JavaIO之ObjectInputStream 和 ObjectOutputStream

序列化是一种轻量级的持久化,对象都是存活在内存中的,当JVM运行结束,对象便不存在了如果想要对象还能够存在,或者说当你在网络中想要进行对象数据的传输的话,就需要进行序列化说白了就是内存中的数据你要把他变成字节 ObjectInputStream...约定了从二进制读取基本类型对象数组 String的方法DataOutput以及 ObjectOutput也都是接口,约定了将基本类型数据对象数组 String 转换为字节写入二进制流的方法 ObjectInputStream...和 ObjectOutputStream 相当于继承了两个体系一个体系是IO的读写方法约定另一个是从二进制读取为数据或者数据编写二进制两个体系结构的实现,构成了现在的ObjectInputStream...ObjectInputStream中的方法大多依赖于bin变量....的它内部也有一个跟BlockDataInputStream 对应的BlockDataOutputStream 不再详细介绍总结 ObjectInputStream 和 ObjectOutputStream

Java IO之对象的序列化、ObjectInputStream和ObjectOutputStream类

参考链接： Java ObjectInputStream类什么是IO流？ byte序列的读写，Java中的IO流是实现输入/输出的基础. ...我们可以使用java.io.ObjectInputStream和java.io.ObjectOutputStream类来完成这个任务。 1、什么是对象的序列化(Serialize)？...2、ObjectInputStream类和ObjectOutputStream类如果我们想要序列化一个对象，如我们自定义的User类的对象，那么这个对象必须实现Serializable接口。...下面我们使用ObjectInputStream类和ObjectOutputStream类向文件中写入3个User对象，追加1个User对象，最后再从文件中读回对象。 ...ois = new ObjectInputStream(fis); // 读取对象并放入List容器中 while(fis.available() > 0)
