Setting To, CC, and BCC fields


In the following example, we are going to show how to include the To, CC, and BCC fields in our email messages:

.... 
String[] arrTo = {}; 
String[] arrCC = {}; 
String[] arrBCC = {}; 
 
// setting to 
for (String to : arrTo) { 
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
} 
 
// setting cc 
for (String cc : arrCC) { 
    message.addRecipient(Message.RecipientType.CC, new InternetAddress(cc)); 
} 
 
// setting bbc 
for (String bcc : arrBCC) { 
    message.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc)); 
} 
.... 

As you see, we have used the addRecipient method to include multiple recipients to our email message, where the first parameter denotes whether this recipient is either To, CC, or BCC by using the Message.RecipientType.* constant.
