  • 使用Eclipse在Excel中找出两张表中相同证件号而姓名或工号却出现不同的的项

    1:首先把Excel中的文本复制到txt中,复制如下:

    A表:

    证件号                           工号  姓名

    310110xxxx220130004 101 傅家宜
    310110xxxx220130005 102 顾音琪
    310110xxxx220130006 103 郭加峤
    310110xxxx220130007 104 胡奕蕾
    310110xxxx220130010 105 凌家蔚
    310110xxxx220130011 106 卢彦菁

    B表:

    证件号                           工号  姓名

    310110xxxx220130004 111 傅家宜
    310110xxxx220130005 102 顾音琪
    310110xxxx220130006 103 郭嘉峤
    310110xxxx220130007 104 胡奕蕾
    310110xxxx220130010 105 凌家蔚
    310110xxxx220130012 107 潘家莹

    2:代码和运行结果如下:
