The URL provides a reasonably intelligible form to uniquely identify or address information on the Internet URLs are ubiquitous; every browser uses them to identify information on the Web Within Java s network class library, the URL class provides a simple, concise API to access information across the Internet using URLs All URLs share the same basic format, although some variation is allowed Here are two examples: http://wwwosbornecom/ and http://wwwosbornecom:80/indexhtm A URL specification is based on four components The first is the protocol to use, separated from the rest of the locator by a colon (:) Common protocols are HTTP, FTP, gopher, and file, although these days almost everything is being done via HTTP (in fact, most browsers will proceed correctly if you leave off the http:// from your URL specification) The second component is the host name or IP address of the host to use; this is delimited on the left by double slashes (//) and on the right by a slash (/) or optionally a colon (:) The third component, the port number, is an optional parameter, delimited on the left from the host name by a colon (:) and on the right by a slash (/) (It defaults to port 80, the predefined HTTP port; thus, :80 is redundant) The fourth part is the actual file path Most HTTP servers will append a file named indexhtml or indexhtm to URLs that refer directly to a directory resource Thus, http://wwwosbornecom/ is the same as http://wwwosbornecom/ indexhtm Java s URL class has several constructors; each can throw a MalformedURLException One commonly used form specifies the URL with a string that is identical to what you see displayed in a browser: URL(String urlSpecifier) throws MalformedURLException The next two forms of the constructor allow you to break up the URL into its component parts: URL(String protocolName, String hostName, int port, String path) throws MalformedURLException URL(String protocolName, String hostName, String path) throws MalformedURLException Another frequently used constructor allows you to use an existing URL as a reference context and then create a new URL from that context Although this sounds a little contorted, it s really quite easy and useful URL(URL urlObj, String urlSpecifier) throws MalformedURLException The following example creates a URL to Osborne s download page and then examines its properties:. vb.net ean 13 reader .NET EAN - 13 Barcode Reader for C#, VB .
