Answer 1

The name of this type of practice is scraping page, a variation of screen scraping. According to the Wikipedia page,

[..] a technique in which a computer program extracts data from video output from another program. [...] The key element that distinguishes the screen scraping from the Parsing it is customary that the exit that is being captured was intended to be viewed by a user human , instead of serving as input for another program [...] There are a number of synonyms, including: web scraping, page scraping, web page wrapping and HTML scraping (specific for webpages).

The example below, for Android, demonstrates this behavior:

public static void main(String... args) throws Exception {
    Document document = Jsoup.connect("/questions/88690").get();
    String question = document.select("#question .post-text p").first().text();
    System.out.println(question);
}

The end result is the extraction of the title of your question, 'Get news from a specific website!'.
