在这篇文章中我们将介绍套接字(Socket)慨念,同时以实例说明如何使用Network API操纵套接字,在完成本文后,你就可以编写网络低端通讯软件。 什么是套接字(Socket)? Network API是典型的用于基于TCP/IP网络Java程序与其他程序通讯,Network API依靠Socket进行通讯。Socket可以看成在两个程序进行通讯连接中的一个端点,一...

In Java programming, each object has a lock; a thread can acquire the lock for an object by using the synchronized keyword. Methods, or synchronized blocks of code, can only be executed by one thread at a time for a given instantiation of a class, because that code requires obtaining the...
Using Java and the socket interface in teaching client/server programming The server program in the prototype is a JAVA application that runs on a web server all the time. The client and the server programs use the socket interface [ Comer&Stevens 96] as the communication protocol, and are ...
In java void* void* Java now provides a type-safe way to set options. Each socket class has a get/set method for each option it supports, taking and returning the appropriate type. The options supported, for which socket classes and their meaning in brief: ...
Python 里面用(ip, port)的元组来表示 socket 的地址属性,用AF_*来表示协议类型。 数据通信有两组动词可供选择:send/recv或read/write。read/write方式也是Java采用的方式,这里不会对这种方式进行过多的解释,但是需要注意的是: read/write操作的具有 buffer 的“文件”,所以在进行读写后需要调用flush方法去真正发...
A socket is a communications connection point (endpoint) that you can name and address in a network. Socket programming shows how to use socket APIs to establish communication links between remote and local processes.
