Below is the code given. Your job is to add a new class that utilizes the Decorator Pattern. Code must continue to be done in java, and the Warrior and Builder Classes must remain abstract and untouched. Create a new decorator class named ArmoredWarriorDecorator which has the defense field multiplied by $2.$ This change should affect all method calculations. You can confirm it is working correctly by running this line of code.

Warrior warrior $=$ new ArmoredWarriorDecorator$($new AggressiveWarrior.Builder$(1).$defense$(10).$build$())$;

public abstract class Warrior $\{$

private final int level;

private final int attack;

private final int defense;

protected Warrior$($Builder builder$)\{$

this.level $=$ builder.level;

$\}$
