java socket 实现多个客户端向服务器上传文件

服务器端：

package cn.com.test09;

import java.io.DataInputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class t10 {

    public static void main(String[] args) {
          new ServerO("F:\\",8080);
    }
}

class ServerO {
    private String path;
    private int port;
    private ServerSocket ss;

    public ServerO(String s, int p) {
        this.path = s;
        this.port = p;
        try {
            ss = new ServerSocket(port);

                Socket soc = ss.accept();
                new Thread(new OOOO(soc,path)).start();
            }

        } catch (IOException e) {
