Find Twitter hashtag with Java

Question

I'm going to do a sentimental analysis using twitter hashtag and I'm using Java for this project. How do I code Java to search for a specific hashtag and show the text?

This is what I've tried:

public static void main(String[] args) throws TwitterException {
    ConfigurationBuilder configurationBuider = new ConfigurationBuilder();
    configurationBuider.setDebugEnabled(true)
            .setOAuthConsumerKey("")
            .setOAuthConsumerSecret("")
            .setOAuthAccessToken("")
            .setOAuthAccessTokenSecret("");

    TwitterFactory tf=new TwitterFactory(configurationBuider.build());
    twitter4j.Twitter twitter=tf.getInstance();

    List<Status> status=twitter.getHomeTimeline();
    for(Status s:status){
        System.out.println(s.getUser().getName()+"    "+s.getText());
    }
}

}

What I get is only username and the text on timeline. Thank you for your help guys.

The question isn't entirely clear on what you are wanting to do but here is my interpretation:

You want to search the hashtags of the 20 most recent twitter posts on the timeline for a particular hashtag. If that post contains the hashtag, you want to display the user who posted it and the text of the post.

Below is what I believe to be a working example of this.

public static void main(String[] args) throws TwitterException {
ConfigurationBuilder configurationBuider = new ConfigurationBuilder();
configurationBuider.setDebugEnabled(true)
        .setOAuthConsumerKey("")
        .setOAuthConsumerSecret("")
        .setOAuthAccessToken("")
        .setOAuthAccessTokenSecret("");

TwitterFactory tf=new TwitterFactory(configurationBuider.build());
twitter4j.Twitter twitter=tf.getInstance();

// You can pull this in from user input, etc.
String hashTagToSearchFor = "testme";

List<Status> status=twitter.getHomeTimeline();
for(Status s:status){
    HashtagEntity[] hashTags = s.getHashtagEntities();
    for (HashtagEntity hashtag : hashTags) {
        if (hashtag.equals(hashTagToSearchFor)) {
            System.out.println(s.getUser().getName() + ": " + s.getText());

            // Assuming all hashtags are unique...
            continue;
        }
    }
}
}

Please let me know if I have made any incorrect assumptions and I will be glad to edit my answer to make adjustments.

Thanks man. I've tried your code and it showed up nothing. The code run successfully and I put "sport" in the Hashtag to search for but there is no comment that use #sport show up. – D POSITIVE Daisuke Jun 14 '17 at 09:52
do you have any social app that we can talk easier ? – D POSITIVE Daisuke Jun 14 '17 at 10:42
I do not unfortunately. The first thing I would do is to print out the whole list of hashtagentries for each post and see what they are because remember: twitter.getHomeTimeline() only returns 20 posts. You can explore the twitter4j javadoc to see what other methods are available to get posts. – Kylon Tyner Jun 14 '17 at 11:30
how can I print out the whole list ? – D POSITIVE Daisuke Jun 14 '17 at 14:05
Take out the if statement that is checking for hashtag.equals(hashTagToSearchFor) and instead just use System.out.println(hashtag) or possibly hashtag.toString() I don't know if it's a String or not off the top of my head – Kylon Tyner Jun 14 '17 at 14:40

Thank you man I already solved by doing this Kylon Tyner

    Query query = new Query("flood");
    QueryResult result = twitter.search(query);
    for (Status status : result.getTweets()) {
        System.out.println("@" + status.getUser().getScreenName() + " : " + status.getText() + " : " + status.getGeoLocation());
    }
