Sometime back I was looking for a way to search Google using Java Program. I was surprised to see that Google had a web search API but it has been deprecated long back and now there is no standard way to achieve this. Basically google search is an HTTP GET request where query parameter is part of the URL, and earlier we have seen that there are different options such as Java HttpUrlConnection or Apache HttpClient to perform this search. But the problem is more related to parsing the HTML response and get the useful information out of it. That’s why I chose to use jsoup that is an open source HTML parser and it’s capable to fetch HTML from given URL. So below is a simple program to fetch google search results in a java program and then parse it to find out the search results.

package com.journaldev.jsoup;

import java.io.IOException;
import java.util.Scanner;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class GoogleSearchJava {

	public static final String GOOGLE_SEARCH_URL = "https://www.google.com/search";
	public static void main(String[] args) throws IOException {
		//Taking search term input from console
		Scanner scanner = new Scanner(System.in);
		System.out.println("Please enter the search term.");
		String searchTerm = scanner.nextLine();
		System.out.println("Please enter the number of results. Example: 5 10 20");
		int num = scanner.nextInt();
		String searchURL = GOOGLE_SEARCH_URL + "?q="+searchTerm+"&num="+num;
		//without proper User-Agent, we will get 403 error
		Document doc = Jsoup.connect(searchURL).userAgent("Mozilla/5.0").get();
		//below will print HTML data, save it to a file and open in browser to compare
		//If google search results HTML change the <h3 class="r" to <h3 class="r1"
		//we need to change below accordingly
		Elements results = doc.select("h3.r > a");

		for (Element result : results) {
			String linkHref = result.attr("href");
			String linkText = result.text();
			System.out.println("Text::" + linkText + ", URL::" + linkHref.substring(6, linkHref.indexOf("&")));


Below is a sample output from above program, I saved the HTML data into file and opened in a browser to confirm the output and it’s what we wanted. Compare the output with below image. Google Search API Java, java google search, google search java program

Please enter the search term.
Please enter the number of results. Example: 5 10 20

That’s all for google search in a java program, use it cautiously because if there is unusual traffic from your computer, chances are Google will block you.

                  It’s easier if you open directly to predefined browser if (Desktop.isDesktopSupported()) try { Desktop.getDesktop().browse(new URI(searchURL)); } catch (IOException e1) { e1.printStackTrace(); } catch (URISyntaxException e1) { e1.printStackTrace(); } and you don’t need the number of results, just the searchTerm String searchURL = GOOGLE_SEARCH_URL + “?q=”+searchTerm
