跪求大神解答QAQ……Java GUI JFrame窗体可以显示但是里面的组件不能显示

而且点击最大化，除了部分区域是白的，其他部分全黑……检查了无数遍自己的代码实在不明白到底是什么问题……orz，跪求大神帮助代码（出问题的thirframe窗体部分）如下：try{ if(ss==null){ ss= new ServerSocket(2016); System.out.println("KGC is ready!"); } while(true){ thirframe = new JFrame("KGC工作界面"); thirframe.setBounds(300,100,300,300); thirframe.setLayout(new FlowLayout()); end = new JButton("系统复位"); thirframe.add(end); end.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ try { ss.close(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } thirframe.dispose(); } }); JButton con = new JButton("正常继续"); thirframe.add(con); con.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ thirframe.dispose(); } }); SetupClient(ss); thirframe.setLocationRelativeTo(null); thirframe.setVisible(true); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } } catch(IOException e1){ e1.printStackTrace(); }
