ObjectInputStream与ObjectOutputStream的使用问题-01

ObjectInputStream会阻塞程序，直到对应的ObjectOutputStream准备好

官方API解释：

Creates an ObjectInputStream that reads from the specified InputStream.

A serialization stream header is read from the stream and verified.

This constructor will block until the corresponding ObjectOutputStream has written and flushed the header.

例如：在Socket中使用时，要注意先后顺序

//客户端发起连接
Sockets = new Socket(serverHost,serverPort);
//注意输入输出流的获取顺序
ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream());
ObjectInputStream ois = new ObjectInputStream(s.getInputStream());
