在Java中将文件另存为CSV (apache poi)

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

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

public class CSVConverter {
    public static void main(String[] args) {

        Workbook workbook = new XSSFWorkbook();

        // 创建Sheet对象
        Sheet sheet = workbook.createSheet("Sheet1");

        // 添加数据
        Row row1 = sheet.createRow(0);
        row1.createCell(0).setCellValue("Name");
        row1.createCell(1).setCellValue("Age");
        row1.createCell(2).setCellValue("City");

            workbook.write(fos);
        } catch (IOException e) {
