Java 如何在excel中逐行打印传递的字符串

我正在excel中打印一些字符串值

在excel中，当前正在打印最后一个字符串，但我需要逐行打印它们

代码

    public void demoKey(String name) throws IOException{

        FileInputStream fis = new FileInputStream("C:\\Users\\lahiruh\\Katalon Studio\\Project Decypha\\Decypha data files\\Demo1.xlsx");
        XSSFWorkbook workbook = new XSSFWorkbook(fis);

        XSSFSheet sheet = workbook.getSheet("Sheet1");
        int rowCount = sheet.getLastRowNum()-sheet.getFirstRowNum();
        Row row = sheet.createRow(rowCount+);
        Cell cell = row.createCell(0);
        cell.setCellType(cell.CELL_TYPE_STRING);
        cell.setCellValue(name);
        FileOutputStream fos = new FileOutputStream("C:\\Users\\lahiruh\\Katalon Studio\\Project Decypha\\Decypha data files\\Demo1.xlsx");
        workbook.write(fos);
        fos.close();

现在我可以得到如下输出（覆盖每个值并给出最后一个字符串）

我想知道你必须按照以下方式来做

首先创建一组行

创建单元格并定义单元格数据类型

将值存储在单元格中

我在下面提供了逐行存储数据的结构

int rowNumber = 0; // Row number starting with 0

for (i = 0 ; i < 10 ; i++) { //This for loop can be your data set

    Row row = sheet.createRow(rowNumber++);

    int columnNumber = 0; //Cell or Column number starting with 0
    for (j = 0 ; j < 5 ; j++) { //This for loop can be your data set
       Cell cell = row.createCell(columnNumber++);
       cell.setCellValue("Some string value");
    }
}

int rowNumber=0；//以0开头的行号
for（i=0；i<10；i++）{//这个for循环可以是您的数据集
Row Row=sheet.createRow（rowNumber++）；
int columnNumber=0；//单元格或列编号以0开头
for（j=0；j<5；j++）{//这个for循环可以是您的数据集
Cell Cell=row.createCell（columnNumber++）；
setCellValue（“某些字符串值”）；
}
}

试试这个

for(int i = 0; i < arrOfStr.size(); i++)
{
    String a = arrOfStr[i];
    System.out.println(a);
    //CustomKeywords.'WriteExcel.demoKey'(a)
    CustomKeywords.'WriteExcel.demoKey'(a,i)
}

这里的问题是什么？我需要一行一行地打印值，目前，它在同一行打印并相互覆盖

for(int i = 0; i < arrOfStr.size(); i++)
{
    String a = arrOfStr[i];
    System.out.println(a);
    //CustomKeywords.'WriteExcel.demoKey'(a)
    CustomKeywords.'WriteExcel.demoKey'(a,i)
}

public void demoKey(String name, int index) throws IOException{

        FileInputStream fis = new FileInputStream("path");
        XSSFWorkbook workbook = new XSSFWorkbook(fis);

        XSSFSheet sheet = workbook.getSheet("Sheet1");
        Row row = sheet.createRow(index + 1);
        Cell cell = row.createCell(0);
        cell.setCellType(cell.CELL_TYPE_STRING);
        cell.setCellValue(name);
        FileOutputStream fos = new FileOutputStream("path");
        workbook.write(fos);
        fos.close();
    }
}
