终止不再在Java服务器上使用的客户端线程

Question

所以我有下面的代码来启动服务器并允许客户端连接到它，我的问题有两个，首先，一旦客户端断开连接，我如何让服务器终止该线程？其次，该代码允许多个连接，但当我连接第二个用户时，服务器只在该socket上响应，而不再是第一个客户端socket

有什么建议吗

public Server()
{
    try
    {           
        ServerSocket server=new ServerSocket(5000); // Creating a server socket and bind it at port 5000
        System.out.println("Server binded at "+((server.getInetAddress()).getLocalHost()).getHostAddress()+":5000");
        System.out.println("The Cash Dispenser application can now connect");

        while(true)
        {               
            socket=server.accept(); // Ready to accept client request
            System.out.println("Client connected with IP " + socket.getInetAddress());

            new ClientThread(socket).start();   // Spawn a new thread for this socket
        }           
    }
    catch(Exception err)
    {
        System.err.println("* err"+err);
    }

}

public class ClientThread extends Thread 
{
    protected Socket socket;

    public ClientThread(Socket clientSocket) 
    {
        this.socket = clientSocket;
    }

    public void run() 
    {   
        try
        {
            out=new PrintStream(socket.getOutputStream());
            BufferedReader in= new BufferedReader(new InputStreamReader(socket.getInputStream()));  // Opening the input stream to read data from client connection 
        }
        catch (IOException e)
        {
            return;
        }

        while(true)
        {
            try
            {
                socket.getInputStream().read(inputArray);
            }
            catch (IOException e)
            {
                return;
            }

            if(inputArray != null)
            {
                for(incomingData = 0; incomingData < (inputArray.length - 1); incomingData++)
                {
                    if(inputArray[incomingData] == ETX)
                    {
                        processData(inputArray);
                        break;
                    }
                }
            }

            try
            {
                Thread.sleep(10);                   
            }
            catch (InterruptedException e1)
            {

            }
        }
    }
}
