Sometimes you need to clone objects, and sometimes you can't use their clone method, and sometimes serialization provides an alternative. Here's an explanation of when you might need this exotic and expensive technique, and how you can use it. When d…

关于Java的序列化的文章在网上已经够多了,在这里写关于Java序列化的文章是对自己关于这方面的的一种总结,结合以前的开发经验与网上的资料,写了这篇文章,对自己是有着巩固记忆的作用,也希望能够对大家有一定帮助. 一.什么是序列化(Serialization)? 序列化是Java提供的一种机制,将对象转化成字节序列,在字节序列中保存了对象的数据.对象的类型的信息与存储在对象中的数据的类型.序列化实际上就是将保存对象的"状态",可以方便以后的程序使用或者通过网络传输到另一台主机使用.一般来…

Assets和Objects Asset是存储在硬盘上的文件,保存在Unity项目的Assets文件夹内.比如:纹理贴图.材质和FBX都是Assets.一些Assets以Unity原生格式保存数据,例如材质.另一些Assets需要通过处理转换到原生格式,例如FBX. Object是一系列序列化数据,这些数据描述了具体的资源实例,这可以是Unity使用的任意类型的资源,例如mesh,sprite,audio clip或animation clip.所有的Objects都是UnityEngine.O…

System.out.println(Objects.hashCode(obj)); System.out.println(Objects.toString(obj)); System.out.println(Objects.requireNonNull(obj, "obj参数不能为空")); output: null Exception in thread "main" java.lang.NullPointerException: obj参数不能为空 at ja…

基本使用方法               Serialization是指把类或者基本的数据类型持久化(persistence)到数据流(Stream)中,包括文件.字节流.网络数据流.          JAVA中实现serialization主要靠两个类:ObjectOuputStream和ObjectInputStream.他们是JAVA IO系统里的OutputStream和InputStream的子类.既然他们是JAVA IO中的流,那么就可以像操作一般的流一样来操作他们.下面是他们使用…
