如何使用Java SE计算Microsoft Excel文件中的工作表数？

Answer 1

Java SE中没有与MS Excel连接的标准类/库文件。在Apache POI中，您可以使用HSSFWorkbook.getNumberOfSheets()方法返回工作簿中工作表的数量。

要打开Excel文件并获取HSSFWorkbook，请执行以下操作：

String fileName = "C://Excel.xls";
POIFSFileSystem fileSystem = new POIFSFileSystem(new FileInputStream(fileName));
HSSFWorkbook workbook = new HSSFWorkbook(fileSystem);

Answer 2

在getNumberOfSheets()课程中使用WritableWorkbook。

看看这些：

jxl.Workbook;
jxl.write.Label;
jxl.write.WritableSheet;
jxl.write.WritableWorkbook;

Answer 3

使用以下代码获取工作表数量

FileInputStream file = new FileInputStream(new File(FILE PATH));            

XSSFWorkbook workbook = new XSSFWorkbook(file);         

System.out.println("number of sheet::"+ workbook.getNumberOfSheets());

Answer 4

您可以使用xlsx4j 来计算。这是我的代码：

public static void main(String[] args) throws InvalidFormatException, Docx4JException {
    SpreadsheetMLPackage spPackage = SpreadsheetMLPackage.load(new File("D:/MyFile.xlsx"));
    List<Sheet> sheetList = spPackage.getWorkbookPart().getJaxbElement().getSheets().getSheet();
    System.out.println("Number of worksheet: "+ sheetList.size());
    System.out.println("Sheet name: ");
    for (Sheet sheet : sheetList) {
        System.out.println(sheet.getName());
    }

Answer 5

public int getNumberOfSheets(File)throws Exception{
 FileInputStream fileInputStream = new FileInputStream(file);
 HSSFWorkbook workbook = new HSSFWorkbook(fileInputStream);
 int number_of_sheets =     workbook.getNumberOfSheets();
 return number_of_sheets
}

以上是获取xls工作簿中的工作表数量的简单方法
