public class ExcelWriterExample { public static void main(String[] args) throws Exception {用这个方法再写一个上面这个程序

当然可以。在这个`ExcelWriterExample`的基础上，我们继续创建一个类似的程序，这次将写入数据到Excel文件中。假设我们已经有了处理Excel数据的库，比如Apache POI。这是一个简单的例子：

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

public class ExcelWritingExample {

    // 假设你有一个包含员工信息的数据列表
    private static List<Employee> employeeData = ...; // 员工类需包含姓名、职位等属性

    public static void writeToExcel(String filePath) throws IOException {
        Workbook workbook = new XSSFWorkbook(); // 创建一个新的工作簿
        Sheet sheet = workbook.createSheet("Employee Data"); // 创建新的工作表

        // 获取第一行标题行的Row
        Row headerRow = sheet.createRow(0);
        Cell.cellType.createCell(headerRow.createCell(0), "Name");
        Cell.cellType.createCell(headerRow.createCell(1), "Position");

        // 遍历员工数据并写入Excel
        for (int i = 0; i < employeeData.size(); i++) {
            Employee employee = employeeData.get(i);
            Row dataRow = sheet.createRow(i + 1); // 行索引从1开始
            Cell nameCell = dataRow.createCell(0);
            nameCell.setCellValue(employee.getName());
            Cell positionCell = dataRow.createCell(1);
            positionCell.setCellValue(employee.getPosition());
        }

        try (OutputStream outputStream = new FileOutputStream(filePath)) {
            workbook.write(outputStream);
            System.out.println("Data has been written to the Excel file at " + filePath);
        } finally {
            workbook.close(); // 关闭工作簿
        }
    }

    public static void main(String[] args) {
        String fileName = "employees.xlsx"; // Excel文件名
        writeToExcel(fileName);
        
        //
