本文介绍了在Java中继承静态变量的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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; }
}
