java socket初步学习一 ( tcp)

Java socket通信程序:

第一版本:

实现功能:

服务器地址:127.0.0.1  端口:5050

客户机:端口5050

客户端发送字符;“t

服务器接收到该字符并回复:“r

 

流程:

建立java工程,默认在workspace中,udpServer为工程名,此时work/udpServer文件夹

建立类名为server,则此时服务器代码为:

 

package udpServer;

import java.io.*;
import java.net.*;

public class server {

    public static void main(String[] args) throws IOException{
        // TODO Auto-generated method stub
        ServerSocket listen = new ServerSocket(5050);
        
        Socket server  = listen.accept();

        InputStream in = server.getInputStream();
        OutputStream out = server.getOutputStream();

        char c = (char)in.read();
        System.out.println("收到:" + c);

        out.write('r');
        
        out.close();
        in.close();
        server.close();
        listen.close();
    }

}

 

建立java工程,由于eciplse不兼容同一个工作空间,此时修改临时工作空间路径为/workspace/udp

工程名为udpClient,那么对应物理路径为work/udp/udpClinet

类名为client,此时客户端代码:

 

package udpClient;

import java.io.*;
import java.net.*;

public class client {

    public static void main(String[] args)throws IOException {
        // TODO Auto-generated method stub
        
        Socket client = new Socket("127.0.0.1" , 5050);

        InputStream in = client.getInputStream();
        OutputStream out = client.getOutputStream();
        
        out.write('t');

        char c = (char)in.read();
        System.out.println("收到:" + c);

        out.close();
        in.close();
        client.close();
    }

}
