问题描述:
abc表示该行描述的是一个产品,10/11代表产品编号,2表示产品数量
aa表示该行是对产品的描述信息(产品良好或不良),10/11来自abc编号,1表示产品数量
产品实体类product,有如下字段:
id,name,count(数量),remarks,goodproductNo(良品数量),badproductNo(次品数量)
问题是:如何用程序来分别统计编号为10,11的产品到底有多少良品,多少不良品,然后赋
值给实体类product,
* aaa.txt *
abc|10|测a试1|2|备注|
abc|11|测a试2|3|备注|
aa|10|1|良好商品·|
aa|10|1|良好商品·|
aa|11|1|不良商品·|
aa|11|1|良好商品·|
aa|11|1|良好商品·|

输出:
