Welcome to the OpenStack wiki

The OpenStack Mission is to produce a ubiquitous Open Source Cloud Computing platform that is easy to use, simple to implement, interoperable between deployments, works well at all scales, and meets the needs of users and operators of both public and private clouds.

OpenStack is open source, openly designed, openly developed by an open community.

The OpenStack wiki is a collaboration tool for the community to publish various documents in a collaborative manner. Content may be out of date or inaccurate. Please refer primarily to other OpenStack websites for reference information (see below).

-URLs and save them to the local
-files in the directory of your choice:
-This Java program lets you download files from one or more URLs and save them in the directory where you want. This program takes destination directory for the files to save as first command line argument and URLs for the files as next command line arguments separated by space. Java provides URLConnection class that represents a communication link between the application and a URL. Invoking the openConnection method on a URL creates URLConnection object. Now get [[InputStream]] object from that connection and read the data. Finally write the data to the local file.
