README.md

A java library to download files and process the download speed,progress and other things

• Download files easy
• Check download speed
• Check download progress
• Directly cast download objects
• Download Text
• Convert file sizes (MB;GB;KB. )

Downloader downloader = new Downloader(false); downloader.downloadFileToLocation("https://github.com/MrMarnic/JIconExtract/releases/download/1.0/JIconExtract.jar","C:\\Downloads\\download.zip"); 

Add Handler (Check Speed,progress. ):

Downloader downloader = new Downloader(false); downloader.setDownloadHandler(new CombinedSpeedProgressDownloadHandler(downloader) < @Override public void onDownloadSpeedProgress(int downloaded, int maxDownload, int percent, int bytesPerSec) < System.out.println(SizeUtil.toMBFB(bytesPerSec)+"/s " + percent + "%"); >@Override public void onDownloadFinish() < super.onDownloadFinish(); System.out.println("Download finished"); >>); downloader.downloadFileToLocation("https://github.com/MrMarnic/JIconExtract/releases/download/1.0/JIconExtract.jar","C:\\Downloads\\download.zi"); 

• DownloadSpeedDownloadHandler (check speed)
• DownloadProgressDownloadHandler (check progress)
• CombinedSpeedProgressDownloadHandler (check speed and progress)

public class ExampleDownloadHandler extends DownloadHandler < public DownloadProgressDownloadHandler(Downloader downloader) < super(downloader); >@Override public void onDownloadStart() < >@Override public void onDownloadFinish() < timer.cancel(); >@Override public void onDownloadError() < timer.cancel(); >> 

Syntax: SizeUtil.toMBFB() = toMegaBytesFromBytes SizeUtil.toGBFB() = toGigiaBytesFromBytes

double mb = SizeUtil.toMBFB(2000000000); double kb = SizeUtil.toKBFB(1000000);

How to implement the FileDownloaderDelegate

Simple! Create a FileDownloader and pass your class that implements FileDowloaderDelegate to it.

The class needs to implement the following methods:

public void didStartDownload(FileDownloader fileDownloader) public void didProgressDownload(FileDownloader fileDownloader) public void didFinishDownload(FileDownloader fileDownloader) public void didFailDownload(FileDownloader fileDownloader)

public class MyClass implements FileDownloaderDelegate < void startDownloads()< FileDownloader fileDownloader = new FileDownloader(this); // Pass in delegate // as self. fileDownloader.setUrl("http://eoimages.gsfc.nasa.gov/images/imagerecords/45000/45449/Bolivia_amo_2010235_lrg.jpg"); fileDownloader.setLocalLocation("/Users/jesse/Desktop/ppppppppp.jpg"); fileDownloader.beginDownload(); > @Override public void didStartDownload(FileDownloader fileDownloader) < System.out.println("Download started"); > @Override public void didProgressDownload(FileDownloader fileDownloader) < String kbPerSecond = "Calculating. "; if (fileDownloader.getKbPerSecond() != null) < kbPerSecond = fileDownloader.getKbPerSecond() + " kb/s"; > System.out.println(fileDownloader.getPercentComplete() + " at " + kbPerSecond); > @Override public void didFinishDownload(FileDownloader fileDownloader) < // do stuff > @Override public void didFailDownload(FileDownloader fileDownloader) < // do stuff > >

// fileDownloader is an initialized FileDownloader fileDownloader.getKbPerSecond(); // returns String fileDownloader.fileDownloader.getLocalLocation(); // returns String fileDownloader.getUrl(); // returns String fileDownloader.getBytesWritten(); // returns int fileDownloader.getTotalTimeToDownload(); // returns String fileDownloader.getDownloadBeginTime(); // returns long fileDownloader.getDownloadEndTime(); // returns long fileDownloader.getPercentComplete(); // returns String fileDownloader.isDownloading(); // returns boolean

README.md

File downloader written in Java. Uses thread to download files in multiple connections to fully utilize internet speed.

• Multi-threaded. Download files in multiple connections if server accepts range header.
• Retries downloading file on failure.

Create an instance of DownloadManager using the constructor DownloadManager(int concurrentDownload) . Set DownloadListener to the instance of DownloadManager using setDownloadListener . Set path and max connection per downloads, DownloadManager.Config.path = «D:\\downloads» and DownloadManager.Config.connections = 8 Create an instance of URL using the file url and call downloadManager.download(url) .

public static void main(String[] args) < try < DownloadManager downloadManager = new DownloadManager(100); // 100 concurrent downloads DownloadManager.Config.path = "H:\\transfer"; DownloadManager.Config.connections = 8; downloadManager.setDownloadListener(new DownloadListener() < @Override public void onDownloadStarted(Downloader.DownloadStatus downloadStatus) < System.out.println(downloadStatus.getFileName() + " download started."); > @Override public void onDownloadFinished(Downloader.DownloadStatus downloadStatus) < System.out.println(downloadStatus.getFileName() + " download finished. File size " + downloadStatus.getFileSize() + ", downloaded " + downloadStatus.getDownloadedSize()); > @Override public void onDownloadFailed(Downloader.DownloadStatus downloadStatus) < System.out.println(downloadStatus.getFileName() + " download failed. File size " + downloadStatus.getFileSize() + ", downloaded " + downloadStatus.getDownloadedSize()); > >); downloadManager.download(new URL("https://pop-iso.sfo2.cdn.digitaloceanspaces.com/19.04/amd64/intel/3/pop-os_19.04_amd64_intel_3.iso".replaceAll(" ", "%20"))); > catch (IOException e) < e.printStackTrace(); > >

• download(URL url) — Downloads the file from the URL and returns a String containing the process Id.
• cancelDownload(String processId) — Cancels a download according to processId.
• getDownloadStatus(String processId) — Returns an instance of DownloadStatus containing download information according to the process Id.
• getDownloadList() — Returns an ArrayList containing all the download processes.
