急~~~~~F关于Java网络编程中多客户端对服务端的无法访问？
//Server.java
//////////////////////////////////////
package javanet;
import java.net.*;
import java.io.*;
public class Server {
// create a server
private ServerSocket server;
private int clientCount=0;
/** Creates a new instance of Server */
public Server() {
try {
while(true){
server=new ServerSocket(8086);
System.out.println( "正在等待客户的连接： ");
Socket connectToClient=server.accept();
clientCount++;
System.out.println( "客户 "+clientCount+ "已经连接上，服务器应答就绪： ");
HandleAClient thread=new HandleAClient(connectToClient);
thread.start();
}
}
catch(BindException e){
System.out.println( "端口被占用 ");
}
catch (IOException ex) {
ex.printStackTrace();
}
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
Server server=new Server();
}
}
///////////////////////////////////////////////////
//Client.java
package javanet;
import java.net.*;

/** Creates a new instance of Client */
public Client() {
try {
System.out.println( "请求服务器： ");
contentToServer=new Socket( "localhost ",8086);
System.out.println( "请求成功，正成发送数据： ");
DataInputStream disFormServer=new DataInputStream(contentToServer.getInputStream());
DataOutputStream dosToServer=new DataOutputStream(contentToServer.getOutputStream());
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
double r=0;
while(r> =0){
r=Double.parseDouble(br.readLine());
dosToServer.writeDouble(r);
double area=disFormServer.readDouble();
System.out.println( "From Server is "+area);
}
} catch (UnknownHostException ex) {

}
catch(ConnectException e){
System.out.println( "连接超时，找不到服务器。 ");
}
catch (IOException ex) {
ex.printStackTrace();
}
}
public static void main(String[] args){

}
}
/////////////////////////////////////////////////////////
//HandleAClient.java

Thread.sleep(100);
}
}

}
catch(InterruptedException e){
System.err.println(e);

}
运行之后，服务端总是端口被占，但能运行第一个客户，以后的就没什么反应了。
高手们给个答案。急~~~~~~
[解决办法]
server=new ServerSocket(8086); 写在while(true)里面 不报错才怪！
而且while(true)还是写在构造函数里，算你狠～
