public class AddComment {
    public static void main(String[] args) throws Exception{

        Presentation ppt = new Presentation();

        //Load a sample PowerPoint document
        ppt.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.pptx");

        //Add the author of the comment
        ICommentAuthor author = ppt.getCommentAuthors().addAuthor("E-iceblue", "Comment:");

        //Add a comment to the specified slide
        ppt.getSlides().get(0).addComment(author, "The first comment", new Point2D.Float(350, 170), new java.util.Date());

        //Save the result document
