Can Java Programmatically Search Google Using Its Public API?

Searching Google Programmatically with Java API

Is it possible to search Google programmatically from a Java application? If so, is there a Java API to facilitate this process?

Google provides a public search web service API that returns results in JSON format, available at http://ajax.googleapis.com/ajax/services/search/web. To interact with this API, you can utilize Java's java.net.URL and java.net.URLConnection classes to handle HTTP requests.

Furthermore, libraries like Google Gson can assist in converting JSON responses into Java objects. Combining these elements, you can search Google and parse the results programmatically.

For example, consider the following Java code:

//...
URL url = new URL(google + URLEncoder.encode(search, charset));
Reader reader = new InputStreamReader(url.openStream(), charset);
GoogleResults results = new Gson().fromJson(reader, GoogleResults.class);

// Show title and URL of 1st result.
Copy after login
