使用java进行socket编程示例

这两天突然玩java,发现有点意思.以前不太喜欢java,主要是在许多时候做客户端并不方便,后来在许多应用方面,发现java还是很强悍的.大有相见恨晚之意.记得以前有位大师说是每年至少了解一门语言,这样方便你了解其它语言的特性,并与现在的语种进行比较.

java是一种网络语言,做网络编程应该很有意思吧.

下面是一个很简单的java的socket示例.

server端在5678端口开了服务,并进入读取客户端循环中.

 

package mysktserver;
import java.io.*;
import java.net.*;
public class Main {
    public static void main(String[] args) throws IOException
    {
        ServerSocket server = new ServerSocket(5678);
        Socket client = server.accept();
        BufferedReader in = new BufferedReader( new InputStreamReader(client.getInputStream()));
        PrintWriter out = new PrintWriter(client.getOutputStream());
        while(true)
        {
                String str = in.readLine();
                System.out.println(str);
                out.println("has receive ...");
                out.flush();
                if (str.equals("end"))
                {
                        break;
                }
                client.close();
        }
    }
}


客户端连接到本地的5678端口.

package mysktclient;
import java.net.*;
import java.io.*;
public class Main {
     static Socket server;
    public static void main(String[] args) throws Exception
    {
        server = new Socket(InetAddress.getLocalHost(),5678);
        BufferedReader in = new BufferedReader(new InputStreamReader(server.getInputStream()));
        PrintWriter out = new PrintWriter(server.getOutputStream());
        BufferedReader wt = new BufferedReader(new InputStreamReader(System.in));
        while(true)
        {
                String str = wt.readLine();
                out.println(str);
                out.flush();
                if(str.equals("end"))
                {
                        break;
                }
                System.out.println(in.readLine());
        }
        server.close();
    }
}


这个例子只是简单的做出java做socket编程的便利性.以后的日子将会更加深入.
