java - java中允许多个用户输入

Question

我正在制作一个可以与你进行对话的人工智能。 当你运行程序时，计算机会说“嗨”，用户可以输入多个问候语(例如“你”、“你好”等)

我的问题是当计算机询问用户“你好吗？”时和用户回答。我编写了一个开关，如果你说“好”之类的话，计算机就会回复“很高兴听到它”。 ，但事实并非如此。我做错了什么？

这是我的代码:

    System.out.println("hi");
    Thread.sleep(3000);

    System.out.println("The computer would like to remind you to reply with only a greeting");

    Scanner rexy = new Scanner(System.in);
    String domino = rexy.nextLine();


    switch (domino){
        case "hello":
            System.out.println("How are you?");
            break;

        case "hi":
            System.out.println("How are you?");
            break;

        case "howdy":
            System.out.println("How are you?");
            break;

        case "heyo":
            System.out.println("How are you?");
            break;

        case "hello?":
            System.out.println("How are you?");
            break;

        case "hey":
            System.out.println("How are you?");
            break;

        case "sup":
            System.out.println("How are you?");
            break;

        case "good":
            System.out.println("Glad to hear it");
            break;

        case "great":
            System.out.println("Glad to hear it");
            break;

        case "awesome":
            System.out.println("Glad to hear it");
            break;

        case "splendid":
            System.out.println("Glad to hear it");
            break;

        case "fantastic":
            System.out.println("Glad to hear it");
            break;


        case "fine":
            System.out.println("Glad to hear it");
            break;

        case "what's crackalakin?":
            System.out.println("How are you?");
            break;

        case "what's up turd face?":
            System.out.println("That's rude! How are you?");
            break;

    }
}

}

谢谢。

您可以尝试在开关中添加一个default语句，以便在无法识别答案时有后备；像这样:

switch (domino) {
  //...
default:
    System.out.println("Sorry, I don't understand that.");
    break;
}

此外，您可以尝试打印 domino 字符串，以查看实际读取的内容。

System.out.println(domino);

另外，还有一个提示:您可以在 switch 中连接多个相等的 case 语句，如下所示:

switch (domino) {
    case "hello":
    case "hi":
    case "howdy":
    case "heyo":
    case "hello?":
    case "hey":
    case "sup":
        System.out.println("How are you?");
        break;
    case "good":
    case "great":
    case "awesome":
    case "splendid":
    case "fantastic":
    case "fine":
        System.out.println("Glad to hear it");
        break;
}
