Answer 1

After, version 1.1 of twitter api authentication is compulsory for all api calls , even for fetching public tweets and searching.. So, you have to add credentials by force:

 AccessToken accessToken = new AccessToken("ACCESS_TOKEN","TOKEN_SECRET");
 twitter.setOAuthAccessToken(accessToken);

Full code can be as follows:

        ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
        configurationBuilder
                .setOAuthConsumerKey(STAConstants.TWITTER_CONSUMER_KEY);
        configurationBuilder
                .setOAuthConsumerSecret(STAConstants.TWITTER_CONSUMER_SECRET);
        Configuration configuration = configurationBuilder.build();
        TwitterFactory twitterFactory = new TwitterFactory(configuration);
        Twitter twitter = twitterFactory.getInstance();
        AccessToken accessToken = new AccessToken("ACCESS_TOKEN","TOKEN_SECRET");
        twitter.setOAuthAccessToken(accessToken);
        System.out.println(twitter.getUserTimeline("twitter"));
