public class MyServer {public static void main(String[] args) throws IOException {ServerSocket serverSocket new ServerSocket(9000);while (true){Socket scoket serverSocket.accept();new WorkThread(scoket).start();}}
}
class WorkThread extends Thread{private Socket scoket;public WorkThread(Socket scoket){this.scoket scoket;}Overridepublic void run() {try {InputStream is scoket.getInputStream();OutputStream os scoket.getOutputStream();BufferedReader br new BufferedReader(new InputStreamReader(is));PrintWriter out new PrintWriter(os);String str br.readLine();out.println(收到str);out.flush();out.close();br.close();scoket.close();} catch (IOException e) {System.out.println(e.getMessage());}}
}
客户端编程实现
public class MyClient {public static void main(String[] args) throws IOException {BufferedReader br new BufferedReader(new InputStreamReader(System.in));System.out.println(你想给服务器说);String str1 br.readLine();Socket socket new Socket(localhost,9001);System.out.println(socket.getInetAddress());System.out.println(socket.getPort());InputStream is socket.getInputStream();OutputStream os socket.getOutputStream();BufferedReader br2 new BufferedReader(new InputStreamReader(is));PrintWriter out new PrintWriter(os);out.println(str1);out.flush();String str2 br2.readLine();System.out.println(str2);br2.close();out.close();br.close();}
}
