The usage method of Java Enumerations is as follows:<\/p>\n

    \n
  1. a set of predefined constant values that represent a set of possible options<\/li>\n<\/ol>\n
    public<\/span> enum<\/span> Weekday<\/span> {\r\n    MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Citing enumeration values: You can refer to enumeration values by using the enumeration class name followed by the enumeration value. For example:<\/li>\n<\/ol>\n
      Weekday<\/span> day<\/span> =<\/span> Weekday.MONDAY;\r\n<\/code><\/pre>\n
        \n
      1. What is your name?<\/li>\n<\/ol>\n
        String<\/span> name<\/span> =<\/span> day.name();  \/\/ \u8fd4\u56de \"MONDAY\"<\/span>\r\n<\/code><\/pre>\n
          \n
        1. Can you please explain the process in a simpler way?<\/li>\n<\/ol>\n
          if<\/span> (day == Weekday.MONDAY) {\r\n    \/\/ \u6267\u884c\u67d0\u4e9b\u64cd\u4f5c<\/span>\r\n}\r\n<\/code><\/pre>\n
            \n
          1. One way to use enumeration is by defining methods within the enum class, and then calling these methods on the enum values. For example:<\/li>\n<\/ol>\n
            public<\/span> enum<\/span> Weekday<\/span> {\r\n    MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY;\r\n\r\n    public<\/span> boolean<\/span> isWeekend<\/span>()<\/span> {\r\n        return<\/span> this<\/span> == SATURDAY || this<\/span> == SUNDAY;\r\n    }\r\n}\r\n\r\nWeekday<\/span> day<\/span> =<\/span> Weekday.SATURDAY;\r\nboolean<\/span> isWeekend<\/span> =<\/span> day.isWeekend();  \/\/ \u8fd4\u56de true<\/span>\r\n<\/code><\/pre>\n
            Enumerations also support other features such as defining fields and constructors on enumeration values, as well as implementing interfaces.<\/p>\n","protected":false},"excerpt":{"rendered":"
