In this example we will use an HTML Parser, Jsoup, in order to download images from a website.

jsoup is a Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods.

jsoup implements the WHATWG HTML5 specification, and parses HTML to the same DOM as modern browsers do.

In orderto get the src attributes of the <img> tags from a website. Then we download the file from the url we have aquired using a URL stream.

This code downloads images tha are directly accessible via URL. If they aren’t, an exception will be thrown.
