public void RemoteServer() throws Exception{
??RunJFrame runFrame = new RunJFrame();
??ServerSocket server = null;
??Socket you = null;
??DataInputStream in =null;

??
??server = new ServerSocket(6002);
??//DataOutputStream out = null;

??in = new DataInputStream(you.getInputStream());
??//out = new DataOutputStream(you.getOutputStream());
??String ss = in.readUTF();
??System.out.println(ss);
?if(ss.equals("aa")){
??runFrame.setVisible(true);
?}??
???? in.close();
??you.close();
