I am not able to extract the checkboxes from the tabular cells and also another table. at present I am using Apache poi, I need your suggestion and help to parse the data from a word document, in the next step I am going to compare this tabular data with another word document

Update a list inside iterator loop

This code tries to iterate over an excel file and load the data to a List<List<String>> but it throws java.lang.NullPointerException at resultList.add(rrow) but it is not clear what is the problem with it:

Your resultList was never created (it's null). You can fix it by defining it as follows:
public List<List<String>> resultList = new ArrayList<>();

Searching Specific Excel Cell using Java Apache POI

I am using Apache POI API to read Excel file and check the quantity of products available or not. I am successfully reading excel file using below code but I am unable to read the specific cell (Quantity Column) to check weather asked product is available or not

}
this is my excel file

using opencsv 4.1 i do this
import org.apache.commons.lang.StringUtils;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
...
try (InputStream excelFile = new FileInputStream(new File(fileName));
Workbook wb = new XSSFWorkbook(excelFile);) {
for (int numSheet = 0; numSheet < wb.getNumberOfSheets(); numSheet++) {
Sheet xssfSheet = wb.getSheetAt(numSheet);
xssfSheet.forEach(row -> {
Cell cell = row.getCell(0);
if (cell != null) {
if(StringUtils.isNumeric(cell.getStringCellValue())){
// Use here cell.getStringCellValue()
}
}
});
}
}

Use below for loop:
for(int r=sh.getFirstRowNum()+1; r<=sh.getLastRowNum(); r++){ //iterating through all the rows of excel
Row currentRow = sh.getRow(r); //get r'th row
Cell quantityCell = currentRow.getCell(4); //assuming your quantity cell will always be at position 4; if that is not the case check for the header value first
String currentCellValue = quantityCell.getStringCellValue();
if(currentCellValue.equalsIgnoreCase(<value you want to campare with>))
//<do your further actions here>
else
//do your further actions here
}

I am getting an error message saying that the static field "CELL_TYPE_***" should be accessed in a static way

I am getting an error message when I hover over the 'CELL_TYPE_****' methods in the method getCellData(), saying that 'the static field "CELL_TYPE_***" should be accessed in a static way' and a strike line over them.

In instructions such as :
else if(Cell.getCellType()==Cell.CELL_TYPE_STRING)
despite appearances, Cell is an instance and not a class as you declare this field in your class:
XSSFCell Cell = null;
But static fields and methods have no need to be prefixed by an instance to call them but by the class.
So you should prefix the static fields you are referencing like that :
else if(Cell.getCellType()==XSSFCell.CELL_TYPE_STRING)
To avoid this kind of misleading code that gives the impression that you are using as prefix an instance while you are using actually a class, follow the Java code conventions that say among other things that variable names should start by a lowercase character.
This is better :
XSSFCell cell = null;
...
else if(cell.getCellType() == XSSFCell.CELL_TYPE_STRING)
As a side note, the CELL_TYPE_STRING static field is deprecated since POI 3.15 beta 3.
You are advised to use the enum org.apache.poi.ss.usermodel.CellType.STRING instead of.

Well, first of all you should rename your variables, so that they start with lower-case letters (e.g. cell instead of Cell) to avoid confusion.
So cell is an instance of class XSSFCell which inherits from Cell.
The static fields e.g. CELL_TYPE_STRING are declared in the class Cell
: so you should use Cell.CELL_TYPE_STRING instead of cell.CELL_TYPE_STRING

Reading Excel checkbox values in Java Apache POI

I have spent countless hours trying to find a solution to this. I have tried Apache POI, JExcel and JXLS but no where have I found code to successfully read checkbox (form control) values.
If anyone has found a working solution then it would be great if you could share it here. Thanks!
UPDATE
I have written code that reads the checkbox but it cannot determine whether it is checked or not.

Sorry for the late reply, but I ran into the same. I found a trick to determine the checkbox state.
In your example you ar looping over the SubRecords and you examine the CommonObjectDataSubRecord. But the value for the checkbox can be found in the one of the SubRecord.UnknownSubRecord. This is unfortunately a private class so you cannot call any method on it, but the toString() reveals the data, and with a little regex the value can be found. So using the code below I managed to retrieve the state of the checkbox:
Pattern p = Pattern.compile("\\[sid=0x000A.+?\\[0(\\d),");
if (!(subRecord instanceof CommonObjectDataSubRecord)) {
Matcher m = p.matcher(subRecord.toString());
if (m.find()) {
String checkBit = m.group(1);
if (checkBit.length() == 1) {
boolean checked = "1".equals(checkBit);
checkBox.setChecked(checked);
}
}
}
Now my challenge is to retrieve the checkbox value in a xlsx file...
