请大侠看看这段代码有什么错误？

Question

String pass=new String(pwd.getPassword());
if(pass.equals("ABC"))

Answer 1

Public void actionPerformed(ActionEvent evt) 
       { 
        Object src = (Object)evt.getSource();//Object为你定义的按钮类型:Button或是JButton 
               if (src == n1) // 已定义好的按钮 
                  { 
                   if(pwd.toString().equals("ABC"))         // pwd 是已定义的密码域,字符串的比较应该用equals,否则会得出相反的结果  
                      System.out.println("密码正确"); 
                   else  
                      System.out.println("密码错误"); 
                  } 
        repaint(); 
        }
