网络编程的问题

Question

BufferedReader br=new BufferedReader(new InputStreamReader(in));
                    
                    while((temp=br.readLine())!=null)
                    {
                    
                     System.out.println("receive client message :"+ temp); 
                     if(!temp.equals(""))
                     {
                     String divide[]=temp.split("/");
                     Sql log =new Sql();
                    
                     if(log.Logo(divide[0], divide[1])==1)
                     {
                     OutputStream out=socket.getOutputStream();
                                     PrintWriter pw=new PrintWriter(out,true);
                                     pw.println("1");
                     log.update_Ip(string_ip,divide[0]);
                     }
                  }
                                         }请问我这样写为什么不能像客户端写入“1”呢？？

}还是把全部代码贴出来吧！！
客户端没问题，关键是服务器的问题。OutputStream out = socket.getOutputStream();
                            PrintWriter pw=new PrintWriter(out,true);
                                     pw.println("1");
这段代码已经是执行了，但是客户端收不到

Answer 2

为什么把OutputStream out = socket.getOutputStream();
                                PrintWriter pw=new PrintWriter(out,true);
                                            pw.println("1");移动到WHILE的前面就能收到呢??
