Java里的enum类型可以用这swich里吗

可以的，在Java中，enum类型可以用在switch语句中。以下是一个示例：

public class Main {
   
    enum Day {
   
        MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
    }

    public static void main(String[] args) {
   
        Day day = Day.MONDAY;

        switch (day) {
   
            case MONDAY:
                System.out.println("星期一");
                break;
            case TUESDAY:
                System.out.println("星期二");
                break;
            case WEDNESDAY:
                System.out.println("星期三");
                break;
            case THURSDAY:
                System.out.println("星期四");
                break;
            case FRIDAY:
                System.out.println("星期五");
                break;
            case SATURDAY:
                System.out.println("星期六");
                break;
            case SUNDAY:
                System.out.println("星期日");
                break;
            default:
                System.out.println("无效的枚举值");
                break;
        }
    }
}
