java.lang.Object提供了默认的clone方法实现,它声明为protected和native。因此它的实现是取决于本地代码,因为它约定返回对象是通过调用super.clone()方法,任何克隆的过程最终都将到达java.lang.Object 的clone()方法,它首先检查这个相关的类是否实现了Cloneable接口,这个接口是一个标记接口,如果这个实例没有实现cloneable接...

早期Java支持接口形式的“声明多继承” 早期Java不支持任何“实现多继承”(简称“多继承”)。从Java 8开始可以通过接口的default method实现。 把上述几条结合起来,就得到了Cloneable接口这个糟糕的设计。 怎么说呢? 首先,我们要能标记出哪些类是可以clone的。在Java里,类型层面的元数据可以用几种方法来表示: ...

The Java Object clone() method creates a shallow copy of the object. In this tutorial, we will learn about the Object clone() method with the help of examples.
