Java - 如何驗證用戶名和密碼

Question

如何驗證電子郵件（Yahoo，Gmail，Hotmail和AOL）的用戶名和密碼？ 哪裏應該把認真的auth電子郵件？

這是我的代碼

public class AuthMail 
{ 
    public static void authEmail() 
    { 
     if(LoginDialog.t_Email.getText().isEmpty()) 
     { 
      Util.printErrorMessage("Plase Enter an Email Address"); 
      JOptionPane.showMessageDialog(null, "Plase Enter an Email Address", "Error", JOptionPane.ERROR_MESSAGE); 
     } 
     else if(LoginDialog.p_Password.getText().isEmpty()) 
     { 
      System.out.println("Plase Enter Your Password"); 
      JOptionPane.showMessageDialog(null, "Plase Enter Your Password", "Error", JOptionPane.ERROR_MESSAGE); 
     } 
     else if(Util.getMailType().equals("GMail")) 
     { 
      System.out.println("Logging..."); 
      System.out.println("Attempting connection to GMail..."); 
     } 
     else if(Util.getMailType().equals("Yahoo")) 
     { 
      System.out.println("Logging..."); 
      System.out.println("Attempting connection to Yahoo..."); 
     } 
     else if(Util.getMailType().equals("Yahoo")) 
     { 
      System.out.println("Logging..."); 
      System.out.println("Attempting connection to Hotmail..."); 
     } 
     else if(Util.getMailType().equals("AOL")) 
     { 
      System.out.println("Logging..."); 
      System.out.println("Attempting connection to Aol..."); 
     } 
     else if(Util.getMailType().equals("Unknown")) 
     { 
      System.out.println("Mail Type Unknown"); 
      int var1 = JOptionPane.showConfirmDialog(null, "Email Type Unknown. Did you want to try again?", "Error", JOptionPane.YES_NO_OPTION); 
      if(var1 == JOptionPane.NO_OPTION) 
      { 
       System.exit(0); 
      } 
     } 
    } 

}

注：Util.class是由自己創造。

使用接受主機，用戶和密碼的Store.connect方法。你正在收集用戶名和密碼。主機名將在您的「if」的每個分支中有所不同。您將在JavaMail FAQ中找到常見服務的主機名。
