java - 中断线程后执行操作

Question

我有两个线程，threadOne 等待用户输入，threadTwo 在收到用户输入之前使用 interrupt() 方法中断它。我想在成功中断 threadOne 后执行一段代码。我尝试通过在 threadOne 的 run() 方法中捕获 ClosedByInterruptException 来实现这一点，但编译器给出以下错误:

异常 ClosedByInterruptException 已被捕获。

代码如下:

class InputInterruption {
public static void main(String[] args) {    

    final Thread t2 = new Thread() {
        public void run() {
                try {
                    System.out.print("make a selection: ");
                    String userInput = (new BufferedReader(new InputStreamReader(System.in))).readLine();
                    System.out.println(String.format("user input: %s", userInput));
                } catch (IOException e) {
                    System.out.println("Oops..somethign went wrong.");
                    System.exit(1);
                 } catch(ClosedByInterruptException e) {
                    System.out.println("Successfully interrupted");
                }
        }
    };
    t2.start();



    Thread t1 = new Thread() {
        public void run() {
            try {
                sleep(1000);
                System.out.println("interrupting InputStreamReader");
                t2.interrupt();
                System.exit(0);
            } catch (InterruptedException e) {
                System.out.println("Successfully interrupted");
            }
        }
    };
    t1.start();
}

}

ClosedByInterruptionException 扩展了 IOException。尝试切换 catch 语句的顺序。
