How to get row count in an Excel file using POI library?

Question

Guys I\'m currently using the POI 3.9 library to work with excel files. I know of the getLastRowNum() function, which returns a number of rows in an Excel file.

Answer 1

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)

2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'
