Email Message Program Between 2 Classes

I am trying to make a program that takes the information from the main args, and displays them as a email in another class when Java is run.

Ex.
From: PersonA
To: PersonB
Email message is here

I have gotten this far, but every time I append my "email.print()" into the next class, it never can print any of the Strings.

Main Args Class:

public class TestMessage {
public static void main(String[] args) {
Message email = new Message("Harry Morgan", "Rudolf Reindeer");
email.append("Dear so and so,");
email.append("It is my great pleasure to");
email.append("write you an email.");
email.append("");
