Nim Game complications

I'm supposed to generate a random number of piles, with a random number of coins in each pile. I'm having trouble figuring out how to generate the random number of coins in each pile, and i don't understand why coins[] should be an array. If my logic isn't completely off...shouldn't piles be an array? I usually do alright with my projects...but this one has me stumped...

There are two classes being used. Here are the req's: Game class The Game class stores the game state and requires at least two private variables: private int numPiles; // the number of piles of coins private int [] coins; // the coins in each pile

A no arg constructor should init thegame with a random number of piles and coins. A two arg constructor should init the game with a specified number of piles and a predefined array of coins in each pile. PlayGame The PlayGame class has its own private data:

1. Player names

2. An int to keep track of Whose turn it is

3. The Game object

4. A Scanner object to accept input

The only constructor is the default constructor, which should

• ask each player their name

• set turn to 1

• Init the Game by either

o Ask how many piles in the game ( num piles)

o Ask how many stick per pile and build an array int piles[] game = new Game(numPiles, piles) or

Use the default constructor to setup a random game game = new Game()

You should also have a method public void play() that plays the game until no coins remain. Remember to switch turn back and forth between player 1 and 2. Here's all i have so far...

import java.util.Scanner;
import java.util.Random;

public class PlayGame
{

   private Scanner scan = new Scanner(System.in);
   private int takeCoin;
   boolean whoseTurn;

   //Gets players names
   private void getPlayers()  
   {
      System.out.println("Welcome to the Rob Mr. Monopoly Game.");

      System.out.println("First player, what is your name?");
      String firstPlayer = scan.nextLine();
      System.out.println();

      System.out.println("Second player, what is your name?");
      String secondPlayer = scan.nextLine();
      System.out.println();   
   }

   //Gets number of coins to take
   private void takingCoins()
   {
      takeCoin = scan.nextInt();

      //Doesn't allow invalid input
      if(takeCoin < 1 || takeCoin > 10)
      {
         System.out.println(takeCoin + "? You're already stealing,"
         + " please learn how to count.");
      }

   }

   private void getTurn()
   {
      if(whoseTurn == true)
      {  
         System.out.println(firstPlayer + " it is your turn.");
      }
      else
      {
         System.out.println(secondPlayer + " it is your turn.");
      }
   }
   public static void main(String[] args)
   {
      //Create a PlayGame object
      PlayGame game = new PlayGame();

      //Plays game
      game.play();   
   }
}  

public class Game
{
   //Variables
   private int numPiles;   //number of coin piles
   private int [] coins;   //coins in each pile
   private int max = 10;
   private int min = 1;

   public void Game()
   {
      //Set random number of piles
      public int getPile(int min, int max)
      {
         Random rand = new Random();
         numPiles = rand.nextInt((max - min) + 1) + min;
         return numPiles;
      }
   }

   public void Game(int numPiles, int numCoins)
   {

   }

}
