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"。
