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
我想要以下设置:
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中可能吗?如何?如果可以避免的话,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!
常量是数据库表的名称.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
你不能完全按照你的意愿去做.也许可以接受的妥协是:
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; }
}
