I use the following approach to read data from excel (csv) sheet:
InputStream inputStream = new BufferedInputStream(multipartFile.getInputStream());
XSSFWorkbook myWorkBook = new XSSFWorkbook(inputStream);
List<String> cellList = new ArrayList<>();
XSSFSheet mySheet = myWorkBook.getSheetAt(0);
Iterator<Row> rowIterator = mySheet.iterator();
rowIterator.next();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
cellList.clear();
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) { // this returns false even the cell has data
Cell cell = cellIterator.next();
cellList.add(cell.getStringCellValue());
}
}
I want to make cellIterator.hasNext()
returns true for empty cell values as in the second row (name). So, how can I do that?

CodePudding user response:
You can't make cellIterator.hasNext()
return true for the empty "name" cell.
If you know in advance the number of column in advance, you can use a loop and row.getCell(index)
.
for (int i = 0; i < 3; i ) {
Cell cell = row.getCell(i);
cellList.add(cell == null ? "Empty":cell.toString());
}
If you don't, you have to scan first of your file to count the number of columns.
