问题描述

深层副本和浅层副本之间有什么区别？

What is the difference between a deep copy and a shallow copy?

推荐答案

浅层副本尽可能少。集合的浅副本是集合结构的副本，而不是元素的副本。有了浅的副本，两个集合现在共享单个元素。

Shallow copies duplicate as little as possible. A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements.

深度复制一切。集合的深层副本是两个集合，其中原始集合中的所有元素都重复。

Deep copies duplicate everything. A deep copy of a collection is two collections with all of the elements in the original collection duplicated.
