           for(XSLFSlide srcSlide : src.getSlides()){
              //merging the contents
              ppt.createSlide().importContent(srcSlide);
           }
        } 
        String file3 = "C:/poippt/combinedpresentation.pptx";
        //creating the file object
        FileOutputStream out = new FileOutputStream(file3);
        // saving the changes to a file
        ppt.write(out);
        System.out.println("Merging done successfully");
