Instructions
In this exercise you're playing a role-playing game named "Wizard and Warriors" with your best friends. You are the Game Master, the person tasked with making the game world come alive for the players. A key aspect of this is describing the game to the players: what is a character's status, what the town they're visiting looks like, etc.
You have five tasks that have you describe parts of the game to the players.
1. Describe a character
Each character has a class, level and number of hit points and is described as: "You're a level <LEVEL> <CLASS> with <HIT_POINTS> hit points.".
Implement the GameMaster.describe method that takes a Character as its sole parameter and returns its description.
Character character = new Character();
character.setCharacterClass("Wizard");
character.setLevel(4);
character.setHitPoints(28);
new GameMaster().describe(character);
// => "You're a level 4 Wizard with 28 hit points."2. Describe a destination
Each destination has a name and a number of inhabitants and is described as: "You've arrived at <NAME>, which has <INHABITANTS> inhabitants.".
Implement the GameMaster.describe method that takes a Destination as its sole parameter and returns its description.
Destination destination = new Destination();
destination.setName("Muros");
destination.setInhabitants(732);
new GameMaster().describe(destination);
// => "You've arrived at Muros, which has 732 inhabitants."3. Describe the travel method
Characters can travel to a destination using one of two options:
- Walking, described as:
"You're traveling to your destination by walking." - On horseback, described as:
"You're traveling to your destination on horseback."
Implement the GameMaster.describe method that takes a TravelMethod as its sole parameter and returns its description.
new GameMaster().describe(TravelMethod.HORSEBACK);
// => "You're traveling to your destination on horseback."4. Describe a character traveling to a destination
When a character is traveling to a destination, this is described as a combination of the individual descriptions: "<CHARACTER> <TRAVEL_METHOD> <DESTINATION>".
Implement the GameMaster.describe method that takes a Character, a Destination and a TravelMethod as its parameters and return its description.
Character character = new Character();
character.setCharacterClass("Wizard");
character.setLevel(4);
character.setHitPoints(28);
Destination destination = new Destination();
destination.setName("Muros");
destination.setInhabitants(732);
new GameMaster().describe(character, destination, TravelMethod.HORSEBACK);
// => "You're a level 4 Wizard with 28 hit points. You're traveling to your destination on horseback. You've arrived at Muros, which has 732 inhabitants."5. Describe a character traveling to a destination without specifying the travel method
In the majority of cases, characters are traveling to a destination by walking.
For convenience, players are allowed to omit mentioning their travel method, in which case walking will be assumed to be the travel method.
Implement the GameMaster.describe method that takes a Character and a Destination as its parameters and return its description.

destination.setInhabitants(732);
