Java枚举值能做为switch参数吗

是的，Java枚举值可以作为switch语句的参数。枚举类型是一种特殊的类，它表示一组固定的常量，可以将枚举值作为switch语句的参数，根据不同的枚举值执行不同的逻辑。以下是一个示例：

public class EnumExample {
    
    public enum Weekday {
        MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
    }
    
    public static void main(String[] args) {
        Weekday day = Weekday.MONDAY;
        
        switch (day) {
            case MONDAY:
                System.out.println("Today is Monday");
                break;
            case TUESDAY:
                System.out.println("Today is Tuesday");
                break;
            case WEDNESDAY:
                System.out.println("Today is Wednesday");
                break;
            case THURSDAY:
                System.out.println("Today is Thursday");
                break;
            case FRIDAY:
                System.out.println("Today is Friday");
                break;
            case SATURDAY:
                System.out.println("Today is Saturday");
                break;
            case SUNDAY:
                System.out.println("Today is Sunday");
                break;
            default:
                System.out.println("Invalid day");
        }
    }
}

在上面的示例中，我们定义了一个Weekday枚举类型，然后使用switch语句根据不同的枚举值打印不同的消息。当day为Weekday.MONDAY时，输出为"Today is Monday"。
