如何制作一个加载骰子

Question

我正在创建一个名为Loaded Dice的Dice类的子类，它将使骰子滚动加载并按一定百分比，看起来有点像;

public LoadedDice (int anumSides,int loadVal, double loadPct)

但是我不知道从哪里开始，我已经有了一些想法来创建一个ArrayList并让它拥有更多的一个数字，然后其他人从那里随机挑选但是那里＆＃ 39;那必须是一个更干净的方式来做那么对吗？

public class Dice
{

    // --------------------------------------------
    // Instance Variables
    // --------------------------------------------
    private ArrayList<Die>  dieArray;

    // ------------------------------------------------
    // Constructors
    // -----------------------------------------------
    /**
     * Default Constructor creates 2 6 sided dice
     */
    public Dice ()
    {
        dieArray = new ArrayList<Die>();
        dieArray.add(new Die());
        dieArray.add(new Die());
    }

    /**
     * Takes an ArrayList of die objects to use
     */
    public Dice (ArrayList<Die> someDice)
    {
        dieArray.addAll(someDice);
    }

    /**
     * Takes in 1 int (# of dice), which creates that number of 6-sided
     * dice
     */
    public Dice (int numberOfDice)
    {
        dieArray = new ArrayList<Die>();
        for (int i = 0; i < numberOfDice; i++)
        {
            dieArray.add(new Die());
        }
    }

    /**
     * Takes in 2 ints (# of dice, # of sides per die) which creates that
     * number of dice with that number of sides per die
     */
    public Dice (int numberOfDice, int numberOfSides)
    {
        dieArray = new ArrayList<Die>();
        for (int i = 0; i < numberOfDice; i++)
        {
            dieArray.add(new Die(numberOfSides));
        }
    }

    // -------------------------------------------------
    // Class Methods
    // -------------------------------------------------
    /**
     * ContainsDice: takes 0 parameters, and returns a string value
     * representing all of the dice
     */
    public String ContainsDice ()
    {
        String dieString = new String();
        for (int i = 0; i < dieArray.size(); i++)
        {

            dieString += (dieArray.get(i) + " ");
        }
        return dieString;
    }

    /**
     * Roll: takes 0 parameters, and returns an int value that is the sum
     * of all the dice rolled
     */
    public int Roll ()
    {
        int value = 0;

        for (int i = 0; i < dieArray.size(); i++)
        {
            value = value + dieArray.get(i).roll();
        }

        return value;
    }

    /**
     * Add: Takes a Die object as an input parameter and adds it to the
     * current Dice
     */
    public void Add (Die newDie)
    {
        dieArray.add(newDie);
    }
}

此外，所有Dice类都来自我创建的模具类。如果需要，我也可以提供。
