### Instructions
|
||
|
|
|
||
|
|
Let's change some things : make the `Character` as `abstract`. You can now try to instantiate a Character object, it will fail :)
|
||
|
|
|
||
|
|
Change the `attack` and `takeDamage` methods : put them as `abstract` too.
|
||
|
|
|
||
|
|
Now, if you try to launch some example, it will fail. Indeed, you need to implement both methods in all subclasses. Do this as follow :
|
||
|
|
|
||
|
|
Remember that in all cases, the `currentHealth` should not be lower than 0.
|
||
|
|
|
||
|
|
* For Monster class :
|
||
|
|
* the `attack` method should deal 7 damages to the character as parameter.
|
||
|
|
* the `takeDamage` method should take 80% of all the damages, rounded to the inferior integer.
|
||
|
|
* For the `Sorcerer` class :
|
||
|
|
* the `attack` method should heal itself (using the `heal` method) then deal 10 damages to the character as parameter.
|
||
|
|
* the `takeDamage` method should take all the damages.
|
||
|
|
* For the `Templar` class :
|
||
|
|
* the `attack` method should heal itself (using the `heal` method) then deal 6 damages to the character as parameter.
|
||
|
|
* the `takeDamage` method should take the damage as parameter minus the shield value.

### Usage
|
||
|
|
|
||
|
|
Here is a possible ExerciseRunner.java to test your function :
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class ExerciseRunner {
|
||
|
|
|
||
|
|
public static void main(String[] args) {
|
||
|
|
Templar alistair = new Templar("Alistair", 18, 2, 4);
|
||
|
|
Sorcerer morrigan = new Sorcerer("Morrigan", 21, 5);
|
||
|
|
Monster dragon = new Monster("Dragon", 12);
|
||
|
|
|
||
|
|
dragon.attack(alistair);
|
||
|
|
dragon.attack(morrigan);
|
||
|
|
|
||
|
|
alistair.attack(dragon);
|
||
|
|
morrigan.attack(dragon);
|
||
|
|
|
||
|
|
System.out.println(Character.printStatus());
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
and its output :
|
||
|
|
```shell
