RowIterator in POI

Question

Hello Techies,
Iam using jakarta's poi for reading excel sheet. Iam getting problem in using rowIterator().
int tempEno = 0;
String tempEname = null;
while (it.hasNext())
    row = (HSSFRow) it.next();
  HSSFCell cell = row .getCell(myTradingConstants.ENO_COLUMN_NUMBER);
  tempEno =(int)cell.getNumericCellValue();
  System.out.println("tempEno"+tempEno);
  cell = row.getCell(myTradingConstants.ENAME_COLUMN_NUMBER);
  tempEname = cell.getStringCellValue();
  System.out.println("tempEname"+tempEname);
}Iam getting the following exception
Exception in thread "main" java.lang.NumberFormatException: You cannot get a numeric value from a String based cell
     at org.apache.poi.hssf.usermodel.HSSFCell.getNumericCellValue(HSSFCell.java:712)
     at myTradeSample.main(myTradeSample.java:67)
cell type is either Numeric,string,error and fourmula and blank. But iam having other types also Date,Double,Time etc. In this case How to resolve the problem.
Where as if i did not used rowIterator() n by using getLastRowNum()
it is working fine.
int lastRowNumber = sheet.getLastRowNum();
for (int i = 1; i <= lastRowNumber; i++) {
HSSFCell cell = row                         .getCell(myTradingConstants.ENO_COLUMN_NUMBER);
tempEno = (int) cell.getNumericCellValue();
cell = row.getCell(myTradingConstants.ENAME_COLUMN_NUMBER);
tempEname = cell.getStringCellValue();But problem with getLastRowNum() is that iam not getting xact number of rows in the sheet.
Iam having 24 rows But it is showing 35.
Why iam facing problem with getLastRowNUmber().
thanx(inadvance),

Answer 1

But problem with getLastRowNum() is that iam not
not getting xact number of rows in the sheet.
Iam having 24 rows But it is showing 35.
Why iam facing problem with getLastRowNUmber().I don't know what this "rowiterator" is, I can't easily find it in the POI documentation. You didn't say what class it is so you can look it up yourself. However in regard to your last question: there's a method in HSSFSheet whose description says
"Returns the number of phsyically defined rows (NOT the number of rows in the sheet)"
This suggests that you don't understand the various kinds of rows, physically-defined or not.
