Java 不进行序列化的深度克隆

我是一名非常新的java学习者，我想在没有序列化的情况下执行深度克隆，我在互联网上读了一些文章，但仍然对没有序列化的深度克隆表示怀疑。所以我想知道，在进行深度克隆时，我还需要遵循其他规则吗，下面是我的程序

Department.java Employee.java TestCloning.java 输出 除了实现无序列化的深度克隆，还有其他选择吗？如果有，请提供链接。

试试这个

我没看到你做任何连载？！没有任何其他方法……简单的方法似乎更像是一个没有实际用途的哲学问题，因为深度克隆总是会带来缺点和陷阱。我强烈建议首先检查一下。如上所述，克隆会带来很多问题，如果你没有经验，你最终会把自己的头发拔出来
