java - 使用 selenium webdriver 在第 2 列中写入数据时，数据从第 1 列中删除

Question

这是我的代码:

    public static String[] array1 = {"devu","xyz","test","bb","run"};
    public static String[] array2 = {"dvu","yz","tet","b","run"};


 String excelFileName = "C:/Users/admin/IdeaProjects/Google_Demo/Write1.xlsx";//name of excel file

        String sheetName = "Sheet1";//name of sheet

        XSSFWorkbook wb = new XSSFWorkbook();
        XSSFSheet sheet = wb.createSheet(sheetName);

        //iterating r number of rows
        for (int r = 0; r < 5; r++) {
            XSSFRow row = sheet.createRow(r);

            //iterating c number of columns
            for (int c = 0; c < 1; c++) {
                if (!row.equals(null)) {
                XSSFCell cell = row.createCell(c);

                cell.setCellValue(array1[r]);

            }
        }}



        int count1 = 0;
        for (int r = 0; r < 5; r++) {
            XSSFRow row1 = sheet.createRow(r);


            //iterating c number of columns
            for (int c = 2; c < 3; c++) {

                if (row1.equals(null)) {
                    row1 = sheet.createRow(count1);
                }
                    XSSFCell cell = row1.createCell(c);


                    cell.setCellValue(array2[r]);
                    count1++;

                }


            }

            FileOutputStream fileOut1 = new FileOutputStream(excelFileName);

            //write this workbook to an Outputstream.
            wb.write(fileOut1);
            //fileOut.flush();
            fileOut1.close();
        }

我使用了 2 个数组并使用 Selenium webdriver 和 POI 将数据写入 excel。

它工作正常如果我只写入第一个数组的数据但是一旦第二个数组的循环运行，它就会从 excel 的第一列中删除数据并在新列中只写入第二个数组的数据。

Answer 1

这是因为您在第二个 for 循环 中再次创建了一个新的 row。应删除下面的行以使您的代码按照规定的行为工作 -

XSSFRow row1 = sheet.createRow(r);

下面是完整的更新代码-

public static String[] array1 = {"devu","xyz","test","bb","run"};
public static String[] array2 = {"dvu","yz","tet","b","run"};
String excelFileName = "C:/Users/admin/IdeaProjects/Google_Demo/Write1.xlsx";//name of excel file

String sheetName = "Sheet1";//name of sheet

XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet(sheetName);
//iterating r number of rows
for (int r = 0; r < 5; r++) {
    XSSFRow row = sheet.createRow(r);
    //iterating c number of columns
    for (int c = 0; c < 1; c++) {
            XSSFCell cell = row.createCell(c);
            cell.setCellValue(array1[r]);

    }
}
for (int r = 0; r < 5; r++) {
    XSSFRow row = sheet.getRow(r);
    // As per current input and code, this if block will never execute. 
    // However, adding it so that later, if first for loop will change, this code can work.
    if(row == null){
        row = sheet.createRow(r);        
    } 
    //iterating c number of columns
    for (int c = 2; c < 3; c++) {
        XSSFCell cell = row1.createCell(c);
        cell.setCellValue(array2[r]);
    }
}

FileOutputStream fileOut1 = new FileOutputStream(excelFileName);
//write this workbook to an Outputstream.
wb.write(fileOut1);
//fileOut.flush();
fileOut1.close();
