Answer 1

Delete a sheet using Apache POI

//Open file
  FileInputStream inputStream = new FileInputStream(new File(filePath));
  XSSFWorkbook workBook = new XSSFWorkbook(inputStream);

//Delete Sheet
  workBook.removeSheetAt(resultWorkbook.getSheetIndex("SheetToBeDeleted"));

//Save the file
  FileOutputStream outFile =new FileOutputStream(new File(filePath));
  workBook.write(filePath);
  outFile.close();

Answer 2

After editing your workbook, you need to write it again. Try this:-

FileOutputStream output = new FileOutputStream(destFile);
workbook.write(output);
output.close();

Edit:- After writing it back, you can return your destFile.

Answer 3

private void removeOtherSheets(String sheetName, XSSFWorkbook book) {       
        for(int i=book.getNumberOfSheets()-1;i>=0;i--){
            XSSFSheet tmpSheet =book.getSheetAt(i);
            if(!tmpSheet.getSheetName().equals(sheetName)){
                book.removeSheetAt(i);
            }
        }       
}
