Javasocket应用实例

引导语：运用Java，我们可以编出很多有趣的'小程序，以下是百分网小编分享给大家的Javasocket应用实例，希望大家喜欢!

用于本机上的客户端与服务器对话的小程序：

客户端：

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.Socket;

public class Client extends Thread

{

public void Write() throws Exception

{

Socket s=new Socket("127.0.0.1",12345);

BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

String message="客户端说:";

while(!(message.equals("")))

{

message=br.readLine();

System.out.println("客户端说:"+message);

bw.write(message+"\n");

bw.flush();

}

bw.close();

s.close();

}

public void run()

{

Socket m=null;

BufferedReader dr=null;

try

{

m=new Socket("127.0.0.1",12345);

dr=new BufferedReader(new InputStreamReader(m.getInputStream()));

String msg="服务器说:";

while(!(msg.equals("")))

{

msg=dr.readLine();

System.out.println("服务器说:"+msg);

}

}

catch(Exception e){e.printStackTrace();}

finally

{

try

{

dr.close();

m.close();

}

catch(Exception e){e.printStackTrace();}

}

}

public static void main(String args[])throws Exception

{

Client c=new Client();

c.start();

c.Write();

}

}

服务器：

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.ServerSocket;

import java.net.Socket;

public class Server extends Thread

{

private ServerSocket ss=null;

public Server ()throws Exception

{

ss=new ServerSocket(12345);

}

public void Write()throws Exception

{

Socket s=ss.accept();

BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

String message="服务器说:";

while(!(message.equals("")))

{

message=br.readLine();

System.out.println("服务器说:"+message);

bw.write(message+"\n");

bw.flush();

}

//bw.close();

s.close();

}

public void run()

{

Socket m=null;

BufferedReader dr=null;

try

{

m=ss.accept();

dr=new BufferedReader(new InputStreamReader(m.getInputStream()));

String msg="客户端说:";

while(!(msg.equals("")))

{

msg=dr.readLine();

System.out.println("客户端:"+msg);

}

}

catch(Exception e){e.printStackTrace();}

finally

{

try

{

dr.close();

m.close();

}

catch(Exception e){e.printStackTrace();}

}

}

public static void main(String args[])throws Exception

{

Server s=new Server();

s.start();

s.Write();

}

}
