摸🐠🐴，一个模拟炉石开卡包的小东西

1. 翻出个以前的课设项目，改了改 UI，发现无论怎么改都太难看了
2. 还有一点就是按概率抽取卡牌这个有疑问,暂时的实现代码在下面，实际运行之后发现橙卡抽到的概率高于预期的 0.4%

private static final Double[] WEIGHTS = new Double[]{0.4,4.1,24.5,71.0};
    private static final Integer[] ID = new Integer[]{LEGEND,EPIC,RARE,COMMON};
    private static int randomChoice(){
        double sumOfWeight = 0;
        for (Double weight : WEIGHTS) {
            sumOfWeight += weight;
        }
        Random random = new Random();
        double randNumber = random.nextDouble()*sumOfWeight;
        for (int i = 0; i < WEIGHTS.length; i++) {
            if (randNumber<WEIGHTS[i]) return ID[i];
            randNumber -= WEIGHTS[i];
        }
        return COMMON;
    }

    public static int[] getARandomSet(){
        int[] sum = new int[5];
        for (int i = 0; i < 5; i++) {
            sum[randomChoice()]++;
        }
        return sum;
    }

ps: 卡牌图片是外站的资源，所以会有某些卡牌图片缺失
