在Java中发布全局常量的更好的方法是什么？ [英] What is the better way of publishing global constants in Java?

问题描述

发布全局常量的哪种方式之一更好？谢谢!!!

Which one of these ways of publishing global constants is better? THANKS!!!

方法1：具有公共静态终场的最终课

public final class CNST{
    private CNST(){}
    public static final String C1;
    public static final String C2;
    static{
       C1="STRING1";
       C2="STRING2";
    }
}
//so I could call C1, C2 like:
//...some code...
//System.out.println(CNST.C1);
//System.out.println(CNST.C2);

方法2：带枚举的单例 p>

Method 2: singleton with enum

public enum CNST{
    INST;
    public final String C1;
    public final String C2;
    CNST{
       C1="STRING1";
       C2="STRING2";
    }
}
//so I could call C1, C2 like:
//...some code...
//System.out.println(CNST.INST.C1);
//System.out.println(CNST.INST.C2);

推荐答案

遵循更常规惯例的东西就是这样：

Something that follows more usual conventions would be like this:

public class MyAppConstants {
    public static final String C1 = "STRING1";
    public static final String C2 = "STRING2";
}

然后你可以这样引用它：

Then you can refer to it later like this:

System.out.println(MyAppConstants.C1);

但是如果我不得不选择两者之间给我，我想我会选择第一个，因为枚举是有误导性的，并不能在功能上有所帮助，也不会使代码更清晰。

But if I had to pick between the two you give I guess I would choose the first, because the enum is misleading and doesn't help functionally and doesn't make the code clearer.
