1. HTML Webpages and Java

Java provides API's to access resources over the network, for example to read webpages. The main classes which are used to read web resources is "java.net.URL" and "java.net.HttpURLConnection". URL can be used to define a web resources while "HttpURLConnection" can be used to access the web resource.

Tip

Please note that the Apache Foundation provides a powerful framework to to transmit and receive HTTP messages via the HttpClient . While I certainly would recommend to use this framework this article will only use standard Java libraries to explain the basics.

The examples for this article are contained in project "de.vogella.web.html".
