### 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 contains 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 maxHealth value.
|
||
|
|
|
||
|
|
Rewrite the `toString`, that will 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 remove the amount in parameter to the `currentHealth`. The current health can't be lower than 0.
|
||
|
|
* `attack`, with a `Character` parameter, that will call `takeDamage` of the parameter with a default value : `9`.

||

### Usage
|
||
|
|
|
||
|
|
Here is a possible ExerciseRunner.java to test your function :
|
||
|
|
|
||
|
|
```java
|
||
|
|
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 :
|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
|
||
|
|
Aragorn : 20/20
|
||
|
|
Uruk : 5/5
|
||
|
|
Uruk : KO
|
||
|
|
Aragorn : 8/20
|
||
|
|
$
|
||
|
|
```
|
