// I found no example anywhere of how to build and edit a new Google Slides presentation via the Java API client.
// So here you go: how to create two empty slides.

        Presentation prezTemp = new Presentation();

        prezTemp.setTitle("test_" + String.valueOf(Math.random()));

        prez = googleSlides.presentations().create(prezTemp).execute();
        
        BatchUpdatePresentationRequest update = new BatchUpdatePresentationRequest(); 
        Request request = new Request();
        Request request1 = new Request();
        CreateSlideRequest slide = new CreateSlideRequest();
        request.setCreateSlide(slide);
        request1.setCreateSlide(slide);
        
        List<Request> requests = new ArrayList();
        requests.add(request);
        requests.add(request1);
        update.setRequests(requests);
        googleSlides.presentations().batchUpdate(prez.getPresentationId(), update).execute();
