9. loginFrame.setSize(300,200);
10. loginFrame.setTitle("QQ2014");
11. loginFrame.setLocationRelativeTo(null);
12. //創建流式分布對象
13. FlowLayout layout=new FlowLayout();
14. loginFrame.setLayout(layout);
16. //創建賬戶名，密碼和輸入框
17. JLabel user=new JLabel("賬號：");
18. JLabel passWord=new JLabel("密碼：");
19. final JTextField named=new JTextField(20);

32. String password=password2.getText();
33. if("zhaoxin".equals(name)&&"123".equals(password))
