JavaMail - отправка нескольких электронных писем в цикле

Мне было поручено написать приложение, которое отправит электронное письмо 1-3 получателям с 5 возможными вопросами опроса. Вопросы и получатели извлекаются из файла свойств, а количество отправленных сообщений электронной почты также хранится в этом файле.JavaMail - отправка нескольких электронных писем в цикле

Моя проблема заключается в том, что я не могу получить электронные письма для отправки с помощью этого кода, любые предложения?

Я бы рекомендовал читать на петлях в онлайн-учебниках Java. Все, что вам нужно знать, находится прямо здесь. –

Спасибо, я отправлю свой ответ, когда я его заработаю. –

Игнорируя всю неэффективность базовой кодировки, вам нужно будет более подробно объяснить, что вы подразумеваете под «не может получить электронные письма для отправки». Начните с этой записи [JavaMail FAQ для отладки] (http://www.oracle.com/technetwork/java/javamail/faq/index.html#debug). –

После нескольких экспериментов, я заметил, что 2 из 3, если заявления были вложены в первом, вызывая проваливаются.

Вот рабочий код:

** для цикла, чтобы проверить файл конфигурации, используя для чтения **

for(int i=0; i<noOfEmails; i++) 
     { 
      if(noOfEmails==1) 
      { 
       for(int j=0; j<noOfQuest; j++) 
       { 
        System.out.println("In Loop[" + j + "] : recipient1: "+ recipient1); 


        if(i==0) 
        { 
         message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipient1));        
        } 
        if(noOfQuest==1) 
        { 
         message.setText("Username: " + fName + " "+ sName + "\n" + 
              "Response 1: " + answers[0]);       
        }

Для всех, кто находится в замешательстве, "noOfEmails | noOfQuest" 2 переменные которые считываются из файла свойств.
