SE - 71 - Interface and its implementations in excel

We have 3 flavours of classes used in excel:

HSSF : To handle .xls type of excel(older versions of excel)

SXSSF : It is an API-compatible streaming extension of XSSF to be used when very large spreadsheets have to be produced, and heap space is limited

XSSF : To handle .xlsx type of excel(newer versions of excel)
