thread-sleep

问题 I have read that Thread.sleep() will pause the currently running thread for the time specified after which it goes back to runnable state waiting for it's turn to run. Also, if called from synchronized context, sleep() doesn't release the lock it holds. So I was wondering when it will release the lock. If the thread, put on sleep, never gets the chance to run so it will always keep the lock with itself and then how other threads get to enter synchronized methods/block. I am not sure if I am

If I use Thread.Sleep() it stops the whole application, I just want to stop a single thread. How do I do that? I am using c#. 回答1:

问题 I'm trying to make a GUI timer without using javax.swing.Timer (kind of a strange task), but I am having trouble making it work. It's supposed to sleep the thread for 1 second, add 1 to seconds , and repeat(infinitely). When I run my program, the icon shows up, but the window does not appear. I'm guessing my error is in the Thread.sleep(1000); line or in that area, but I'm not sure why it doesn't work. Is Thread.sleep(millis) not compatible with swing applications? Do I have to multithread?

问题 Like below link, is there java function that thread interrupt asynchronous queue and put in alertable? https://docs.microsoft.com/en-us/windows/desktop/sync/using-a-waitable-timer-with-an-asynchronous-procedure-call I want to make async timer function in java. I checked it works in c++. But I don't know if it is in java. When main thread run and check periodically if there are the async timer fired and run it and going back and run again. That is what i want to do. Of course, when checking

问题 I'm working on a program for snake. So far I have two classes, one for all the logic of the game and the other as a main class to run the game. Here's what I have Snake class: this is all the constants import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.*; public class Snake { // GUI components private JPanel board; private JButton[] snakeBodyPart; private JButton bonusfood; private JTextArea scoreViewer; // Constants private final int SNAKE_RUNNING_SPEED

问题 As it's stated in the upgrade guide, Effects is being replaced by this new Applicative Functor-like thing Cmd . I don't see any trace of a clue as to where Effects.tick might be hiding, or how it could be reimplemented. From the looks of things, Process.sleep might be the right answer, something like Task.perform errorHandler (\x -> x) <| Process.sleep <| 500 * Time.millisecond would allow the process to wait 500 milliseconds before issuing the next message / action. I'm just not sure if this

问题 This question already has answers here : Please explain the output from Thread run() and start() methods (4 answers) Closed 5 years ago . I was working on Threads when a question struck to my mind..If we can directly call run() method with the object of a class like any ordinary method then why do we need to call Thread.start() to call run() method..I tried both the methods as shown and got same result with both of them First attempt by calling run() method directly class Abc extends Thread {

问题 I am new to Java. I tried to write a program to check database status (overloaded or not). CODE: package com.test.service; import java.util.LinkedList; import java.util.List; public class PersonImpl { public PersonService personService; public void InsertPersonDetails(Person person) { if(personService.isOverLoaded()) { try { Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } } else { //pass control to dao } } } Here I will get boolean from isOverLoaded . If

问题 This question already has answers here : How accurate is Thread.sleep? (3 answers) Closed 2 years ago . The TimeUnit.sleep(long timeout) documentation describes its argument thus: timeout - the minimum time to sleep. However, I'm finding that — at least on Windows 7 64-bit with Java 8 update 141 — the thread often sleeps for less than the minimum: public static void main(String[] args) throws InterruptedException { final long from = TimeUnit.MILLISECONDS.toNanos(100); final long to = TimeUnit
