你真的没有理由可以真正做到这一点.

There's really no reason why you can actually do this.

我唯一的猜测是它允许您覆盖静态方法，但您不能.

My only guess was that it would allow you to override static methods, but you can't.

如果您尝试以下场景:

Banana 有一个名为 'test' 的静态方法(打印出 'banana')Apple 扩展了 Banana 并覆盖"了名为test"的静态方法(这会打印apple")

Banana has a static method called 'test' (this prints 'banana') Apple extends Banana and "overrides" the static method called 'test' (this prints 'apple')

然后你做这样的事情:

public static void main(String[] args) {
    Apple apple = new Apple();
    Banana banana = new Banana();
    Banana base = new Apple();

    apple.test();
    banana.test();
    base.test();
}

结果输出为:

apple
banana
banana

如此有效，却毫无用处.

So effectively, it's pretty useless.
