1、问题

感觉应该能移除相同的元素呀,好像貌似没有移除

    @Override
    public boolean retainAll(Collection<?> c) {
        if(c instanceof Bag) {
            Bag other = (Bag)c;
            Object[] otherElements = other.elements;
            for(int i=0;i<other.counter;i++) {
                if((contains(otherElements[i]))==true) {
                    this.remove( i );
                    }
                }
            }
        
        return false;
    }

2、吐槽

秋天都过去好长时间了,还这么热
