System.out.println("Data from xls is : "+ data0);

**************************************************************** Exception in thread "main" org.apache.poi.openxml4j.exceptions.OLE2NotOfficeXmlFileException: The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF) at org.apache.poi.openxml4j.opc.internal.ZipHelper.verifyZipHeader(ZipHelper.java:172)

Answer 1

 xls - HSSFworkbook
 xlsx - XSSFworkbook

Yes. For .xls you will have to use different class files.
