Question

I am trying to develop a basic twitter client which is able to read/update/send tweets and also searching through friends tweet and hash tagging. So far my app can login and send tweets to the wall. But i have no idea about the rest especially read and update tweets. Any information would be very helpful. Thank’s a lot..

After adding Twitter4J library to your build path.

To read tweets and send messges do like,
From your Auth Token and Key you retrieved make Twitter object,

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey(Constants.CONSUMER_KEY);
cb.setOAuthConsumerSecret(Constants.CONSUMER_SECRET);
cb.setOAuthAccessToken(token);
cb.setOAuthAccessTokenSecret(secret);
cb.setIncludeEntitiesEnabled(true);
TwitterFactory factory = new TwitterFactory(cb.build());
Twitter twitter = factory.getInstance();

Using this twitter object you can get Timelines,Mentions and send directMessages like..

twitter.getUserTimeline();
twitter.sendDirectMessage(screenName, text);
twitter.getMentions();

I suggest you to go to this links first,

1) Link for Twitter4J jar file

2) Link for Code Examples for Twitter4J

3) and JavaDoc for Twitter4J Api
