How to find the value of the column in POI API

Java APIS

In this page of the tutorials we are going to find the value of row from the column of an excel sheet using POI2.5 API Event. The org.apache.poi.hssf.record.NumberRecord class extends Record and implements CellValueRecord interface, 
java.lang.Comparable interface.

 getRow():-
This methods get the row from cell.
getColumn():-
This methods get the column from cell defines within the row. 
getNumStrings():-
This methods fine the number of strings.
