}
}
上面的类运行的结果你会猜到么?
<?xml version="1.0" encoding="UTF-8"?><Price><PsgType>ADT</PsgType></Price>
乘客类型:ADT
<?xml version="1.0" encoding="UTF-8"?><Price><PsgType>CHD</PsgType></Price>
乘客类型:ADT
就这个结果让我想了好久,也曾试着跟进去看看代码的实现,不过恕我本人愚笨,未曾找到,
但就此结果让我甚是想不通。纠结了很久。如果你也想知道答案的话,下篇文章会有答案的,
不过还是希望看到的人能独立思考下。大家可以交流下心得
