Public OutputStream getOutputStream() throws IOException Returns the input stream of the URL connection for reading from the resource. Public InputStream getInputStream() throws IOException The default value is false because many types of URLs do not support being written to.

Passes in true to denote that the connection will be used for output. The default value is true because clients typically read from a URLConnection. Passes in true to denote that the connection will be used for input. Returns the value of this object's ifModifiedSince field. Returns the value of the expired header field. Returns the value of the last-modified header field. Returns the value of the content-type header field. Returns the value of the content-length header field. Returns the value of the content-encoding header field. Retrieves the contents of this URL connection. The URLConnection class has many methods for setting or determining information about the connection, including the following − Sr.No. If you connect to a URL that represents a JAR file, the openConnection() method returns a JarURLConnection object, etc. If you connect to a URL whose protocol is HTTP, the openConnection() method returns an HttpURLConnection object. The openConnection() method returns a, an abstract class whose subclasses represent the various types of URL connections. Live DemoĪ sample run of the this program will produce the following result − Output URLConnections Class Methods A URL is entered on the command line, and the URLDemo program outputs each part of the given URL. The following URLDemo program demonstrates the various parts of a URL. Opens a connection to the URL, allowing a client to communicate with the resource. Public URLConnection openConnection() throws IOException Returns the default port for the protocol of the URL. Some of the methods in the URL class include the following − Sr.No. The URL class contains many methods for accessing the various parts of the URL being represented. Public URL(URL context, String url) throws MalformedURLExceptionĬreates a URL by parsing together the URL and String arguments. Public URL(String url) throws MalformedURLException Identical to the previous constructor, except that the default port for the given protocol is used. Public URL(String protocol, String host, String file) throws MalformedURLException Public URL(String protocol, String host, int port, String file) throws MalformedURLExceptionĬreates a URL by putting together the given parts.

The URL class has several constructors for creating URLs, including the following − Sr.No. The class represents a URL and has a complete set of methods to manipulate URL in Java. Notice that this URL does not specify a port, in which case the default port for the protocol is used. The following is a URL to a web page whose protocol is HTTP − The path is also referred to as the filename, and the host is also called the authority. A URL can be broken down into parts, as follows −Įxamples of protocols include HTTP, HTTPS, FTP, and File.
