Module 7 - Game Character Lab

🎯 Objective

In this lab, you will create a simple RPG (Role-Playing Game). We have different types of characters in our game, each with different abilities and attributes.

Part 1: Character Class (Superclass)

Create a class named Character which will serve as the superclass for all types of characters in the game.

This class should have the following properties:

• name: A String representing the character's name.

• level: An int representing the character's level.

• health: An int representing the character's health.

This class should have the following methods:

• attack(): Prints a message that the character is attacking.

• defend(): Prints a message that the character is defending.

• Getter and setter methods for each property.

Part 2: Create Subclasses

Create two subclasses of Character: Warrior and Mage.

The Warrior class should have the following additional properties:

• strength: An int representing the Warrior's strength.

The Mage class should have the following additional properties:

• magic: An int representing the Mage's magic power.

Each subclass should override the attack() method to display a unique attack style. For example, a Warrior might attack with a sword, while a Mage might use a spell. They should also have getter and setter methods for each new property.

Part 3: Implement an Interface

Create an interface named SpecialAbility. This interface should define a method called useAbility().

Next, implement the SpecialAbility interface in the Warrior and Mage classes. In the useAbility() method, print a message that describes the character's special ability. For example, a Warrior might have a "Berserker Rage" ability, while a Mage might have a "Time Warp" ability.

Part 4: Main Class

In a main method, create instances of your Warrior and Mage classes, set their properties, and call their methods to demonstrate that everything is working as expected. This should include the useAbility() method.

Deliverables:

1. Character.java

2. Warrior.java

3. Mage.java

4. SpecialAbility.java

5. Main.java

Good luck and happy coding!

Note on Lab:

You might be wondering why we did not just have a useAbility() method in our Character class. Reasons are:

1. Flexibility and Decoupling: Using an interface allows for more flexible and decoupled design. Classes can implement multiple interfaces, enabling them to have a variety of behaviors without being tied to a specific class hierarchy. In contrast, a class can only extend one class, which can lead to a more rigid and tightly coupled design.

2. Evolution of Design: As the game evolves, you might want to add new types of characters with different special abilities (different interfaces). If you use an interface for special abilities, you can easily add new character types that implement this interface without modifying the existing class hierarchy or affecting other character types.

3. Specificity of Role: The SpecialAbility interface specifically defines the role of having a special ability. It's a clear declaration that any class implementing this interface will provide a particular functionality. This is more specific and targeted than an abstract method in a superclass, which might imply that all subclasses have or need this method's implementation.

4. Encouraging Modular Design: Using interfaces promotes thinking in terms of modular, interchangeable components. This approach fosters designing systems where individual parts can be developed, tested, and debugged independently, then combined to create complex functionalities.

Using an interface like SpecialAbility in this lab helps in defining clear, flexible, and modular contracts for what characters in the game can do, particularly focusing on their unique abilities, while also allowing for the evolution and expansion of the game's character system.
