Java报错，是不是我的端口号不行？？？

这是代码，先是Server端的代码，然后是Client端的代码，然后是Client的报错信息，Server端的代码没有报错！

这是Server端

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.ServerSocket;

import java.net.Socket;

import java.util.ArrayList;

import java.util.List;



//接受客户端发来的消息，然后发送给所有在线的客户端

public class Server {



	public static List<Socket> sockets=

			new ArrayList<Socket>();

	public static List<String> names=new ArrayList<String>();

	

	public static void main(String args[]){

		try {

			names.add("小白");

			names.add("小黑");

			names.add("小红");

			names.add("小蓝");

			names.add("小青");

			System.out.println("服务器启动");

			ServerSocket server=new ServerSocket(16469);

			int content=0;

			while(true){				

				System.out.println("等待客户端链接");

				Socket s=server.accept();//等待客户端链接

				sockets.add(s);

				System.out.println("客户端已链接，目前在线人数"+sockets.size());

				new ServerThread(s,names.get(content++)).start();//服务器为每一个客户端分配线程

			}

		} catch (IOException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		}

	}

}



class ServerThread extends Thread{

	

	private Socket s;

	private String name;

	public ServerThread(Socket s,String name){

		this.s=s;

		this.name=name;

	}

	public void run(){

		 try {

			BufferedReader br=

					new BufferedReader(

							new InputStreamReader(

									 s.getInputStream()));

			while(true){

				String content=br.readLine();//阻塞状态

				for(Socket socket: Server.sockets){

					OutputStreamWriter osw=new OutputStreamWriter(socket.getOutputStream());

					 osw.write(content);

					 osw.flush();

				}

				System.out.println(name+":"+content);

			}

		} catch (IOException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		}

	}

}

这是Client端的代码！

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.Socket;

import java.net.UnknownHostException;



public class Client {



	public static void mian(String args[]){

		try {

			System.out.println("客户端启动");

			Socket s=new Socket("127.0.0.1",16469);

			new SendThread(s).start();

			new GetThread(s).start();

			

		} catch (UnknownHostException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		} catch (IOException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		}

	}

}



//发送消息的线程

class SendThread extends Thread{

	private Socket s;

	public SendThread(Socket s){

		this.s=s;

	}

	

	public void run(){

		try {

			OutputStreamWriter osw=new OutputStreamWriter(s.getOutputStream());

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

			while(true){

				String content=br.readLine();

				osw.write(content+"\n");

				osw.flush();

			}

		} catch (IOException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		}

	}

}



//接受消息的线程

class GetThread extends Thread{

	private Socket s;

	public GetThread(Socket s){

		this.s=s;

	}

	

	public void run(){

		try {

			while(true){

				BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));

				String content=br.readLine();//阻塞

				System.out.println(content);

			}

		} catch (IOException e) {

			// TODO 自动生成的 catch 块

			e.printStackTrace();

		}

	}

}

这是Client报错信息

服务器启动

java.net.BindException: Address already in use: JVM_Bind

	at java.net.DualStackPlainSocketImpl.bind0(Native Method)

	at java.net.DualStackPlainSocketImpl.socketBind(Unknown Source)

	at java.net.ServerSocket.<init>(Unknown Source)

	at java.net.ServerSocket.<init>(Unknown Source)

这是什么问题呢？？是不是我的端口号被占用了？？
