Design a class Message that models an email message. A message has a recipient, a sender , and a message text. Support the following methods:
1) A constructor that takes the sender and recipient
2) A method append that appends a line of test to the message body
3) A method toString that makes the message into one long string like this: "From: Harry MorgannTo: RudoIf Reindeer/n....."
Write a program using this class to make a message and print it.
