This code demonstrates how to copy slides from one PPT to another with Java Low Code API. You may call the other overloaded method CopySlide() by setting the uploaded file name, source slide index, destination slide index, and name of the destination presentation if it is different from the source presentation. Note that you need to upload the destination presentation also if you want to copy slides to a different presentation.
