怎么对socket输出的信息以byte方式输出，接收以后再转为原类型

[victory31]

就是客户端以byte的形式将各种类型的数据输出，服务器端接收以后再转换回相应的类型。
这个问题苦闷许久忘高手告知，本人系菜鸟。
下面附上服务器端客户端及转换的代码，忘达人帮我改一下，谢谢！

希望各位高手不吝赐教啊，先谢谢了！

楼主知道不知道 HTTP 协议是怎么发送数据的？是以纯文本发送的。

[老無所依]

代码收下了， 向楼主学习，我也在探索中

[ngqzmjmj]

不知道楼主要做什么,如果要实现楼主的想法客户短发什么类型的信息,服务器断就接受什么类型的信息,那这样的信息就应该是实现知道的 比如客户断发送 "你好"5一个字符型的一个byte型的
那么服务器断只要按发送的顺序读就可以了,那么完全可以用DataInputStream,DataOutputStream 来实现

[wxfJordan]

你在做有关Jabber的项目吗? 我也是. 我也在深索中, 如果你先解决请互相告知.

[takecare]

encode/decode成对即可
