[simple_lly]

public static void main(String[] args) {
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet spreadsheet = workbook.createSheet("formula");
XSSFRow row = spreadsheet.createRow(1);
XSSFCell cell = row.createCell(1);

cell = row.createCell(2);
// Create MAX formula
cell.setCellType(XSSFCell.CELL_TYPE_FORMULA);
cell.setCellFormula("IFERROR(ROUND(Q4/P4,2),0)");
System.out.println("---------");

}
