為一週中的日期設定列舉時，將它們設定為常量

enum Days {
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
}

現在建立物件並設定上述常量 −

Days today = Days.Wednesday;
Days holiday = Days.Sunday;

以下是示例 −

public class Demo {
   enum Days {

      Days today = Days.Wednesday;
      Days holiday = Days.Sunday;
      System.out.println("Today = " + today);
      System.out.println(holiday+ " is holiday");
   }
}
