用JAVA做一个登陆窗口要输入账号和密码密码输错3次就提示被锁定要有退出按钮

这个是用java se 做的  代码不复杂，就是 MyEclipse自动生成了一些页面布局的代码，对程序没什么影响，如果你不喜欢或者嫌复杂稍微改一下就可以了，因为大半夜了，布局我也不可能给你手写去，挺麻烦的。见谅。怎么还要用云盘呀 干脆再给你贴上来吧。就是布局那块 有点乱。

import javax.swing.JOptionPane;
public class Login extends javax.swing.JFrame {
 int flag = 3;
 private java.awt.Button button1;
 private java.awt.Button button2;
 private javax.swing.JPasswordField jPasswordField1;
 private java.awt.Label label1;
 private java.awt.Label label2;
 private java.awt.TextField textField1;

 /** Creates new form Login */
 public Login() {
  flag=3;
  initComponents();
  this.setVisible(true);
  button1.setEnabled(true);
 }

 //这个方法里的代码是 工具自动生成的窗体布局代码。直接用就可以，如果你不喜欢你就自己稍微修改一下就可以。直接运行一点问题没有。
 private void initComponents() {

  label1 = new java.awt.Label();
  textField1 = new java.awt.TextField();
  label2 = new java.awt.Label();
  jPasswordField1 = new javax.swing.JPasswordField();
  button1 = new java.awt.Button();
  button2 = new java.awt.Button();

  setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

  label1.setName("");
  label1.setText("用户名：");
