JDownload manager is yet a primitive download manager which can be used to download multiple files simultaneously. It only supports HTTP connections hence It is unable to handle FTP/Proxy connections as of now. Developed entirely using Java/Swing uses Multithreading to download files simultaneously. Downloads can be paused/resumed. browser integration feature is not supported yet hence the user has to add the download link manually.
PS: source can be provided to anyone who is interested in extending this program to a more advanced download manager.
