// Create your bot passing the token received from @BotFather
TelegramBot bot = new TelegramBot("BOT_TOKEN");

// Register for updates
bot.setUpdatesListener(updates -> {
    // ... process updates
    // return id of last processed update or confirm them all
    return UpdatesListener.CONFIRMED_UPDATES_ALL;
// Create Exception Handler
}, e -> {
    if (e.response() != null) {
        // got bad response from telegram
        e.response().errorCode();
        e.response().description();
    } else {
        // probably network error
        e.printStackTrace();
    }
});

// Send messages
long chatId = update.message().chat().id();
SendResponse response = bot.execute(new SendMessage(chatId, "Hello!"));
