How to respond to the prompt?

Question

Hello Friends, I have a class that sends mail. It is petty cool but now I want it to send e-mail without me entering the info. So, when the program prompts To: I can have a program that fills that out for me. And Then when it asks for a message, I can have my predefine text input and when it is done it types a point. I think this is simple but I really have no clue how to do this, Thanks in advance... I have cut and past how this program looks when you are running it.
somecomputer/someuser>java SendMail
To: [email protected]
Connecting...
Enter the message. End with a '.' on a line by itself.
Hello!
Message sent.
somecomputer/someuser>

I wrote this code but it seems to work in windows but it hangs in Unix. Can someone help me, thanks.
import java.io.*;
public class testSendMail
     public static void main(String[] args)
          String [] email = {"[email protected]" , "Hello!" , "."};
          SendMail  sm = new SendMail();
          sm.main(email);
}
