Java中深拷贝(Deep Copy)和浅拷贝(Shallow Copy)学习笔记 由于在线程安全中涉及到对象的深度拷贝(Deep Copy),很早以前听说多,不多是TypeScript中听一个同事介绍,但是自己对java这块的知识还不了解,于是就打算借此机会学一下深浅拷贝,并加深一下相关技术的印象。于是查阅了一些资料,现将知识点整理如下归为以下几类进...
下面就让小编来带大家学习“java的deep vs shallow copies怎么理解”吧! 1.背景 讨论deep copy and shallow copy时,需要明白一点,肯定不是基本数据类型也不是 String,因为它们都是不可变的,都是值传递。换句话说,当讨论deep copy or shallow copy时,都针对的引用类型,在讨论的是引用如何传递 2.根本区别 看引用...

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms. In the Java context, we first need to make a distinction between "copying a value" and "copying an object". int a = 1; int b = a; // copying a value int[] s = new int[]{42}; int[]...

Java中的Clone也有浅克隆和深克隆之分,分别对应C++中的浅拷贝和深拷贝。 Shallow Copy = Bitwise Copy,Deep Copy = Memberwise Copy. Long story short, a shallow copy only copies the binary, in memory, print of a class. A deep copy “dives into” the members, and copy their logical data. Usual...
