How can you get the number of sheets in a workbook in Java?

To obtain the number of sheets in a workbook, you can use the getNumberOfSheets() method in the Workbook class. An example is shown below:

Workbook workbook = new XSSFWorkbook(new FileInputStream("workbook.xlsx"));
int numberOfSheets = workbook.getNumberOfSheets();
System.out.println("Number of sheets in the workbook: " + numberOfSheets);

The code above will print the number of sheets in the workbook.
