Question

Please help me with this question.

Im not sure how to implement the inform and returnDuplicate methods.

package studentCode;

public class BattleCow implements Battleable {
  
   private String name;
   private int strength;
   private int levelUps;
   private int victoriesSinceLevelUp;

/**
   * Method that takes the outcome of a battle and increments the level
   * if the number of victories has passed the threshold or sets the
   * strength to 0 if the outcome was a loss. We define "passed the
   * threshold" as meaning the victories equals or exceeds the threshold.
   * Also, note that the drop in strength level is not true for all
   * things that implement Battleable.
   * @param outcome the outcome of the battle in which this BattleCow was
   * involved
   * @return true if the outcome conveyed caused a level-up
   */
   public boolean inform(Universe.Outcomes outcome) {
       throw new RuntimeException("You must implement this!");
   }

  
  
  
   /**
   * Method to create an independent copy of the BattleCow.
   * @return independent copy of the BattleCow
   */
   public Battleable returnDuplicate() {
       throw new RuntimeException("You must implement this!");
   }

Within a seperate class, there are three outcomes: {WIN, LOSE, DRAW} and the threshold = 17.

public class Universe {

   public static enum Outcomes { WIN, LOSE, DRAW }
  
   public static int THRESHOLD = 17;
  
   public static Battleable fight(Battleable player1, Battleable player2) {
       int result =
               player1.getLevel()*player1.getStrength()
               -
               player2.getLevel()*player2.getStrength();
      
       if (result < 0) {
           player1.inform(Outcomes.LOSE);
           player2.inform(Outcomes.WIN);
           return player2;
       }
      
       if (result > 0) {
           player1.inform(Outcomes.WIN);
           player2.inform(Outcomes.LOSE);
           return player1;
       }
      
       player2.inform(Outcomes.DRAW);
       player2.inform(Outcomes.DRAW);
      
       return null;
   }
  
}

Thank you.

Explanation / Answer

//u didn't specify the interface Battleable therefore my solution is containing some error becoz Batteable is not defined

//Define the interface Battleable and code will work perfectly

package studentCode;
public class BattleCow implements Battleable
{
  
private String name;
private int strength;
private int levelUps;
private int victoriesSinceLevelUp;

/**
* Method that takes the outcome of a battle and increments the level
* if the number of victories has passed the threshold or sets the
* strength to 0 if the outcome was a loss. We define "passed the
* threshold" as meaning the victories equals or exceeds the threshold.
* Also, note that the drop in strength level is not true for all
* things that implement Battleable.
* @param outcome the outcome of the battle in which this BattleCow was
* involved
* @return true if the outcome conveyed caused a level-up
*/
public boolean inform(Universe.Outcomes outcome) //Outcomes is static so we access it by class name
{
//throw new RuntimeException("You must implement this!");
if(victoriesSinceLevelUp>Universe. THRESHOLD)
{
   levelUps++;
  
}
  
if(outcome==Universe.Outcomes.LOSE)
{
   strength=0;
}
  
}
  
  
  
/**
* Method to create an independent copy of the BattleCow.
* @return independent copy of the BattleCow
*/
public Battleable returnDuplicate()
{
//throw new RuntimeException("You must implement this!");
BattleCow c=new BattleCow();
return c;
  
}
}   

//Within a seperate class, there are three outcomes: {WIN, LOSE, DRAW} and the threshold = 17.
public class Universe
{
public static enum Outcomes { WIN, LOSE, DRAW }
  
public static int THRESHOLD = 17;
  
public static Battleable fight(Battleable player1, Battleable player2)
{
int result =
player1.getLevel()*player1.getStrength()
-
player2.getLevel()*player2.getStrength();
  
if (result < 0) {
player1.inform(Outcomes.LOSE);
player2.inform(Outcomes.WIN);
return player2;
}
  
if (result > 0) {
player1.inform(Outcomes.WIN);
player2.inform(Outcomes.LOSE);
return player1;
}
  
player2.inform(Outcomes.DRAW);
player2.inform(Outcomes.DRAW);
  
return null;
}
  
}
