如何使用java读取excelsheet中的列？

如何解决如何使用java读取excelsheet中的列？

我有一个 excelsheet，其中有类似这样的数据，我的要求是读取 excelsheet 并获取类型为 dropdown 的 screen_name，这是我的示例输入，我还添加了可用作参考的输出

Seq     Screen_name        Type     
1.0     ds_top             dropdown     
2.0     ds_level            detail  

输出将是：- ds_top

我能够读取 excelfile 并获取 screen_names 和类型的列值，但如何实现进一步的逻辑

感谢任何帮助
