枚举

// 枚举的使用
public class Demo_Template {
    public static void main(String[] args) {
        System.out.println(Week.MON);
        System.out.println(Week.MON.toString());
    }
}

enum Week {
    MON("星期一"), TUE("星期二"), WED("星期三");
    
    private String name;
    
    private Week(String Name) {
        name = Name;
    }
    
    public String toString() {
        return name;
    }
}

// 枚举的遍历
public class Demo_Template {
    public static void main(String[] args) {
        Week[] arr = Week.values();
        for (Week week : arr) {
            System.out.println(week);
        }
    }
}

enum Week {
    MON("星期一"), TUE("星期二"), WED("星期三");
    
    private String name;
    
    private Week(String Name) {
        name = Name;
    }
    
    public String toString() {
        return name;
    }
}
