This project is a JAVA library which allows you to consume the Twitter API.

Configuration

In your pom.xml, add the following dependency and replace VERSION with the version you wish:

<dependency>
  <groupId>io.github.redouane59.twitter</groupId>
  <artifactId>twittered</artifactId>
  <version>VERSION</version>
</dependency>

If you are using Gradle Kotlin DSL, make sure you have MavenCentral among the available repositories:

repositories {
    mavenCentral()
    // [...]
}

Then add the following line to your dependencies block:

implementation("io.github.redouane59.twitter:twittered:VERSION")

To be able to see library logs, also add sl4j references :

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.7.30</version>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-simple</artifactId>
  <version>1.7.30</version>
</dependency>

In order to use your own developer credentials, you have several options :

Using a json file

File example :

{
  "apiKey": "xxx",
  "apiSecretKey": "xxx",
  "accessToken": "xxx",
  "accessTokenSecret": "xxx"
}

With program argument

Pass through java argument your file path like -Dtwitter.credentials.file.path=/your/path/to/json . Then instantiate the client like

TwitterClient client = new TwitterClient();

or

Using deserialization in your code

TwitterClient twitterClient = new TwitterClient(TwitterClient.OBJECT_MAPPER
                                                    .readValue(new File("/your/path/to/json"), TwitterCredentials.class));

With hard-coded values

TwitterClient twitterClient = new TwitterClient(TwitterCredentials.builder()
                                                            .accessToken("<access_token>")
                                                            .accessTokenSecret("<secret_token>")
                                                            .apiKey("<api_key>")
                                                            .apiSecretKey("<secret_key>")
                                                            .build());

NB : Your twitter credentials can be found in your twitter app page in the Key and tokens page.

Available methods

See :

• ITwitterClientV2.java
• ITwitterClientV1.java
• Tweet.java
• User.java

Code samples

See :

• ITwitterClientV2Test.java
• ITwitterClientV2AuthenticatedTest.java
• ITwitterClientV1Test.java

Basic examples

1. Init TwitterClient

TwitterClient twitterClient = new TwitterClient(TwitterClient.OBJECT_MAPPER
                                  .readValue(new File("/your/path/to/json"), TwitterCredentials.class));

2. Get Tweet object from tweet id and display some information

Tweet  tweet   = twitterClient.getTweet("1224041905333379073");
System.out.println(tweet.getText());
System.out.println(tweet.getCreatedAt());
System.out.println(tweet.getLang());
System.out.println(tweet.getLikeCount());
System.out.println(tweet.getRetweetCount());
System.out.println(tweet.getReplyCount());
System.out.println(tweet.getUser().getName());

3. Get User object from username and display some information

User   user   = twitterClient.getUserFromUserName("RedouaneBali");
System.out.println(user.getName());
System.out.println(user.getDisplayedName());
System.out.println(user.getDateOfCreation());
System.out.println(user.getDescription());
System.out.println(user.getTweetCount());
System.out.println(user.getFollowersCount());
System.out.println(user.getFollowingCount());
System.out.println(user.getPinnedTweet());
System.out.println(user.getPinnedTweet());
System.out.println(user.getLocation());
System.out.println(user.getId());
System.out.println(user.getUrl());

Contribution

If you want to contribute to the project, don't hesitate to submit pull requests. To add a new feature :

• Create the interface method in the related interface ( e.g ITwitterClientV2.java)
• If needed, add the endpoint URL in URLHelper.java
• Implement your method in the child class ( e.g TwitterClient.java)
• Don't forget to add your unit tests in src/test/java/io/github/redouane59/twitter/unit

Code style is also available in .idea/codeStyles/GoogleStyle.xml file.

Special thanks

I would like to give special thanks to @hypr2771 @mmornati @andypiper @igorbrigadir @sparack for having helped me building this Twitter API library for Java. The tool is now working and I hope that students, junior and senior developers will enjoy it, being able to play easily with twitter data using Java programming language.
