Normally, a server runs on a specific computer and has a socket that is bound to a specific port number. The server just waits, listening to the socket for a client to make a connection request. On the client-side: The client knows the hostname of the machine on which the server is ...

消息的目的地使用socket地址来表示。一个socket地址是由网络地址和端口号组成的通信标识符。 进程间通信操作需要一对儿socket。进程间通信通过在一个进程中的一个socket与另一个进程中得另一个socket进行数据传输来完成。当一个消息执行发出后,这个消息在发送端的socket中处于排队状态,直到下层的网络协议将这些消息发送...
By definition, asocketis one endpoint of a two-way communication link between two programs running on different computers on a network.A socket is bound to a port numberso that the transport layer can identify the application that data is destined to be sent to. 4.1. The Server Usually, a...

Let's look at a simple example that illustrates how a program can establish a connection to a server program using the Socket class and then, how the client can send data to and receive data from the server through the socket. The example program implements a client, EchoClient, that ...

同时,学java语法时,不建议在开始阶段学设计模式,面向界面编程(比如swing和awt),也建议学socket编程,因为实际开发用不到。在学java语法时,面向对象,集合,异常处理和jdbc是关键,io和多线程可以了解概念即可。 3 数据库方面,可以不用买专门的书入门,数据库方面,需要知道如何通过java里的jdbc连接数据库和通过jdbc做数据...
通过java.net中的类,Java 程序可以使用 TCP 或 UDP 在互联网上进行通信。URL、URLConnection、Socket和ServerSocket类都使用 TCP 在网络上进行通信。DatagramPacket、DatagramSocket和MulticastSocket类用于 UDP。 教程:使用 URL 原文:docs.oracle.com/javase/tutorial/networking/urls/index.html ...
