java iterate through properties file
Question
I have a project to send emails via a Java Application. I have almost everything working, I just need to be able to configure the number of emails I send.
I have all of the email addresses in a Properties File. The application spec requires me to set a value in this file that will determine the number of emails to send. Here is an example of my properties file, in the hope that this helps:
email1=tom@foo.com
email2=jerry@foo.com
email3=spike@foo.com
iterate=1 //this is the value that needs to be changed
in order to decide the number of emails to send.
In my application code, I have the following:
Application
Properties props = new Properties();
String to = props.getProperty("to");
String from = props.getProperty("from");
String host = props.getProperty("host");
String port = props.getProperty("port);
props.setProperty("mail.smtp.host", host);
props.setProperty("mail.smtp.port", port);
try
{
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject("<subject goes here>");
message.setText(<body goes here>);
Transport.send(message);
}

I think you put all your email id against single key
emails=tom@foo.com,jerry@foo.com,spike@foo.com
Then read this emails string and split it into to array.
Then read iterate , and execute your for loop on email array upto no of iterate present in your properties file.
Edited
If this email id's for to emails
String emails = props.getProperty("emails);
String iterate = Integer.valueOf(props.getProperty("iterate));
String arr[]= emails.split(",");
String toArr[] = new String[iterate];
System.arraycopy(arr, 0, toArr, 0, iterate);
now you have toArr array, using this toArr send your email's
