java socket通讯交互

　　Recently,I was studing the linux OS (redhat 9),involving the java net.The server-side is in the linux OS ,and the Client-side is in windows OS .The code is here:

　　Server-side

import java.io.*;
import java.net.*;
public class HelloServerTest {

    public static void main(String[] args) {
        try {
            //创建ServerSocket
        ServerSocket ss=new ServerSocket(8888);
        System.out.println("I am listening");
        
        Socket s=ss.accept();
        
        //可以从客户端读取消息
        InputStreamReader isr=new InputStreamReader(s.getInputStream());
        BufferedReader br=new BufferedReader(isr);
        String kk=br.readLine();
        System.out.println("客户端传过来的消息是:"+kk);
        System.out.println(" the message from client is :"+kk);
        
        OutputStreamWriter osw=new OutputStreamWriter(s.getOutputStream());
        PrintWriter pw=new PrintWriter(osw,true);
        pw.println("message from the server");
        } catch (Exception e) {
            // TODO: handle exception
        }
    }

}

　　Client-side

import java.io.*;
import java.net.*;
public class ClientTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
try {
    //连接ip 和port
    Socket s=new Socket("192.168.148.10",8888);
    OutputStreamWriter osw=new OutputStreamWriter(s.getOutputStream());
    BufferedWriter bw=new BufferedWriter(osw);
    PrintWriter pw=new PrintWriter(bw,true);
    pw.println("Hello,zouteng,java net");
    
    InputStreamReader isr=new InputStreamReader(s.getInputStream());
    BufferedReader breader=new BufferedReader(isr);
    String kk=breader.readLine();
    System.out.println("服务器反馈的信息： "+kk);
} catch (UnknownHostException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
    }

}
