I want to create a file .xls but when I set a value it gives me null pointer. this is my code :
(the file xls is empty at start and I need to create two sheet from the code):
Workbook wb = new HSSFWorkbook(); Sheet general=wb.createSheet("General"); //after this line it gives me null point Row row = general.getRow(0); Cell cell = row.getCell(1);
It seems that "general" is null.Anyone can help me?
getRow(0) throws Exception because row-0 does not exist.
you need to create the row in the first place :
Row row = general.createRow(0);
