1 Description of the Program In this assignment, you will write four java files, Message.java, MessageTester.java, Mailbox.java and MailboxTester.java, Stage 1: In the first file Message.java, create a class named Message that models an email message. It should contain the following: . Private instance variables sender, recipient, and messagetext . A default constructor that takes no inputs (set all members to an empty string) . A constructor takes all three inputs (sender, recipient and messagetext); Three getter methods to return each of three instance variables (accessor); . Three setter methods to change each of three instance variables (mutator . A method toString that makes the message into one long string like this: From: Harry Morgan To: Rudolf Reindeer This is my message.. . Stage 2: In the second file MessageTester.java, write code to test the methods that you write in the class of Message.java. Specifically: 1. Create two message objects using the constructor taking inputs. The inputs are from "messages0.txt. You can either read the file into message objects, or you can manually initialize the objects using the information from the file. 2. Print them out using toString) method 3. Set each object using setter methods (Inputs, e.g., CurrentSender1, CurrentRecipient1) 4. Display each object's information using getter methods. Your output should look like igureI
