如何在java中比较并获得预期的结果excel表？

import org.apache.poi.ss.usermodel.*;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class ExcelComparator {
    public static void main(String[] args) {
        String inputFile = "input.xlsx";
        String outputFile = "output.xlsx";

        try (Workbook workbook = WorkbookFactory.create(new FileInputStream(inputFile));
             Workbook outputWorkbook = WorkbookFactory.create(new FileInputStream(outputFile))) {

            Sheet sheet = workbook.getSheetAt(0);
            Sheet outputSheet = outputWorkbook.createSheet("Result");

            int rowCount = sheet.getLastRowNum();
            for (int i = 0; i <= rowCount; i++) {
                Row row = sheet.getRow(i);
                Row outputRow = outputSheet.createRow(i);

                Cell cell1 = row.getCell(0);
                Cell cell2 = row.getCell(1);

                // 比较逻辑示例：比较第一列和第二列的值
                if (cell1.getStringCellValue().equals(cell2.getStringCellValue())) {
                    // 预期结果为相等，将结果写入到新的Excel表中
                    Cell outputCell = outputRow.createCell(0);
                    outputCell.setCellValue("Equal");
                } else {
                    // 预期结果为不相等，将结果写入到新的Excel表中
                    Cell outputCell = outputRow.createCell(0);
                    outputCell.setCellValue("Not Equal");
                }
            }

            // 保存新的Excel文件
            try (FileOutputStream outputStream = new FileOutputStream(outputFile)) {
                outputWorkbook.write(outputStream);
            }

            System.out.println("Comparison completed successfully.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
