Java write excel operation source code sharing

These two days, I helped the teacher to build a database and import the data of all experimental transactions into the database, but I didn't want to stay in the laboratory every day. The atmosphere was too depressed. I wanted to read the data into excel first and take it to the laboratory one day

The original data is like this. Different experiments have a special folder. Under the folder of experiment name, there are folders of different classes. Under the class folder, there is the class date folder. The data excel of the class doing experiments at different times is stored. There is no class and time in the original Excel. Now it is necessary to read the excel name and class name to take the information as a column, Add to excel.

The following is the source code, hey hey, by the way, I also made a visual window.
