This sample code shows extracting attachments of PDF document using Java


    package com.aspose.asposecloudpdfusecases.attachments;

    import java.io.File;
    import java.nio.file.Path;
    import java.nio.file.StandardCopyOption;
    import com.aspose.asposecloudpdf.api.PdfApi;
    import com.aspose.asposecloudpdf.model.AttachmentResponse;

    public class AttachmentGetById {
        public static void Extract() {
            String REMOTE_FOLDER    = "Your_Temp_Pdf_Cloud";
            String LOCAL_FOLDER     = "c:\\Samples";
            String PDF_DOCUMENT     = "sample_file_with_attachment.pdf";
            Integer ATTACHMENT_INDEX  = 1;

            try {
                PdfApi pdfApi = new PdfApi(API_KEY, API_SECRET);

                // upload local PDF file to remote storage
                File file = new File(Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString());
                pdfAPi.uploadFile(Path.of(REMOTE_FOLDER , PDF_DOCUMENT).toString(), file, null);
                System.out.println(String.format("File '%s' successfully uploaded!", Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString()));

                AttachmentResponse response = pdfAPi.getDocumentAttachmentByIndex(PDF_DOCUMENT, ATTACHMENT_INDEX, null, REMOTE_FOLDER);
                if (response.getCode() != 200)
                    System.err.println("Error: unexpected error when extracting attachment! '" + response.getStatus() + "'");
                else{
                    File f = pdfAPi.getDownloadDocumentAttachmentByIndex(PDF_DOCUMENT, ATTACHMENT_INDEX, null, REMOTE_FOLDER);
                    String attachmentName = response.getAttachment().getName();
                    // download changed PDF file from remote folder...
                    java.nio.file.Files.copy(Path.of(f.getPath()), Path.of(LOCAL_FOLDER, attachmentName), StandardCopyOption.REPLACE_EXISTING);
                    System.out.println(String.format("File '%s' successfully dowloaded!", Path.of(LOCAL_FOLDER, attachmentName).toString()));                
                    System.out.println("Successfully extracted attachment in document ! '" + attachmentName + "'");
                }
            }
            catch (Exception e) {
