如何使用 apache POI 根据 excel 中的多列值查找数据

Question

I am using the apache poi for reading and writing values to excel file with java. I have below excel file, from that file i need to fetch data which comes under my required criteria.

Application	CaseID	FeeType	Comments
AppA	1234	Security	Add Comments
AppB	1235	Other	Case created
AppA	1236	Security	Added Comments

In my code I want to get all the cases which comes under below criteria, Application set to "AppA",Fee Type set to "Security" and Comments with "Add Comments".

I used below code to filter using two columns for search criteria, but i cannot add the third criteria. Please help me.

ArrayList<Object> ApplicationCases = new ArrayList<Object>();

    for (Row row : sheetName) {
        for (Cell cell : row) {
            if (cell.getCellType() == CellType.STRING) {
                if (cell.getRichStringCellValue().getString().trim().equals(requiredCellContent1)) {
                    int rowNumber = row.getRowNum();

                    XSSFRow row1 = sheetName.getRow(rowNumber);
                    XSSFCell selectedCellValue = null;

                    short cellcount = row1.getLastCellNum();

                    for (int i = 0; i < cellcount; i++) {

                        if (row1.getCell(i).getRichStringCellValue().getString().trim()
                                .equals(requiredCellContent2)) {
                            selectedCellValue = row1.getCell(1);
                            ApplicationCases.add(selectedCellValue);

                        } else if (selectedCellValue == null || row1.getCell(i).getCellType() == CellType.BLANK) {
                        }
                    }
}
}

Can you so something like below

Iterator<Row> rows = sheet.rowIterator();
while(rows.hasNext()) {
    Row row = rows.next();
    String app = row.getCell(0).getRichStringCellValue().getString();
    String feeType = row.getCell(2).getRichStringCellValue().getString();
    String comment = row.getCell(3).getRichStringCellValue().getString();
    
    if(app.equals("AppA") && feeType.equals("Security") && comment.equals("Add Comments")) {
        //Here is your condition satisfied
    }
}
