Java Socket编程如何才能更好的进行相关代码的学习，当然我们只有不断的研究才能更好的使用。下面我们就详细的学习下。

Java Socket编程在我们编程序的时候有很广泛的应用，在应用的时候我们就会遇到不少的障碍。下面我们就看看如何才能更好的进行相关问题的学习。希望大家看完下面的代码对JavaSocket编程有所收获。

package sterning;  
import java.io.BufferedReader;  
import java.io.IOException;  
import java.io.InputStream;  
import java.io.InputStreamReader;  
import java.io.OutputStream;  
import java.io.PrintWriter;

public class MultiThreadServer {  
private int port=8821;  
private ServerSocket serverSocket;  
private ExecutorService executorService;//线程池  
private final int POOL_SIZE=10;//单个CPU线程池大小  
public MultiThreadServer() throws IOException{  
serverSocket=new ServerSocket(port);  
//Runtime的availableProcessor()方法返回当前系统的CPU数目.  
executorService=Executors.newFixedThreadPool
(Runtime.getRuntime().availableProcessors()*POOL_SIZE);  
System.out.println("服务器启动");  
}  
public void service(){  
while(true){  
Socket socket=null;  
try {  
//接收客户连接,只要客户进行了连接,就会触发accept();从而建立连接  
socket=serverSocket.accept();  
executorService.execute(new Handler(socket));  
} catch (Exception e) {  
e.printStackTrace();  
}  
}  
}  
public static void main(String[] args) throws IOException {  
new MultiThreadServer().service();  
}  
}  
class Handler implements Runnable{  
private Socket socket;  
public Handler(Socket socket){  
this.socket=socket;  
}  
private PrintWriter getWriter(Socket socket) throws 
IOException{  
OutputStream socketsocketOut=socket.getOutputStream();  
return new PrintWriter(socketOut,true);  
}  
private BufferedReader getReader(Socket socket) throws 
IOException{  
InputStream socketsocketIn=socket.getInputStream();  
return new BufferedReader(new InputStreamReader
(socketIn));  
}  
public String echo(String msg){  
return "echo:"+msg;  
}  
public void run(){  
try {  
System.out.println("New connection accepted "+
socket.getInetAddress()+":"+socket.getPort());  
BufferedReader br=getReader(socket);  
PrintWriter pw=getWriter(socket);  
String msg=null;  
while((msg=br.readLine())!=null){  
System.out.println(msg);  
pw.println(echo(msg));  
if(msg.equals("bye"))  
break;  
}  
} catch (IOException e) {  
e.printStackTrace();  
}finally{  
try {  
if(socket!=null)  
socket.close();  
} catch (IOException e) {  
e.printStackTrace();  
}  
}  
}  
} 

以上就是对Java Socket编程的相关代码介绍。
