3. The following is some code designed by J. Hacker for a video game. There is an Alien class to represent a monster and an AlienPack class that represents a band of aliens and how much damage they can inflict: class Alien { public static final int SNAKE_ALIEN = 0; public static final int OGRE_ALIEN = 1; public static final int MARSHMALLOW_MAN_ALIEN = 2; public int type; // Stores one of the three above types public int health; // 0-dead, 100-full strength public String name; public Alien (int type, int health, String name) { this.type = type; this.health = health; this.name = name; } } public class AlienPack { private Alien[] aliens; public AlienPack (int numAliens) { aliens = new Alien[numAliens]; } public void addAlien (Alien newAlien, int index) { aliens[index] = newAlien; } public Alien[] getAliens () { return aliens; } public int calculateDamage () { int damage = 0; for (int i=0; i < aliens.length; i++) { if (aliens[i].type==Alien.SNAKE_ALIEN) { damage +=10; // Snake does 10 damage } else if (aliens[i].type==Alien.OGRE_ALIEN) { damage +=6; // Ogre does 6 damage } else if (aliens[i].type== Alien.MARSHMALLOW_MAN_ALIEN) { damage +=1; // Marshmallow Man does 1 damage } } return damage; } } The code is not very object oriented and does not support information hiding in the Alien class. Rewrite the code so that inheritance is used to represent the dif- erent types of aliens instead of the \"type\" parameter. This should result in deletion of the \"type\" parameter. Also rewrite the Alien class to hide the instance variables and create a getDamage method for each derived class that returns the amount of damage the alien inflicts. Finally, rewrite the calculateDamage method to use getDamage and write a main method that tests the code.
