length(); doc.setCharacterAttributes(0,point+1, textpane.getStyle("Red"), true); i++; } } I want delay to be changed after each task,so the timings are stored in an array. When i++ is preformed(pointer to array),the timings are

问题 I keep getting the error "PipeObject in class PipeObject cannot be applied to given types" public Pipes() { pipes.add(new PipeObject(x1, y1)); pipes.add(new PipeObject(x1 + 200, y2)); pipes.add(new PipeObject(x1 + 400, y3)); } I have an object class that I want to be added to a JPanel by a class that controls the objects and draws 3 instances of it to the screen. It needs to be able to give different values to the object class. My third class is the main() class and should add the class with

问题 In my iOS app, I am using NSTime to invoke a method which takes screenshot of the device screen. I am taking 30 screenshots per second. On simulator its working fine (as the processor of Mac is far more powerful than iPad). But it takes less number of screenshots in actual device. How can I do this? Any reliable alternative for timer? Please help 来源： https://stackoverflow.com/questions/16982374/how-to-take-30-screenshots-in-a-second-in-an-ios-device

问题 I am trying to add a timer a simulation i am working on. At the moment i can get the timer to display in the location i want, however i cant make the numbers clear each other, i.e they all just stack on top of each other slowly creating a solid black mess. I have tried implementing a clf function but it just clears the entire figure. The code for the timer is: HH = 0; MM = 0; SS = 0; timer = sprintf('%02d:%02d:%02d',HH,MM,SS); text(-450,450,timer); %% adjust location of clock in graph using

问题 I have an application which runs a timer to check for idle time and once there is no activity for 10 seconds the application will close.

What i have to do is add 10 seconds on every action of the user on the application. Even if it is mousemove add 10 seconds so tat the application wont close for another 10

问题 I am developing a messaging system and through discussion here: webBrowser.Document.Write() Irregular Performance I decided to rewite some of the core login in my program in Javascript. The demo seen here: http://nathantornquist.com/code/misc/index6.html runs perfectly when you are adding messages from John. As soon as you add a message from Jack, the timer gets messed up and the color of the date on John's messages stop changing. Can anyone see a clear reason why? 回答1: Did you check the
