java - 我怎样才能让这个开关只选择 3 个选项之一？

Question

System.out.println("Please make a selection between 1 and 3");
        int choice = s.nextInt();

        switch (choice)
        {
        case 3: System.out.println("Can a brother get some fries with that?");
        case 2: System.out.println("Cheeseburger it is.... fatso");
        case 1: System.out.println("Good choice, you could use a salad");
        break;
        default: System.out.println("Not a valid selection bruh");
        }

Answer 1

switch (choice) {
    case 3: System.out.println("Can a brother get some fries with that?"); break;
    case 2: System.out.println("Cheeseburger it is.... fatso"); break;
    case 1: System.out.println("Good choice, you could use a salad"); break;
    default: System.out.println("Not a valid selection bruh"); break;
}

我实际上只是在每个case之后添加了break，因此如果遇到1,2，它将退出您的switch ,3 或没有。
