简单枚举示例

1、简单的枚举

public enum Day {
    //名（值）
    MONDAY,
    TUESDAY,
    WEDNESDAY,
    THURSDAY,
    FRIDAY,
    SATURDAY,
    SUNDAY;//记住要用分号结束

}

public class Main {
    public static void main(String[] args) {
        System.out.println(Day.TUESDAY);
    }
}

打印结果：
TUESDAY

2、带有描述的枚举

public enum Day {
    //名（值）
    MONDAY("周一"),
    TUESDAY("周二"),
    WEDNESDAY("周三"),
    THURSDAY("周四"),
    FRIDAY("周五"),
    SATURDAY("周六"),
    SUNDAY("周日");//记住要用分号结束
    private String value;
    private Day(String value){
        this.value=value;
    }

    public String getValue() {
        return value;
    }
}

public class Main {
    public static void main(String[] args) {
        Day day =Day.TUESDAY;
        System.out.println("英文名称："+day.name());
        System.out.println("汉语名称："+day.getValue());
    }
}
打印结果：
英文名称：TUESDAY
汉语名称：周二
