How can I use Jsoup to extract specific information from a website in Java?

Parsing a Website for Information with Jsoup

To extract information from a web page into your Java program, you can utilize HTML parsers such as Jsoup. Jsoup stands out as it employs jQuery-like CSS selectors and simplifies iteration through extracted data.

To begin, include the latest Jsoup JAR file in your classpath. Here's an example of how to scan a Best Buy item page and extract title, price, and description:

<code class="java">import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;

public class WebsiteScanner {

    public static void main(String[] args) throws Exception {
        String url = "https://www.bestbuy.com/site/sony-wh-1000xm5-wireless-bluetooth-noise-canceling-over-the-ear-headphones-black/6497835.p?skuId=6497835";
        Document document = Jsoup.connect(url).get();

        String title = document.select("h1.v-pdp-product-title").text();
        String price = document.select(".v-pdp-price-amount").text();
        String description = document.select(".v-pdp-main-description").text();
