Question

It's the end of the semester and I have a big project to do. It's a multi-class Battleship game. However, I seem to be having problems with the BattleBoard.java class, more specifically the public boolean isShipSunk(int shipIndex), the public ArrayList getAllSunkenShips(), and the public HitStatus getHitStatus(int row, int col) methods. I simply have no idea what they need to look like. Here are the instructions

public boolean isShipSunk(int shipIndex): returns true if the ship at the specified index in the array has been sunk by enemy fire.

public ArrayList<Ship> getAllSunkenShips(): returns an ArrayList of Ships that have been sunk by enemy fire.

public HitStatus getHitStatus(int row, int col): returns the HitStatus of the Square located at the specified row and column. Throw an IllegalArgumentException if row < 0, col < 0, row >= number of rows, or col >= number of columns.

For reference, this is the HitStatus enum from my Square class

public enum HitStatus {

HIT, //hit and occupied

MISSED, //hit and unoccupied

NOT_YET_HIT// not yet hit

}

I need to know exactly what these methods are supposed to look like

Here is a link to my code if you need to see it

Explanation / Answer

Please find the function definations as below:

public boolean isShipSunk(int shipIndex)
{
   if(ships[shipIndex].isSunk())
       return True;
   else
       return False;
}

public ArrayList<Ship> getAllSunkenShips()
{
   ArrayList<Ship> sunkShip;
   for(int i = 0; i < numberOfShips; i++)
   {
       if(ships[i].isSunk())
           sunkShip.add(ships[i]);
   }
   return sunkShip();
}
