找不到符号 Workbook.close()

Question

我看到了多个关于此 header 的问题，但没有得到我的答案。

 private void createHandBackFile(XSSFSheet sheet, String programId, XSSFWorkbook workbook) throws IOException {
    String output = "C:\Users\muddassirr\Downloads\Personal\STORE\Output";

    File file = new File(output + File.separator + programId);
    if (!file.exists()) {
        file.mkdirs();
    }
    int noOfColumns = sheet.getRow(0).getPhysicalNumberOfCells();
    for(int i = 0; i < noOfColumns; i++) {
        sheet.autoSizeColumn(i);
    }
    FileOutputStream outputStream = new FileOutputStream(new File(output + File.separator + programId + File.separator + "HAND_BACK.xlsx"));
    workbook.write(outputStream);
    outputStream.close();
    workbook.close();
}

没有编译错误。但是当我运行我得到运行时间错误说

java: cannot find symbol
symbol:   method close()
location: variable workbook of type org.apache.poi.xssf.usermodel.XSSFWorkbook

Answer 1
