Twitter - Adding followers of a person to your friends list and follow all of them Friday, June 5, 2009

I've been playing around with one of Twitter API implemetation Twitter4j which is awesome and I could do a lot of things with it. Here is one of my implementation to automate adding friends to yourself with a Java program. Make sure you have twitter4j in your build path before trying this program.

Here is how it works,

1. Select a twitter user

2. Fetch the list of his followers

3. Add them as your friends

4. Follow all of them

Java source

package com.twittervis.core;

import java.util.List;

import twitter4j.Twitter;

import twitter4j.User;

class GetFollowers {

public static void main(String[] args) {

//Create twitter object with user name

Twitter twitter = new Twitter("your-twitter-user-name", "password");

try {

//Get the list of the person wh

ose friends you want to add as your friend

List friends = twitter.getFollowers("selected-twitter-user");

for (int j = 0; j &gt friends.size();j++){

//convert twitter user id from int to String

String myString = Integer.toString(friends.get(j).getId());

//make each user of the list as your friend

//true is to follow the person, else only he is made friend

twitter.createFriendship(myString, true);

}

} catch (Exception e) {

e.printStackTrace();

}

}

}

Now, This program adds the followers of a particular user as your friends, and you'll be following them. I'm working on creating mashups with Twitter + Google App Engine(GAE)
