There are also unit tests to see if the Giant and Ogre classes are implemented correctly (particularly, the attack, takeDamage, and isAlive methods). Although the bulk of the grade will be how well the code handles all of the test cases, 20 points will be based on style. In particular, there are many weys to solve this using simple variables, but I am also interested in how well structured the code is using the supplied classes. Here are some things I will look for 5 points: Does the code use the getter/setter (accessor/mutator] methods to adjust the data fields and the other methods (particularly attack and takeDamage] to manage the battle? 5 points: Is the code well commented with proper header comments and inline comments? 5 points: Did you use good, meaningful method names and variable names? 5 points: Is the code well indented?

Answer 1

This is a really lengthy question so i will answering as much as i can (due to time limit)

First we have to create the monster class.

public class Monster {

double health;

double strength;

public void Monster(){

double health= 0;

double strength =0;

}

public void Monster(double health, double strength){

this.health = health;

this.strength = strength;

}

// Getters - getHealth and getStrength

public double getHealth(){

return health;

}

public double getStrength(){

return strength;

}

//Setter - setHealth and set Strength

public double setHealth(double newHealth){

this.health = newHealth;

return health;

}

public double setStrength(double newStrength){

this.strength = newStrength;

return strength;

}

public double attack(){

return health;

}

public double takeDamage(double damage){

return (health - damage);

}

public boolean isAlive(){

if(health>0)

return true;

else

return false;

}

Comment appropriately where ever it is required. In the class basically we have initialized the the healtha and strength variables which is the data. After that the functions are declared i.e. the getter , setters , attack(), takeDamage(), isAlive().

If you look at the other class like Giant and Ogre these class have almost similar data functions. So thats were the inheritance comes into play. extends keyword is used to inherit from the base class. Using inheritance we can use the data and functions in of the base class class in subclass ( to which it is extended).

Here Monster is the base class and Giant and Ogre are the subclasses of Monster class.

Here is Giant class

public class Giant extends Monster{
  
   public void Giant(){
       health = 1000.0;
       strength = 20.0;
   }
   @Override
   public double attack(){
       return (strength*health/1000);
      
   }

}

We can see that attack function of Giant is different from the base Monster class. So for that we override the attack() method in Giant class . Similarly we can create Ogre class . Here please keep in mind that  there will a extra variable totalHits( int totalHits; ) which has to declared first and also the attack function has to be overridden.

Then comes the main function Battle. This function will contain the main method.

Inside the main function we first the get input ( The number of giants that is going to fight).

For that we can use the scanner function to the input from keyboard.

Scanner s= new Scanner(System.in);

int n = s.nextInt();

the variable n will contain the number of giants. Now we have to loop n times as the giants will all die in the end.

You can use any loop.

For easiness i'm using for loop

for( i =1; i<=n; i ++){

//all the logic of the program goes here

}

We have create an object of Giant and Ogre for simulating the battle.

Giant g = new Giant(); // Creates a giant

similarly create an object of Orge o.

now simulating the battling is basically passing the values.
Orge will continue to fight till the giant die . So we have create another loop inside the for loop

while( g.isAlive ){

}

When a giant attacks an Orge we pass the Giant attackdamage to Orge's Damage.

o.setHealth(o.takeDamage(g.attack()))

similarly when ogre attacks a giant.

when o.isAlive becomes false the ogre die and a new ogre is created.( create a new Ogre object)

This continues till all Giants are dead.

Add the print statements as necessary.

Please let me know if you questions as time is short to answer the question completely. I can explain further.
