如果条件不匹配，如何制作计数器并重置

Question

我正在编写一个代码，我必须比较excel行之间的数据，如果我找到匹配项，我想将finalIndex增加1，一旦找到匹配项，我需要合并单元格。 在这里，我无法理解如何保持起始行号的跟踪。

以下是我的代码。请让我知道我该怎么做。

HSSFWorkbook workbook = new HSSFWorkbook(fin);
HSSFSheet sheet = workbook.getSheetAt(0);
int row = sheet.getPhysicalNumberOfRows();
String currentLawName, currentCountry, currentAssociate, previousLawName, previousCountry, previousAssociate;
String currentPages, previousPages;
int startIndex = 0, finalIndex = 0, tempNum = 0;
System.out.println(row);
for (int i = 2; i < row; i++) {
    currentAssociate = sheet.getRow(i).getCell(1).toString();
    currentLawName = sheet.getRow(i).getCell(3).toString();
    currentCountry = sheet.getRow(i).getCell(4).toString();
    currentPages = sheet.getRow(i).getCell(5).toString();

    previousAssociate = sheet.getRow(i - 1).getCell(1).toString();
    previousLawName = sheet.getRow(i - 1).getCell(3).toString();
    previousCountry = sheet.getRow(i - 1).getCell(4).toString();
    previousPages = sheet.getRow(i - 1).getCell(5).toString();

    if (currentAssociate.equals(previousAssociate) && currentCountry.equals(previousCountry)
        && currentLawName.equals(previousLawName) && currentPages.equals(previousPages)) {
        finalIndex += 1;
    } else {
        finalIndex = 0;
    }

}
System.out.println(finalIndex + "\t" + tempNum);
