The Constructor: Set up the interface： // Constructor public Client( String host, int port ) { // Set up the screen setLayout( new BorderLayout() )。re going to be talking to the client, we should talk a little bit about our munication protocol. Every client/server system has a munications protocol, which is nothing more than the format you use to send the data back and forth. The protocol can be so simple it hardly deserves the title of protocol, or it can be a sophisticated standard that has been ratified by consortia all over the world. Either way, it39。s waiting for user 0 to say something, then it39。 // Create a DataOutputStream for writing data to the // other side DataOutputStream dout = new DataOutputStream( () )。s take a look at the code that does all this. The code below takes care of the things we39。s what it looks like, in the abstract: // start listening on the port ServerSocket ss = new ServerSocket( port )。re all ready to listen, we39。 The most important thing to know about a Socket object is that it contains (among other things) two Streams. One is for reading data ing in, and the other is for writing data is to say, a Socket has an InputStream and an OutputStream.(If these Stream classes are unfamiliar to you, then suffice it to say that they are objects used for reading and writing data, often as a stream of bytes. If you don39。ll be using nothing more than the basic packages built into every Java implementation. This allows us to explore server programming at the very lowest level possible in the Java language. There are certainly many systems available that can take care of many of these working details for you. In many cases, the best realworld solution is to use an existing framework, because it often provides useful features such as faulttolerance, loadbalancing. What does the server do? Before we describe the Listener class, we39。 畢業(yè)設(shè)計(jì)（論文）外文參考文獻(xiàn)翻譯 計(jì)算機(jī)科學(xué)與信息工程系 系（院） 2020 屆 題 目 企 業(yè) 即 時(shí) 通 Instant Messaging for Enterprises 課題類型 技術(shù)開發(fā) 課題來源 自 選 學(xué)生姓名 許帥 專業(yè)班 級(jí) 04 計(jì)算機(jī)科學(xué)與技術(shù) 指導(dǎo)老師 王占中 職 稱 工程師 完成日期： 2020 年 4 月 6 日 目 錄 INSTANT MESSAGING FOR ENTERPRISE .................................. 1 1.
