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Selenium webdriver和POI获取了2个数组并将数据写入excel。

它工作正常如果我只写第一个数组的数据但是第二个数组的循环运行后，它会从excel的第一列删除数据，只在新列中写入第二个数组的数据。

这是因为您在第二个row中再次创建新的for loop。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);

以下是完整的更新代码 -

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();

使用selenium webdriver在第2列中写入数据时，数据将从第1列中删除
