import org.apache.poi.xslf.usermodel.XSLFSlide;
public class MergingMultiplePresentations {
   public static void main(String args[]) throws IOException {
      //creating empty presentation
      XMLSlideShow ppt = new XMLSlideShow();
      //taking the two presentations that are to be merged
      String file1 = "C:/poippt/presentation1.pptx";
      String file2 = "C:/poippt/presentation2.pptx";
      String[] inputs = {file1, file2};
      for(String arg : inputs) {
         FileInputStream inputstream = new FileInputStream(arg);
         XMLSlideShow src = new XMLSlideShow(inputstream);
         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");
      out.close();
   }
