Socket编程:聊天室不同版本V2

聊天室案例V2.
改善聊天室案例V1,实现客户端重复发送数据到服务器端的功能,即用户可以在控制台不断
输入内容,并将内容逐一发送给服务端
1.对于客户而言,为了能够重复发送,需要构建循环,并在循环中,不断读入控制台录入的数据
并发送
2.对于服务器端,也需要构建循环,并在循环中不断读取客户端发来的数据并打印显示.

TCP通信
Server端多线程的应用
.若想使一个服务端可以支持多客户端连接,我们需要解决一下问题
-1.循环调用accept方法侦听客户端的连接
-2.使用线程来处理单一客户端的数据交互

因为需要处理多客户端,所以服务端要周期性循环调用accept方法,但该方法会产生阻塞,所
以要与某个客户端的交互就需要使用线程来并发处理
public class Client2 {
   private Socket socket;
   public Client2() {
       try {
           socket = new Socket("localhost", 8060);
       }catch (IOException e) {
           e.printStackTrace();
       }
   }

   public void start() {
       try {
           OutputStream os = socket.getOutputStream();
           OutputStreamWriter osw = new OutputStreamWriter(os, "utf-8");
           PrintWriter pw = new PrintWriter(osw,true);
           Scanner scanner = new Scanner(System.in);
           while(true) {
               pw.println(scanner.nextLine());
           }

       } catch (IOException e) {
           e.printStackTrace();
