This way you allow the user of the '''Message''' class (you will use it inside the '''Main''' class, therefore you will be such a user) to call a method that returns the formatted string, ready to be displayed by any print method of the ''System.out'' object. Add to the '''Message''' class a method of your own (give it whatever name you like,  such as ''print'', or ''read'') that returns the sender's name and the message body as a single string formatted as required. Then, add another method that does exactly the same thing but whose declaration is <code style="color:green;">public String toString()</code>.
 * Add to this package another class called '''Main''', which should contain only the '''main''' method, that instantiates three objects of type '''Message''' and then displays for each of them their formatted string on the screen using one of the System.out print methods, first with a single String argument, the String returned by your method from Message class, and then with the object's reference as its sole argument.
