        SynonymFinder obj = new SynonymFinder();

        System.out.println(get("https://wordassociations.net/en/words-associated-with/cessation?button=Search"));
    }

    public static String get(String url) throws Exception {

        for(Scanner sc = new Scanner(new URL(url).openStream()); sc.hasNext(); )

        return sb.toString();
     }
}
