thread-sleep

问题 I am trying to make my JButton flicker red for this game I am creating. All the solutions on this website suggest using a thread and putting it to sleep or using a timer, however, the pause allays seems to come after the color change Here is my code: Color cb = board[Y1][X1].getBackground(); board[Y1][X1].setBackground(Color.RED); //Pause board[Y1][X1].setBackground(cb); If I put a thread and put it to sleep on line 3 and comment out line 4 the pause will come before the JButton is turned red

问题 This question is not about designs or patterns and which to use. The heart of this question is about what is happening regarding threads and blocking. This example is to apply to any blocking method that is designed to perform the same action continuously. In this case it is a blocking read or write on a networkstream. Is there any appreciable difference behind the scenes as to threading and performance between the methods? My assumption is that each of the methods below creates a thread or

问题 I was putting together a small little demo to take a long running method simulated with a Thread.Sleep() and wanted to add async to easily go from a synchronous process to an async one. Here's the initial code: private void button1_Click(object sender, EventArgs e) { LongProcess(); } private void LongProcess() { for (int i = 0; i < 33; i++) { progressBar1.Value += 3; Thread.Sleep(1000); } progressBar1.Value += 1; } I was thinking I could simply change the Thread.Sleep(1000) into a new Task(()

问题 I'm trying to simulate betting results on a "horse race" by setting JSlider positions within a loop utilizing random numbers. My problem is that, of course, I can't get the GUI to update while the thread is executing, whereby my JSliders do not seem to be racing, they are going from start to finish. I've tried playing around with the code and separating them out into different methods, but I can't get around the single threaded swing issue. Is there a way to force an update or stop the thread

问题 I made an Analog Clock and its working but when a remove the filloval (Background) the seconds hand keep repeating itself and but when i add filloval it is working. but i do not want the background there. Thanks here is the code import java.awt.Color; import java.awt.Font; import java.awt.Graphics; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Locale; import javax.swing.JFrame; import javax.swing.JPanel; public class Clock extends JPanel implements Runnable {

问题 I'm coding this in JavaFX using a FXMLController and the scene builder. I'm currently creating an Instagram "liker" mostly just for practice as I'm a Computer Science major, and I just like coding. My issue is, I have a for loop that "likes" 20 photos for each hashtag, I obviously need a delay or I'd get banned rather quickly. The user can choose the delay, then I randomize this delay so it's not too robotic. The only way I've been able to use this delay is through the thread.sleep method,

问题 Ok so I have been playing with VB.net and brainstorming ways to accomplish launching a thread reliably every 60 seconds reguardless of how long the prior thread took to do it's work. Here is my question. Given the following code: Dim intTemp As Integer intTemp = 2 Do While intTemp > 1 Dim objWriter As New System.IO.StreamWriter("C:\Documents\Visual Studio 2010\Projects\Report\Report\Stream.txt", True) intTemp = intTemp + 1 System.Threading.Thread.Sleep(5000) objWriter.Write(intTemp & " " &
