Apache POI, using both XSSF and HSSF

Question

I have a problem with Apache POI project.

I failed to use XSSF and HSSF in the \"Same Java Class\". Which jar should I dow

Answer 1

Use the factory instead which handles both xssf and hssf

import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;

Workbook wb = WorkbookFactory.create(new File("file"))
