中断等待用户输入的线程，然后退出应用程序

我有两个线程正在运行，userInputThread等待用户从命令行输入并interrupterThread试图打断userInputThread启动后1秒。显然你不能中断被阻塞的线程System.in。另一个答案建议关闭System.in with System.in.close()在中断线程之前。但是当我运行以下代码时，userInputThread永远不会被中断，应用程序只是挂起而不关闭。

class InputInterruptionExample {

    private Thread userInputThread;
    private Thread interrupterThread;

    InputInterruptionExample() {
        this.userInputThread = new Thread(new UserInputThread());
        this.interrupterThread = new Thread(new InterrupterThread());
    }

    void startThreads() {
        this.userInputThread.start();
        this.interrupterThread.start();
    }
    private class UserInputThread implements Runnable {
        public void run() {
            try {
                System.out.println("enter your name: ");
                String userInput = (new BufferedReader(new InputStreamReader(System.in))).readLine();
            } catch (IOException e) {
                System.out.println("Oops..somethign went wrong.");
                System.exit(1);
            }
        }
    }
    private class InterrupterThread implements Runnable {
        public void run() {
            try {
                sleep(1000);
                System.out.println("about to interrupt UserInputThread");
                System.in.close();
                userInputThread.interrupt();
                userInputThread.join();
                System.out.println("Successfully interrupted");
            } catch (InterruptedException e) {
            } catch (IOException ex) {
                System.out.println("Oops..somethign went wrong.");
                System.exit(1);
            }
        }
    }
    public static void main(String[] args) {
        InputInterruptionExample exampleApp = new InputInterruptionExample();
        exampleApp.startThreads();
    }
}

已经有类似的了question https://stackoverflow.com/questions/8997310/interrupt-a-thread-waiting-for-user-input，但没有任何明确的答案。

这已经解决了问题：

class InputInterruptionExample {

    private UserInputThread userInputRunnable;
    private Thread userInputThread;
    private Thread interrupterThread;

    InputInterruptionExample() {
        this.userInputRunnable = new UserInputThread();
        this.userInputThread = new Thread(userInputRunnable);
        this.interrupterThread = new Thread(new InterrupterThread());
    }

    void startThreads() {
        this.userInputThread.start();
        this.interrupterThread.start();
    }
    private class UserInputThread implements Runnable {
        private InputStreamReader isr;
        private BufferedReader br;

        UserInputThread() {
            InputStreamReader isr = new InputStreamReader(System.in);
            BufferedReader br = new BufferedReader(isr);
        }

        public void run() {
            try {
                System.out.println("enter your name: ");
                try{
                    String userInput = br.readLine();
                } catch(NullPointerException e) {}
            } catch (IOException e) {
                System.out.println("Oops..somethign went wrong.");
                System.exit(1);
            }
        }
        public void closeBufferdReader() {
            try {
                System.in.close();
            } catch (IOException e) {
                System.out.println("Oops..somethign went wrong in closeBufferdReader() method");
                System.exit(1);
            }
        }
    }
    private class InterrupterThread implements Runnable {
        public void run() {
            try {
                sleep(1000);
                userInputRunnable.closeBufferdReader();                 
                userInputThread.interrupt();
                userInputThread.join();
                System.out.println("Successfully interrupted");
            } catch (InterruptedException e) {}
        }
    }
    public static void main(String[] args) {
        InputInterruptionExample exampleApp = new InputInterruptionExample();
        exampleApp.startThreads();
    }
}

Update:仅当 BufferedReader 以这种方式拆分时才有效：

InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
String userInput = br.readLine();

由于某种原因，当 readLine() 结构被写为 oneliner 时，中断似乎不起作用：

this.userInput = (new BufferedReader(new InputStreamReader(System.in))).readLine();

因此，虽然可以中断分裂的 BufferedReader 结构中的线程，但现在无法读取用户的输入。

如果有人可以展示一种方法，能够在用户没有及时提供任何输入时（当中断器正在睡眠时）获取用户输入以及中断 UserInputThread ，请这样做。
