// Specify the file to be attached
String filePath = "path/to/your/file.pdf";

// Create an attachment
FileAttachment fileAttachment = new FileAttachment(pdfDocument.getPages().get_Item(1), filePath);

// Set the attachment's appearance
fileAttachment.setIcon(FileIcon.Paperclip);
fileAttachment.setColor(Color.getBlue());

// Add the attachment to the PDF document
pdfDocument.getPages().get_Item(1).getAnnotations().add(fileAttachment);

Saving the modified PDF

After attaching the files, save the modified PDF document to your desired location:

// Save the PDF with attachments
pdfDocument.save("output.pdf");
