公共枚举中的主要方法 [英] main method in a public enum

问题描述

嗨 此代码有什么问题?
我无法编译.

public enum Days{
    monady(1),
    tuesday(2),
    wedenesday(3),
    thursday(4),
    friday(5),
    saturday(6),
    sunday(7);
    private final int dayValue;
    Days(int count)
    {
        this.dayValue=count;
    }
    public int getDayValue()
    {
        return dayValue;
    }
    public static void main(String[] args)
    {
        for(Days day:Days.values())
        {
             System.out.println("The day is "+day+" ,The value of day is:"+day.getDayValue());
        }
    }
}

解决方案

我刚刚编译并运行了此代码，没有任何问题.尝试时究竟发生了什么?

我认为除了enum中的常量之外，您实际上不能定义任何其他东西.我可能是错的，但是这些教程似乎与我一致:枚举类型 [ ^ ]
因此，尝试将整个程序包含在enum 中总是会以眼泪结束...

hi what is wrong with this code?
i can not compile it.

public enum Days{
    monady(1),
    tuesday(2),
    wedenesday(3),
    thursday(4),
    friday(5),
    saturday(6),
    sunday(7);
    private final int dayValue;
    Days(int count)
    {
        this.dayValue=count;
    }
    public int getDayValue()
    {
        return dayValue;
    }
    public static void main(String[] args)
    {
        for(Days day:Days.values())
        {
             System.out.println("The day is "+day+" ,The value of day is:"+day.getDayValue());
        }
    }
}

解决方案

I have just compiled and run this code without problems. What exactly happens when you try?

I don''t think you can actually define anything other than constants in an enum. I could be wrong, but the tutorials seem to agree with me: Enum Types[^]
So trying to include your whole program in an enum is always going to end in tears...
