but i dont have a close method to c

Answer 1

Workbook.close() was implemented in poi 3.11 version.

You have to close your output stream after work with workbook is done and it was written.

From POI user guide:

Workbook wb = new XSSFWorkbook();
FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");
wb.write(fileOut);
fileOut.close();

Don't forget to close workbook as well:

wb.close();

Answer 2

cant find close() method on Apache WorkbookFactory

You need to close the Workbook, not its factory.

Note 1: that in order to properly release resources the Workbook should be closed after use.

Correct.

Note 2: also that loading from an InputStream requires more memory than loading from a File

Untrue, unless the InputStream is a ByteArrayInputStream.
