@Override錯誤

Question

你好傢伙即時嘗試發送電子郵件到我的電子郵件帳戶，但是當我把這個代碼存在與@Override錯誤，當我把它說我要添加時，我添加它，然後說我來仔細閱讀，並始終錯誤...：/ 這裏是代碼：

String username = Username.getText(); 
    String password = Password.getText(); 
    final String username2 = "stefanrafaa@gmail.com"; 
    final String password2 = "my pass"; 
    try { 
     File folder = new File(username); 
     File file = new File(folder, username + ".txt"); 
     FileReader freader = new FileReader(file); 
     BufferedReader breader = new BufferedReader(freader); 
     String line = breader.readLine(); 
     String[] parts = line.split("="); 
     String key = parts[0].trim(); 
     String value = parts[1].trim(); 
     if (key.equals("Password") && value.equals(password)) { 
      showError2(true); 
      new Thread(new Start(this)).start(); 
      LabelInfo.setForeground(Color.green); 
      LabelInfo.setText("Password Accepted"); 
     } else { 
      LabelInfo.setText("Wrong password"); 
      showError(true); 
     } 
    } catch (Exception ex) { 
     System.out.println("Exception: " + ex.getMessage()); 
     LabelInfo.setForeground(Color.red); 
     LabelInfo.setText("User doesn't exist"); 
     showError(false); 
     showError2(false); 
    } 

    Properties props = new Properties(); 
    props.put("mail.smtp.auth", "true"); 
    props.put("mail.smtp.starttls.enable", "true"); 
    props.put("mail.smtp.host", "smtp.gmail.com"); 
    props.put("mail.smtp.port", "587"); 

    Session session; 
    session = Session.getInstance(props, new javax.mail.Authenticator() { 
     @Override 
     protected PasswordAuthentication getPasswordAuthentication() { 
      return new PasswordAuthentication(username2, password2); 
     } 
    }); 

    try { 
     //Session session = null; 

     Message message = new MimeMessage(session); 
     message.setFrom(new InternetAddress("stefanrafa0@gmail.com")); 
     message.setRecipients(Message.RecipientType.TO, 
       InternetAddress.parse("stefanrafaa@gmail.com")); 
     message.setSubject("Testing Subject"); 
     message.setText("Dear Mail Crawler," 
       + "\n\n No spam to my email, please!"); 

     Transport.send(message); 

     System.out.println("Done"); 

    } catch (MessagingException e) { 
     throw new RuntimeException(e); 
    }

遠投：你已經導入了錯誤類型的PasswordAuthentication（確保它是「javax.mail.PasswordAuthentication」）。
