import com.google.gson.Gson;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

// Let's make this class to represent our response from random.cat
class ImageObject {
    public String file;
}

public class CatImage {
    public static void main(String[] args) throws Exception {

        // Open a connection to the website
        URL site = new URL("https://aws.random.cat/meow");
        URLConnection siteConnection = site.openConnection();

        // Make a buffered reader so we can get the site's content
        BufferedReader in = new BufferedReader(new InputStreamReader(siteConnection.getInputStream()));
        StringBuilder sb = new StringBuilder();
        String inputLine;

        // Read the site's input
        while ((inputLine = in.readLine()) != null) {
            sb.append(inputLine);
        }

        // Sick now we can close our reader
        in.close();
        String websiteContent = sb.toString();

        // Let's grab some Json
        Gson gson = new Gson();
        ImageObject image = gson.fromJson(websiteContent, ImageObject.class);

        // And now we got our stuff!
        System.out.println(image.file);
    }
