2.Java Beans To Excel:

-Converts Java Beans to Excel files (xlxs) via Apache POI including cellformats.

-BeanColumn:This class represents a column in the Excel sheet. It defines properties.

-FormatType:represents different data formats that a column in the Excel sheet.

-bean2xlsx(List<?> data, BeanColumn[] columns, String filename, String sheetname):

Converts the list of beans to an Excel file.

It calls addSheet() to add data to the workbook, then writes the workbook to the specified file.

-We Run Junit test cases for this project are:

which is responsible for exporting data to an Excel file.

exportDataToXlxs() Test Case:verify whether the Bean2xlsx class correctly exports data to

an Excel file when provided with a small amount of test data.

createBigXLSx() Test Case: This test case verifies the behavior of the Bean2xlsx class

when dealing with a large amount of data.

I write my own test cases are:

exportEmptyDataToXlsx() and it checks the behavior of the Bean2xlsx class

when provided with an empty data list.
