How do I close a multithreaded server?

问题

以下是您提供的代码的中文翻译部分：

  1. public class TaskListServer {
  2.     public static List<String> taskList = new ArrayList<>();
  4.     public static String uniqueString(){
  5.         return String.join(", ", taskList);
  6.     }
  8.     public static void addTasks(String task) {
  9.         taskList.add(task);
  10.     }
  12.     public static void main(String[] args) {
  13.         Scanner sc = new Scanner(System.in);
  15.         try {
  17.             ServerSocket serverSocket = new ServerSocket(4242);
  18.             while (true) {
  19.                 Socket clientSocket = serverSocket.accept();
  20.                 ThreadedServer clientThread = new ThreadedServer(clientSocket);
  21.                 new Thread(clientThread).start();
  22.             }
  24.         }catch (IOException e) {
  25.             e.printStackTrace();
  26.         }
  28.         sc.close();
  29.     }
  30. }

So I have a program that clients can enter any type of tasks and other clients can check it as well but I don't know how to close the loop that tries to accept new connetions to the server.
What I want is when I close the last client running using a command I wrote I want the server to close as well.

Can anyone help?

  1. public class TaskListServer {
  2.     public static List&lt;String&gt; taskList = new ArrayList&lt;&gt;();
  4.     public static String uniqueString(){
  5.         return String.join(&quot;, &quot;, taskList);
  6.     }
  8.     public static void addTasks(String task) {
  9.         taskList.add(task);
  10.     }
  12.     public static void main(String[] args) {
  13.         Scanner sc = new Scanner(System.in);
  15.         try {
  17.             ServerSocket serverSocket = new ServerSocket(4242);
  18.             while (true) {
  19.                 Socket clientSocket = serverSocket.accept();
  20.                 ThreadedServer clientThread = new ThreadedServer(clientSocket);
  21.                 new Thread(clientThread).start();
  22.             }
  24.         }catch (IOException e) {
  25.             e.printStackTrace();
  26.         }
  28.         sc.close();
  29.     }

不要使用无限循环（while(true)）。

  1. private static boolean acceptNewClients = true;
  3. public static void flipAcceptNewClients() {
  4.     acceptNewClients = !acceptNewClients;
  5. }
  7. public static void main(String[] args) {
  8.     /* 你的代码在这里 */
  9.     while (acceptNewClients) {
  10.         Socket clientSocket = serverSocket.accept();
  11.         ThreadedServer clientThread = new ThreadedServer(clientSocket);
  12.         new Thread(clientThread).start();
  13.     }
  14.     /* 你的代码在这里 */
  15. }
英文:

Don't use an infinity loop (while(true)).

  1. private static boolean acceptNewClients = true;
  2. 	
  3. 	public static void flipAcceptNewClients() {
  4. 		acceptNewClients = !acceptNewClients;
  5. 	}
  6. 	
  7. 	public static void main(String[] args) {
  8.         /* your code here */
  9. 		while (acceptNewClients) {
  10. 			Socket clientSocket = serverSocket.accept();
  11. 			ThreadedServer clientThread = new ThreadedServer(clientSocket);
  12. 			new Thread(clientThread).start();
  13. 		}
  14.         /* your code here */
  15. 	}
