检查是否选择了 switch case

Question

我如何检查是否选择案例（例如 3 ）来继续故事？ 我用java写了这个，我会详细介绍故事，但我不知道我该怎么做。我想我可以将案例相互嵌套，但如果我可以选择选项（scanner.nextInt（）;）也可以添加它们。我认为如果声明会更好，但我不知道如何检查它。我必须补充一点，在发布之前没有找到这个问题的任何答案。感谢您的审查，祝您有美好的一天

             int choice_1 = scanner.nextInt();
        switch(choice_1)
        {
            case 1:
                System.out.println("Guard: Its a honor to meet u sir.Its a pleasure to let You through \nBut do u have coin pass?");
                if(pass==1){
                    ending();
                }
                else{"You should get coin pass first. I am sure that wont be a problem for Prince *laughs*"}
                break;
            case 2:
                System.out.println("*Guard immediately avoided attack and attack u harder that u excepted");
                playerHp = playerHp -30;
                playerArmorHp = playerArmorHp - 50;
                break;

            case 3:
                System.out.println("Guard : Goodbye Sir");
                plan();
                break;
            default:
                System.out.println("Guard is impatient of your not telling anything.Choose option before making him mad.\n"+line);
                break;
        }
        if(switch ( case:3)){
            System.out.println("Do u have coin pass?");
            int pass = scanner.nextInt();
        }

Answer 1

您可以将 if 子句更改为 if(choice_1 == 3) 以获得您想要的。
