AdventureCharacter

Instructions

In the following quest, we will work with the same files and classes. You should keep them from one exercise to the following.

Create a file Character.java.

Create a public class named Character.
The class must contain three properties :

• maxHealth (int) : with a getter and no setter. This property is not updatable (final keyword).
• currentHealth (int) : with a getter and no setter.
• name (String) : with a getter and no setter. This property is not updatable (final keyword).

Create a constructor with two parameters (name and maxHealth) : the currentHealth is initialized with the value of maxHealth.

Override toString method, Must have the format <name> : <currentHealth>/<maxHealth>. If the currentHealth is 0, the format is <name> : KO.

Implement two methods :

• takeDamage, with an integer parameter, that will subtract the amount in parameter from currentHealth. currentHealth can't be lower than 0.
• attack, with a parameter of type Character, that will call takeDamage of the parameter with a default value : 9.

Usage

Here is a possible ExerciseRunner.java to test your function :

public class ExerciseRunner {

    public static void main(String[] args) {
        Character aragorn = new Character("Aragorn", 20);
        Character uruk = new Character("Uruk", 5);
        
        System.out.println(aragorn.toString());
        System.out.println(uruk.toString());
        
        aragorn.attack(uruk);

        System.out.println(uruk.toString());
        
        aragorn.takeDamage(12);

        System.out.println(aragorn.toString());
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner 
Aragorn : 20/20
Uruk : 5/5
Uruk : KO
Aragorn : 8/20
$
