Getting Started with Apache POI XLSF

First of all, you need to have the Java Development Kit (JDK) installed on your system. If you already have it then proceed to the Apache POI's download page to get the latest stable release in an archive. Extract the contents of the ZIP file in any directory from where the required libraries can be linked to your Java program. That is all!

Referencing Apache POI in your Maven-based Java project is even simpler. All you need is to add the following dependency in your pom.xml and let your IDE fetch and reference the Apache POI Jar files.

// create a new slide show
XMLSlideShow xmlSlideShow = new XMLSlideShow();
// initialize slide master object
XSLFSlideMaster xslfSlideMaster = xmlSlideShow.getSlideMasters().get(0);
// set Title layout
XSLFSlideLayout xslfSlideLayout = xslfSlideMaster.getLayout(SlideLayout.TITLE);
// create a new slide with title layout
XSLFSlide xslfSlide = xmlSlideShow.createSlide(xslfSlideLayout);
// select place holder
XSLFTextShape xslfTextShape = xslfSlide.getPlaceholder(0);
// set title
// save file
// close stream

XMLSlideShow slideShow = new XMLSlideShow();
// merge slides
for(String file : inputFiles){
  FileInputStream inputstream = new FileInputStream(file);
  XMLSlideShow xmlSlideShow = new XMLSlideShow(inputstream);
  for(XSLFSlide srcSlide : xmlSlideShow.getSlides()) {
// saving file
// close stream
