Java Socket多线程编程示例，socket多线程编程,客户端代码如下：

客户端代码如下：

    import java.io.*;      import java.net.*;      import java.util.Scanner;      public class SimpleChatClient {          BufferedReader reader;          PrintWriter writer;          Socket sock;          public void go(){              System.out.println("客户端启动！");              setUpNetworking();              //发送数据到服务器              Scanner scanner=new Scanner(System.in);              String sendString=scanner.nextLine();              while(sendString!=null&&!sendString.equals("byebye")){                  writer.println(sendString);                  writer.flush();                  sendString=scanner.nextLine();              }              scanner.close();              System.out.println("客户端退出！");          }          public void setUpNetworking(){              try {                  sock=new Socket("127.0.0.1",5000);                  InputStreamReader streamReader=new InputStreamReader(sock.getInputStream());                  reader=new BufferedReader(streamReader);                  writer=new PrintWriter(sock.getOutputStream());                  System.out.println("networking established");              } catch (IOException e) {                  // TODO Auto-generated catch block                  e.printStackTrace();              }          }          public static void main(String[] args) {              // TODO Auto-generated method stub              SimpleChatClient client=new SimpleChatClient();              client.go();          }      }  

服务器端代码如下：```java import java.io.;
import java.net.;
public class SimpleChatServer {
//内部类
public class ClientHandler implements Runnable{
BufferedReader reader;
Socket sock;

        public ClientHandler(Socket clientSocket){              sock=clientSocket;              InputStreamReader isReader;              try {                     isReader = new InputStreamReader(sock.getInputStream());                  reader=new BufferedReader(isReader);              } catch (IOException e) {                  // TODO Auto-generated catch block                  e.printStackTrace();              }        }             @Override          public void run() {              // TODO Auto-generated method stub              String messageString;              try {                  while((messageString=reader.readLine())!=null){                      System.out.println("read "+messageString);                  }              } catch (IOException e) {                  // TODO Auto-generated catch block                                System.out.println("有一个连接断开");              }          }    }      public void go(){          System.out.println("服务器启动成功！");          ServerSocket serverSock;          try {              serverSock = new ServerSocket(5000);              while(true){                  Socket clientSocket=serverSock.accept();                  Thread thread=new Thread(new ClientHandler(clientSocket));                  thread.start();                  System.out.println("got a connection!");              }          } catch (IOException e) {              // TODO Auto-generated catch block              e.printStackTrace();          }    }    public static void main(String[] args) {          // TODO Auto-generated method stub          new SimpleChatServer().go();      }}
