Java 如何通过selenium在excel中编写数组对象内容 int col=driver.findElements（By.xpath（“//table[@id=\“transactionListData\”]/thead/tr/th”）.size（）； int row=driver.findElements（By.xpath（“//table[@id=\“transactionListData\”]/tbody/tr”）.size（）； //ArrayList mydata=新的ArrayList（）； Object[]ob=新对象[行][col]； 对于（int i=1；i

上述问题的答案是：

public static String writeIntoExcel(Object ob, int rowi,int colj ) throws IOException
{
    int rowcount =  rowi;
    int colcount = colj;
    Object oa[][]  = new Object[rowcount][colcount];
    oa =  (Object[][]) ob;
    XSSFWorkbook workbook = new XSSFWorkbook();
    XSSFSheet sheet = workbook.createSheet("Transacton History");

    for (int i=1; i<=rowcount ; i++)
    {
        for (int j=1; j<=colcount ; j++)
        {
            String val = (String) oa[i][j];
            Row row = sheet.createRow(i);
            row.createCell(colj).setCellValue(val);
        }
    }
    FileOutputStream fileOut = new FileOutputStream("\"\\\\btfin.com\\filesrv\\User\\Offshore\\SG1\\L097117\\user\\My Documents\\workbook.xlsx");
    workbook.write(fileOut);
    fileOut.close();

    return "Data is written";
}

Object[][]ob=新对象[行][col]；
对于（int i=1；i您得到的错误是什么？将该信息和任何其他相关信息添加到您的问题中。您应该花一些时间阅读有关此问题的教程。您这样做的方式效率不高且令人困惑。为什么要传递
对象而不是字符串数组之类的特定数据类型？如果传入arr是的，您不需要传入行和列，因为您可以从数组维度本身获取。不要返回“数据已写入”之类的内容，而是返回布尔值…
true
（如果成功），或
false
（如果未成功）或类似的内容。
