如何检查Apache POI中数字单元格的空白？

Question

All is in the title.

How can I check if a CELL_TYPE_NUMERIC is empty with POI ? With strings i can use the isEmpty() method but with int I have no ideas (null is not allowed and zero just wont do it).

Thank you in advance.

Answer 1

Empty cells should not have format in POI since there is already a type for empty cells.

To check if the cell is empty you should test if the cell type is Cell.CELL_TYPE_BLANK . Sometimes empty cells do not exist in a Row ; they will be null in this case.

Answer 2

You can check the raw value of the cell

public BigDecimal determinePorpertyValue(XSSFCell cell) {
    String rawValue = cell.getRawValue();
    return rawValue == null ? null : BigDecimal.valueOf(cell.getNumericCellValue());
}
