I'm using the Apache 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.
The only problem is `getLastRowNum()` returns a number with the count starting from 0.
So, if an Excel file uses the first 3 rows, `getLastRowNum()` returns 2.
If an Excel file has just 1 row, `getLastRowNum()` returns 0.
The problem occurs when the Excel file is completely empty. `getLastRowNum()` still returns 0, so I cannot determine if the Excel file has 1 row of data, or if its empty.
How can I detect if an Excel file is empty or not?

Try [Sheet.getPhysicalNumberOfRows()](http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFSheet.html#getPhysicalNumberOfRows%28%29)
