This short tutorial guides on how to merge PowerPoint presentations using Java. It provides detailed steps including the required resources for developing the application, a list of programming tasks to accomplish the task, and a runnable sample code to combine multiple PowerPoints into one using Java. You will also learn to control the process by adding slides based on some criteria in your application.

Steps to Combine Slides using Java

1. Set the IDE to use Aspose.Slides for Java to develop PPTX combiner
2. Load the main presentation using the Presentation class
3. Instantiate multiple Presentation objects by loading the desired presentations
4. Loop through all the Slide in each presentation
5. Call the addClone() method for the main presentation to add slides from the desired presentations
6. Save the main presentation on the disk having all the appended slides

These steps summarize the process to merge slides using Java. The process is commenced by loading the main presentation where other presentations are to be appended followed by loading all the desired presentations in separate Presentation class objects. In the next steps, all the slides in the desired presentations are iterated and appended to the main presentation using the addClone() method of the slide collection in the main presentation before saving them on the disk.

Code to Combine PowerPoint Slides using Java

This code demonstrates the process to merge PowerPoint files using Java. Each presentation has a collection of slides by default where slides are present and contains a variety of methods including the addClone() method to copy a slide from the source to the destination presentation. You may use different overloaded methods of the addClone() method and also apply filters based on slide id or name to append the selected slides only.
