java - 扫描仪不会接受输入，因此无法处理它

Question

该类运行，但当我在扫描仪中输入内容时，什么也没有发生。它应该注册输入并运行另一个类，然后我在其中获取响应并尝试打印它。

public class Eliza {
    public static void main(String[] args) {
        String line = "";
        String response = "";
        ElizaResponder responder = new ElizaResponder();

        System.out.println("Welcome to Christian Rebelo's Eliza");
        System.out.println("---------------------------");
        System.out.println("ELIZA> " + responder.getGreeting());

        Scanner s = new Scanner(System.in);

        while (responder.isNotFinished()) {
            line = s.nextLine();
        }

        response = responder.getResponse(line);
        System.out.println(response);

        System.out.println("ELIZA> " + responder.getFarewell());
    }
}

Answer 1

从评论来看，它看起来像这样:

while (responder.isNotFinished()) {
    line = s.nextLine();
}
    response = responder.getResponse(line);
    System.out.println(response);

应该是这样的:

while (responder.isNotFinished()) {
    line = s.nextLine();

    response = responder.getResponse(line);
    System.out.println(response);
}
