    // 资源类

    public static void main(String[] args) {
        BitSet bitset = new BitSet(66);//66 设置size 二进制的位数
        bitset.set(11, true);
        bitset.set(10, true);
        bitset.set(8, true);
        for (int i = 0; i < 16; i++) {

                System.out.println(i);
            }
        }
        System.out.println(bitset);//{8,10,11}
        System.out.println(bitset.size());//128 默认64
        System.out.println(bitset.length());//12
