在枚举中使用switch-case语句时，可以根据枚举常量的不同取值来执行不同的逻辑代码。以下是一个示例：
enum Day {
MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
}
Day day = Day.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，我们声明了一个枚举类型Day，并将day赋值为Day.MONDAY。然后使用switch-case语句根据day的取值来输出不同的信息。如果day的取值不在枚举常量中，则会执行default语句块。
