java中添加按钮并添加响应事件的方法(推荐)

</pre><pre name="code" class="java">private Button LogInbtn = new Button("登陆"); 
final static JFrame buyerpagemain = new JFrame(); 
final Container contentPane = buyerpagemain.getContentPane(); 
contentPane.add(LogInbtn);// 登陆按钮 
    LogInbtn.setBounds(690, 12, 40, 30); 
    LogInbtn.setBackground(Color.green); 
    LogInbtn.addActionListener(new ActionListener() { 
      public void actionPerformed(ActionEvent e) { 
        new LoginMain("登陆"); 
 
        //buyerpagemain.dispose(); 
      } 
    }); 

 public class LoginMain extends JFrame { 
    public static void main(String[] args) { 
    new LoginMain("登陆"); 
  } 
}
