1 服务器端程序，接受连接并处理客户端的请求

ServerApp.java
    package test;

2 客户端程序，发送每次猜的数字

   package test;
    import java.io.*;
    import java.net.*;
    public class ClientApp ...{
      private Socket socket;
      private BufferedReader netIn;
      private PrintWriter netOut;
      private BufferedReader keyboardIn;

      static Boolean finished = false;
      public ClientApp() throws IOException ...{
        System.out.println("请输入服务器地址，连接本地服务器请输入localhost");
        keyboardIn = new BufferedReader(new InputStreamReader(System.in));
        try ...{
          if (keyboardIn.readLine().equalsIgnoreCase("localhost")) ...{
            socket = new Socket(InetAddress.getLocalHost(), ServerApp.PORT);
          } else ...{
            socket = new Socket(InetAddress.getByName(keyboardIn.readLine()), ServerApp.PORT);
          }
          netIn = new BufferedReader(new InputStreamReader(socket.getInputStream()));

          netOut = new PrintWriter(socket.getOutputStream());
        } catch (UnknownHostException e) ...{
          System.err.println("连接不到服务器");
          System.exit(-1);
        }
        System.out.println("连接成功");
        while (!finished) ...{
          System.out.println("请输入0－100之间的数字");
          netOut.println(keyboardIn.readLine());
          netOut.flush();
          String str = netIn.readLine();
          if (str == null) ...{
            finished = true;

            break;
