General

Detailed explanation of inheritance can be found at Inheritance. The whole inheritance concept has a lot to do with the concepts around overriding.

1. Describe a Fighter.

• In Java, the toString() method is actually present inside the Object class (which is a superclass to all the classes in Java). You can read more about it here.

• To override this method inside your implementation class, you should have a method with same name i.e toString() and same return type i.e String.

2. Making Fighters not vulnerable by default.

• Consider having a method isVulnerable() inside the Fighter class which states vulnerability of the fighter, return false to make it non-vulnerable by default.

• This can than be overridden by any child class(the class extending Fighter), according to its requirements.

• Again the overriding concept will come handy.

3. Allowing wizards to prepare a spell.

• Preparing a spell can only be done by a wizard. So, it makes sense to have this property defined inside the Wizard class.

• Create prepareSpell() method inside Wizard class.

• Remember : Parent class(here Fighter) has no access to the properties of the child class(for example, Wizard)

4. Make Wizards vulnerable when not having prepared a spell

• Override the isVulnerable() method in the Wizard class to make Wizards vulnerable if they haven't prepared a spell.

5. Calculate the damage points for a Wizard

• Use a conditional statement to return the damage points, taking into account the value of the prepare spell field.

6. Calculate the damage points for a Warrior

• Use a conditional statement to return the the damage points, taking into account the vulnerability of the target.
