        File File=new File(Filepath);
        fileName=File.getAbsolutePath().substring(File.getAbsolutePath().lastIndexOf("\\") 1);
        System.out.println(fileName);
        
        
        File file = new File(System.getProperty("user.dir") "\\src\\test\\resources\\Download\\" fileName "");
        
        PDDocument doc = PDDocument.load(file);
        int numberOfPages = getPageCount(doc);
        System.out.println("The total number of pages " numberOfPages);
        String content = new PDFTextStripper().getText(doc);
        doc.close();
    return content;
}

static String Filepath=System.getProperty("user.dir") "\\src\\test\\resources\\Download\\";

can you please help for this

CodePudding user response：

Well you can simply list all files in folder and take the newest

Like something:

File f = new File("download_folder");
String[] pathnames = f.list();

then you can use for-loop to find what you need

Create a method to check whether a file is fully downloaded or not.
Call that method wherever it's required.

Method to check file is downloaded or not: This method is to search for specific file with partial or full text in download folder for given time and returns the boolean result.

@param fileText - Partial or full file name
@param fileExtension - .pdf, .txt
@param timeOut - How many seconds you are expecting for file to be downloaded.

    public static boolean isFileDownloaded(String fileText, String fileExtension, int timeOut) {
        String folderName = "location of download folde";
        File[] listOfFiles;
        int waitTillSeconds = timeOut;
        long passedTimeInSeconds = 0;
        boolean fileDownloaded = false;

        long waitTillTime = Instant.now().getEpochSecond()   waitTillSeconds;
        while (passedTimeInSeconds < waitTillTime) {
            listOfFiles = new File(folderName).listFiles();
            for (File file : listOfFiles) {
                String fileName = file.getName().toLowerCase();
                if (fileName.contains(fileText.toLowerCase()) && fileName.contains(fileExtension.toLowerCase())) {
                    fileDownloaded = true;
                    break;
                }
            }
            if (fileDownloaded) {
                break;
            }
        }
        return fileDownloaded;
    }

Call the isFileDownloaded method:

    if (!isFileDownloaded(fileName, ".pdf", 30)) {
                System.out.println("File is not downloaded. Expected file is "   fileName   ".pdf");
            }else{
                System.out.println("File is downloaded.);
           }
