JAVA integration with twitter

Go to the URL https://apps.twitter.com/ and create a new application. Give access level in ‘Settings’ as ‘Read, Write and Access direct messages’. You will get both consumer key and secret.

And go to settings and check the permissions to read write and direct messages

Get

Consumer Key

Consumer Secret

see the screen

And also generate by clicking on generate access token it will display

Access Token

Access Token Secret.

Add dependency

<groupId>org.twitter4j</groupId>

<artifactId>twitter4j-core</artifactId>

</dependency>

Else we can add jar twitter4j-core

Code:

import twitter4j.Twitter;

import twitter4j.TwitterException;

import twitter4j.TwitterFactory;

import twitter4j.auth.AccessToken;

public class JavaTweet {

static String consumerKeyStr = "PASTE CONSUMER KEY HERE";

static String consumerSecretStr = "PASTE CONSUMER SECRET HERE";

static String accessTokenStr = "PASTE ACCESS TOKEN HERE";

static String accessTokenSecretStr = "PASTE ACCESS TOKEN SECRET HERE";

public static void main(String[] args) {

try {

Twitter twitter = new TwitterFactory().getInstance();

twitter.setOAuthConsumer(consumerKeyStr, consumerSecretStr);

AccessToken accessToken = new AccessToken(accessTokenStr,

accessTokenSecretStr);

twitter.setOAuthAccessToken(accessToken);

twitter.updateStatus("TWEET ON TWITTER EXAMPLE");

System.out.println("Successfully updated the status in Twitter.");

} catch (TwitterException te) {

te.printStackTrace();

}

That’s great. We have done it.

______________________________________________________________________________

We have also a neither way to tweet using java by Twitter REST API. For that we need

commons-codec-1.6.jar

commons-io-2.4.jar
commons-logging-1.1.3.jar
httpclient-4.3.1.jar
httpcore-4.3.jar
signpost-core-1.2.1.2.jar
signpost-commonshttp4-1.2.1.2.jar

All these jar files.

And code is as follows.

import oauth.signpost.OAuthConsumer;

import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;

import org.apache.commons.io.IOUtils;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.impl.client.DefaultHttpClient;

public class JavaRestTweet {

static String consumerKeyStr = "PASTE CONSUMER KEY HERE";

static String consumerSecretStr = "PASTE CONSUMER SECRET HERE";

static String accessTokenStr = "PASTE ACCESS TOKEN HERE";

static String accessTokenSecretStr = "PASTE ACCESS TOKEN SECRET HERE";

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

OAuthConsumer oAuthConsumer = new CommonsHttpOAuthConsumer(consumerKeyStr,

consumerSecretStr);

oAuthConsumer.setTokenWithSecret(accessTokenStr, accessTokenSecretStr);

HttpPost httpPost = new HttpPost(

"http://api.twitter.com/1.1/statuses/update.json?status=Hello%20Twitter%20Exammple.");

oAuthConsumer.sign(httpPost);

HttpClient httpClient = new DefaultHttpClient();

HttpResponse httpResponse = httpClient.execute(httpPost);

int statusCode = httpResponse.getStatusLine().getStatusCode();

System.out.println(statusCode + ':'

+ httpResponse.getStatusLine().getReasonPhrase());

System.out.println(IOUtils.toString(httpResponse.getEntity().getContent()));

}

That’s great. We have done it.

Intigration with Facebook Using java

Intigration with Facebook Using java

First we need register our app in

https://developers.facebook.com/

And in settings put domains as

https://sssss.com

And there we can get the appid and Secret Key

APPID

XXXXXXXXXXXXXX

Secret key

XXXXXXXXXXXXXXXX

And after settings all these go to

https://developers.facebook.com/tools/explorer/<APPID>/

And login with the credentials

After that click on the down arrow on get token, after that click on the checkbox publish_actions and click on get token after that token will generate. Copy that token and paste the token in the program.

Run the program.

Post will be posted on the user who has been logged in.
