In this exercise you're playing a role-playing game named "Wizard and Warriors," which allows you to play as either a Wizard or a Warrior.

There are different rules for Warriors and Wizards to determine how much damage points they deal.

For a Warrior, these are the rules:

• Deal 6 points of damage if the fighter they are attacking is not vulnerable
• Deal 10 points of damage if the fighter they are attacking is vulnerable

For a Wizard, these are the rules:

• Deal 12 points of damage if the Wizard prepared a spell in advanced
• Deal 3 points of damage if the Wizard did not prepare a spell in advance

In general, fighters are never vulnerable. However, Wizards are vulnerable if they haven't prepared a spell.

You have six tasks that work with Warriors and Wizard fighters.

1. Describe a fighter

Override the toString() method on the Fighter class to return a description of the fighter, formatted as "Fighter is a <FIGHTER_TYPE>".

Fighter warrior = new Warrior();
warrior.toString();
// => "Fighter is a Warrior"

2. Make fighters not vulnerable by default

Ensure that the Fighter.isVulnerable() method always returns false.

Fighter warrior = new Warrior();
warrior.isVulnerable();
// => false

3. Allow Wizards to prepare a spell

Implement the Wizard.prepareSpell() method to allow a Wizard to prepare a spell in advance.

Wizard wizard = new Wizard();
wizard.prepareSpell();

4. Make Wizards vulnerable when not having prepared a spell

Ensure that the isVulnerable() method returns true if the wizard did not prepare a spell; otherwise, return false.

Fighter wizard = new Wizard();
wizard.isVulnerable();
// => true

5. Calculate the damage points for a Wizard

Implement the Wizard.damagePoints() method to return the damage points dealt: 12 damage points when a spell has been prepared, 3 damage points when not.

Wizard wizard = new Wizard();
Warrior warrior = new Warrior();

wizard.prepareSpell();
wizard.damagePoints(warrior);
// => 12

6. Calculate the damage points for a Warrior

Implement the Warrior.damagePoints() method to return the damage points dealt: 10 damage points when the target is vulnerable, 6 damage points when not.

Warrior warrior = new Warrior();
Wizard wizard = new Wizard();

warrior.damagePoints(wizard);
// => 10
