问题描述
我在学习如何用Java Socket编程。我见过的客户端/服务器应用程序的例子有一些使用 DataOutputStream类，和一些使用的ObjectOutputStream 。
I'm learning about socket programming in Java. I've seen client/server app examples with some using DataOutputStream, and some using ObjectOutputStream.
什么是两者之间的区别是什么？
What's the difference between the two?
有没有性能上的差异？
推荐答案
的DataInput / OutputStream的执行通常更好，因为它更简单。它只能读/写primtive类型和字符串。
DataInput/OutputStream performs generally better because its much simpler. It can only read/write primtive types and Strings.
的ObjectInput / OutputStream中可以读/写任何对象类型是和原语。这是效率较低，但更容易使用，如果你想发送复杂的数据。
ObjectInput/OutputStream can read/write any object type was well as primitives. It is less efficient but much easier to use if you want to send complex data.
我会假设对象*流是最好的选择，直到你的知道的，它的性能是一个问题。
I would assume that the Object*Stream is the best choice until you know that its performance is an issue.
