##PircBotX in 3 Steps A brief getting started guide

import org.pircbotx.Configuration;
import org.pircbotx.PircBotX;
import org.pircbotx.hooks.ListenerAdapter;
import org.pircbotx.hooks.types.GenericMessageEvent;

public class MyListener extends ListenerAdapter {
        public void onGenericMessage(GenericMessageEvent event) {
                //When someone says ?helloworld respond with "Hello World"
                if (event.getMessage().startsWith("?helloworld"))
                        event.respond("Hello world!");

        public static void main(String[] args) throws Exception {
                //Configure what we want our bot to do
                Configuration configuration = new Configuration.Builder()
                                .setName("PircBotXUser") //Set the nick of the bot. CHANGE IN YOUR CODE
                                .addServer("") //Join the freenode network
                                .addAutoJoinChannel("#pircbotx") //Join the official #pircbotx channel
                                .addListener(new MyListener()) //Add our listener that will be called on Events

                //Create our bot with the configuration
                PircBotX bot = new PircBotX(configuration);
                //Connect to the server
  • Join the #pircbotx channel on and send ?helloworld . Your bot will respond with Hello world! Since its a GenericMessageEvent, it will also respond when private messaged. Congratulations, you just wrote your first bot!
