您需要修改代码逻辑,如下所示。因为,某些单元格具有空白值,因此抛出空指针异常。我们需要处理NULL Cell Value,如下所示
修改了For循环代码:
//Column Index
int column=0;
for(int i=1; i<rowcount;i++){
Row r=sheet.getRow(i);
Cell c=r.getCell(column, Row.RETURN_BLANK_AS_NULL);
if(c==null){
questionType="";
}
else{
questionType=r.getCell(column).getStringCellValue();
}
System.out.println(questionType);
}
