Part (a)

Write the constructor that initializes the game board.

Solution

public TokenPass(int numPlayers)
{
    board = new int[numPlayers];
    for (int i = 0; i < board.length; i++)
    {
        board[i] = (int)(Math.random() * 10) + 1;
    }
    currentPlayer = (int)(Math.random() * numPlayers);
}

Part (b)

Write the distributeCurrentPlayerTokens method.

Solution

public void distributeCurrentPlayerTokens()
{
    int tokens = board[currentPlayer];
    board[currentPlayer] = 0;
    int pos = currentPlayer;
    
    for (int i = 0; i < tokens; i++)
    {
        pos = (pos + 1) % board.length;
        board[pos]++;
    }
}
