Answer 1

change

MailMessage MailMessage = new new MailMessage();

to

MailMessage mailMessage = new new MailMessage(); // object name start with small m because you are using it onward.

why don't you directly set the parameters in MimeMessage ? like

 MimeMessage message= new MimeMessage(session);
    message.setFrom("Sender Name");
    message.setFrom("xxx@gmail.com");
    message.setSubject("Maile Subject");
    message.setContent(rs.getString("Hi This is testing email"));
    //Rest of your code

   // and send
