博客指出运行中存在的Bug，选择JCheckBox 1或JCheckBox 6后无法自行取消选择，且二者相互关联，选择其一同时会取消另一选择，其他按钮正常。

运行结果：
在这里插入图片描述
Bug：选择JCheckBox 1不能再点击它取消选择，选择 JCheckBox 6 不能再点击它取消选择。只要点击过JCheckBox 1 或者 JCheckBox 6，然后，不能JCheckBox 1 和 JCheckBox 6 都不能通过自己取消选择，但，JCheckBox 1 和 JCheckBox 6 竟相互关联了：选择JCheckBox 1的同时会取消 JCheckBox 6 ，反正亦然，除此之外其他按钮都正常。
