在Java中继承静态变量 [英] Inherit a Static Variable in Java

问题描述

我希望进行以下设置：

abstract class Parent {
    public static String ACONSTANT; // I'd use abstract here if it was allowed

    // Other stuff follows
}

class Child extends Parent {
    public static String ACONSTANT = "some value";

    // etc
}

这在java中是否可行？怎么样？如果我可以避免它，我宁愿不使用实例变量/方法。

Is this possible in java? How? I'd rather not use instance variables/methods if I can avoid it.

谢谢！

编辑：

constant是数据库表的名称。每个子对象都是一个迷你ORM。

The constant is the name of a database table. Each child object is a mini ORM.

推荐答案

你无法完全按照自己的意愿去做。也许可接受的折衷方案是：

you can't do it exactly as you want. Perhaps an acceptable compromise would be:

abstract class Parent {
    public abstract String getACONSTANT();
}

class Child extends Parent {
    public static final String ACONSTANT = "some value";
    public String getACONSTANT() { return ACONSTANT; }
}
