Question

How do I check if a CELL in excel sheet is empty and doesn’t have any content inside it? I am traversing a row from left to right, and want to stop when I encounter an empty cell. I am using

 cell.getType()==CellType.EMPTY

but it doesn’t seem to work. Also,

if(cell.getContents() == "") is also not working.

What is the condition to check if the cell is a blank cell?

Thanks

    List cellDataList = new ArrayList();
XSSFWorkbook workbook = new XSSFWorkbook(fileInputStream);

                        XSSFSheet sheet = workbook.getSheetAt(0);

                        Iterator rows = sheet.rowIterator();

                        int number=sheet.getLastRowNum();


                        int lineNumber = 0;

                        while (rows.hasNext())

                        {
                            XSSFRow row = ((XSSFRow) rows.next());
                            lineNumber++;
                            if(lineNumber==1){continue;}




                            Iterator cells = row.cellIterator();
                            List cellTempList = new ArrayList();    
                            int current = 0, next =1;
                            while(cells.hasNext())

                            {

                                XSSFCell cell = (XSSFCell) cells.next();


                                current = cell.getColumnIndex();


                                if(current<next){

                                }

                                    int loop = current-next;

                                    for(int k=0;k<loop+1;k++){

                                        cellTempList.add(null);
