Apache POI Reorder Slide

To reorder the powerpoint slides, Apache POI provides a method setSlideOrder(). This method switched slides by slide's positions. It is easy way and can handle by using Java program. Lets

see an example in which we are reordering first slide with the second slide.

Apache POI Reorder Slide Example

package poiexample;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFSlide;
public class ReOrderSlidesExample {	
 public static void main(String args[]) throws IOException{
	 try(XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("Javatpoint.pptx"))){
		  // Getting all the slides
		   List<XSLFSlide> slides = ppt.getSlides();  
		   // Selecting the second slide
		   XSLFSlide secondslide = slides.get(1);
		   // Getting on the top
		   ppt.setSlideOrder(secondslide, 0);
		   // Writing Modifications
		   FileOutputStream out = new FileOutputStream("Javatpoint.pptx");
		   ppt.write(out);
	 }catch(Exception e) {
		 System.out.println(e);
	 }
  }
}

Output:
