使用Java创建excel

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

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

public class CreateExcelExample {
    public static void main(String[] args) {
        // 创建工作簿
        Workbook workbook = new XSSFWorkbook();

        // 创建工作表
        Sheet sheet = workbook.createSheet("Sheet1");

        // 创建行
        Row row = sheet.createRow(0);

        // 创建单元格
        Cell cell = row.createCell(0);
        cell.setCellValue("Hello");

        // 保存Excel文件
        try (FileOutputStream outputStream = new FileOutputStream("example.xlsx")) {
            workbook.write(outputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }

        System.out.println("Excel文件创建成功！");
    }
}
