本文详细阐述了如何使用Java创建服务器端与客户端进行Socket通信的过程。通过实例演示了服务器端监听特定端口并接收客户端请求，同时客户端连接服务器端并发送数据。此过程展示了Socket通信的基本原理及其实现步骤。

首先定义好服务器端，并设定需要监听的端口。

public class MyServer {

    public static void main(String args[]){
        try {
            ServerSocket server = new ServerSocket(8889);
            Socket socket = server.accept();
            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter write = new PrintWriter(socket.getOutputStream());
            System.out.println(socket.getLocalAddress().toString());
            System.out.println(socket.getPort());
            while(true){
                String str = reader.readLine();
                System.out.println(str);
                write.println("here receive...");
                write.flush();
                if("end".equals(str)){
                    break;
                }
                //write.close();
                }
            System.out.println("END...");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

其次是客户端，发出对定义好的服务器端口的请求。

public class MyClient {

    Socket socket;
    public MyClient(){
        try {
            socket = new Socket(InetAddress.getLocalHost(),8889);
            BufferedReader in=new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out=new PrintWriter(socket.getOutputStream());
            BufferedReader write = new BufferedReader(new InputStreamReader(System.in));
            while(true){
                String str= write.readLine();
                out.println(str);
                out.flush();
                if("end".equals(str)){
                    break;
                }
            }
            System.out.println(in.readLine());
            socket.close();
        } catch (UnknownHostException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println(e);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println(e);
        }
    }
    public static void main(String args[]){
        new MyClient();
    }
}
