Question

I am using following POI api to write on excel through java code

public static HSSFWorkbook sampleWorkbook = new HSSFWorkbook();
public static HSSFSheet sampleDataSheet = sampleWorkbook.createSheet("ABC");

It is creating a sheet in excel with name of ABC. That is ok
My Question is I need to add/create another sheet with name of “XYZ” in same workbook. How do I do that? As if I write something like this

public static HSSFSheet sampleDataSheet = sampleWorkbook.createSheet("XYZ");

it would override the first one(ABC)..

Answer 1

It will not override the first one, it will create a new sheet, but you need to assign it to a different variable:

HSSFSheet firstSheet = sampleWorkbook.createSheet("ABC");
HSSFSheet secondSheet = sampleWorkbook.createSheet("XYZ");

Here’s the documentation:

public XSSFSheet createSheet(java.lang.String sheetname)

Create a new sheet for this Workbook and return the high level
representation. Use this to create new sheets.
