Java中如何使用switch语句处理枚举类型

在Java中，可以使用switch语句处理枚举类型。下面是一个示例：

public class EnumExample {          public 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("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");                 break;         }     } } 

在上面的示例中，我们定义了一个枚举类型Day表示一周的每一天。然后在main方法中使用switch语句根据day的值来判断今天是星期几并输出对应的信息。
