RANGEDWEAPON CLASS 2

Topics

• Object array
• Polymorphism
• Inheritance

TASK – PART 1 – SETUP

You will need to copy an paste the following classes from the RangedWeapon class solution and work sections.

· Weapon (from the work section)

· Projectile (from the solution section)

· RangedWeapon (from the solution section)

TASK – PART 2 – MORE SETUP

Copy and paste the following Tester class. (Feel free to rename it Tester2 if Tester is already taken.)

Run the file to see what happens.

public class Tester

{

public static void main(String[] args)

{

Weapon w1 = new Weapon("Sword",6,8,0);

System.out.println(w1);

Projectile dart = new Projectile("Dart", 1);

RangedWeapon w2 = new RangedWeapon("Blowpipe",2,3,0,dart);

System.out.println(dart);

System.out.println(w2);

Projectile arrow = new Projectile("Arrow", 2);

RangedWeapon w3 = new RangedWeapon("Bow",3,4,0,arrow);

System.out.println(arrow);

System.out.println(w3);

Weapon w4 = new Weapon("Axe",7,9,0);

System.out.println(w4);

Weapon w5 = new Weapon("Spear",10,11,0);

System.out.println(w5);

Weapon w6 = new Weapon("Morning Star",5,10,0);

System.out.println(w6);

Projectile sarrow = new Projectile("Silver Arrow", 3);

RangedWeapon w7 = new RangedWeapon("Crossbow",3,4,0,sarrow);

System.out.println(w7);

Weapon w8 = new Weapon("Dagger",2,3,0);

System.out.println(w8);

//Example of damage done by w6 on three occasions.

System.out.println(w6.getDamageAmount());

System.out.println(w6.getDamageAmount());

System.out.println(w6.getDamageAmount());

}

}

TASK – PART 3 – POLYMORPHISM

In the main function from the above Tester class, do the following:

· Add a Weapon array of size 8.

· Place the 8 weapons (w1 to w8) into the array.

· Simulate a round of attack using each weapon. Use a loop. Output the damage done by each weapon and the total damage from the round.

· Place the above loop inside another loop to simulate 20 rounds of attack.

· Total the entire damage done and output it to screen.
