Problem Description
Peter Pan needs a reliable translator to encode messages to evade his nosy pirate adversaries, and he
needs your help! You will implement a translation system that can handle his diverse linguistic needs. To
do that, you will write three classes (the name of each is bolded below).
The Message class is at the core of the translation system. A Message stores a message and the
dialect it's encoded into. A Dialect enum defines all supported dialects, where each dialect has its
own set of rules governing the translation of messages. Additionally, the Message class maintains a
running count of how many messages have been translated to each dialect at any point in time.
Message exposes a public translate method that translates the original message into its specified
dialect. It defines other private methods that handle the translation logic for each specific dialect. Note
that a Message should not be considered translated until the first call to the translate method on that
object.
Message also exposes a method that returns the counts of messages translated into each dialect
across all instances.
The Peter Pan class is the driver program for the translation system. It's responsible for creating
messages with various dialects and displaying the translations along with other information. It enables
live input from the user for message content and dialect selection, offering a more engaging and
interactive experience.
Lastly, for this homework and all future ones, we will require you to Javadoc your code. The Checkstyle
section toward the end of the document discusses this some.

Solution Description
In the interest of encapsulation, data members for each of the following classes should only be
accessible from other classes using getters and/or setters where needed. The described methods and
constructors for this assignment should be public. It is OK to write private helper methods for your
classes, however.
Your solution will consist of three files:
Dialect.java
Message.java
Peter Pan.java
Dialect.java
Defines an enum that enumerates three dialects: PIRATE, ELMER_FUDD and COMPUTER.
Message.java
The Message class is the central component of the translation system, managing individual messages
by encapsulating their dialect and content. To instantiate a message, a client must provide the dialect
and original string message (in that order). Message should include methods to translate messages
into each of its three supported dialects respectively, while allowing the user only to interface with it
through the general translate method. (Think about what that means.)
A Message has the following attributes:
1. A dialect
2. The message (two versions)
a. Holds the original, unmodified message before translate has been called
b. Holds the translated, modified message once translate has been called
3. A true/false value specifying whether translate has been called yet for this message
Further, the Message class will track the values below across all instances:
1. The count of messages translated into Elmer Fudd dialect
2. The count of messages translated into Pirate dialect
3. The count of messages translated into Computer dialect
Each of the counts will start at 0.
You should initialize all instance variables in the constructor (consider hat value the true/false flag
should initially assume).
