## AdventureSorcerer

### Instructions

We will now implement our first interface through a new class : `Sorcerer` in a file named `Sorcerer.java`.

This class implements the `Healer` interface and inherits from `Character`. It has a new attribute : an integer `healCapacity`.

It has a constructor with three parameters : 
* `name`,
* `maxHealth`
* `healCapacity`

From the `Healer` interface : 
* `getHealCapacity` returns the property `healCapacity`
* `heal` add `healCapacity` to the currentHealth of the `Character` in parameter. Beware that the `currentHealth` can't be greater the `maxHealth`. You may need to change the accessibility of the `currentHealth` param in the `Character` to be able to update the value.

You will override the `toString` method with the following format : `<name> is a sorcerer with <currentHealth> HP. It can heal <healCapacity> HP.`
If it's `currentHeal` is equal to 0, the format is `<name> is a dead sorcerer. So bad, it could heal <healCapacity> HP.`

### Usage

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

```java
public class ExerciseRunner {

    public static void main(String[] args) {
        Sorcerer gandalf = new Sorcerer("Gandalf", 20, 5);
        Character frodon = new Character("Frodon", 20);
        Sorcerer saroumane = new Sorcerer("saroumane", 10, 3);

        Character.fight(frodon, saroumane);
        
        gandalf.heal(frodon);

        System.out.println(Character.printStatus());
    }
}
```

and its output :
```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner 
------------------------------------------
Characters currently fighting : 
 - Gandalf is a sorcerer with 20 HP. It can heal 5 HP.
 - Frodon : 16/20
 - Saroumane is a dead sorcerer. So bad, it could heal 3 HP.
