无法捕获SocketTimeoutExeption

Question

我正在尝试捕获SocketTimeoutException,以便我的套接字保持活动状态,并且可以继续读取程序。不幸的是，无论我如何尝试捕获读取超时，我都无法捕获，因此应用程序关闭。

String response;
try {
        response = input.readLine();
        System.out.println("Server Response: " + response);
        return;
} catch(AssertionError e){
    //we timed out. print to user that timeout occured,
    //try command again
    System.out.println("TIMEOUT: Please try your command again.\n"
        + "If you created a game, join an existing or create again.");
} catch (SocketTimeoutException e) {
    //we timed out. print to user that timeout occured,
    //try command again
    System.out.println("TIMEOUT: Please try your command again.\n"
        + "If you created a game, join an existing or create again.");
} catch (IOException ex) {
//do nothing
}

这不是真正的代码，您在某个地方有自己的SocketTimeoutException类，或者您导入了错误的类。我建议您在catch IOException块中放入一些有用的东西。你可能会得到一个惊喜。

为什么要捕获AssertionError并将其视为超时对我来说是个谜。
