java mutable对象和immutable对象的区别 今天读jdk源码中Map.java时看到一句话: great care must be exercised if mutable objects are used as map keys; 第一次知道mutable对象这个概念,google了一下,维基百科定义如下: “In object-oriented and functional programming, an immutable object (unchangeable[1] object...
Immutable objects, on the other hand, cannot be changed after they are created, such as strings, integers, or tuples. To better comprehend these concepts, picture mutable objects as a whiteboard and immutable ones as a printed book. Just as you can write, erase and rewrite on a whiteboard...
