import java.util.List;

// This class demonstrates how to merge more than two PDF documents using the IronPDF library.
public class Main {
    public static void main(String[] args) throws IOException {
        // Create a list to hold the PDF documents
        List<PdfDocument> pdfList = new ArrayList<>();
        // Add existing PDF files to the list
        pdfList.add(PdfDocument.fromFile(Paths.get("assets/1.pdf")));
        pdfList.add(PdfDocument.fromFile(Paths.get("assets/2.pdf")));
        pdfList.add(PdfDocument.fromFile(Paths.get("assets/3.pdf")));
        // Merge all PDF documents in the list into one
        PdfDocument merged = PdfDocument.merge(pdfList);
        // Save the merged PDF document to the specified path
