How to make my TelegramBot send several messages in a row?

I make a TelegramBot that is going to count my expanses, and one of its functions should be counting expenses for the specific period of time and showing these expenses. I use MySQL DB, so I am querying and it works, but sendMessage of TelegramAPI allows to send messages with the maximum length 4096UTF-8 characters, which may be not sufficient if i have big database. So how can I make the bot to send several messages? E.g.

 public SendMessage onGetExpensesCommand(Message message, String[] dateFrames){
    SendMessage returnMessage = new SendMessage();
    returnMessage.setText(getExpensesFromDB(String[] dateFrames));//queries DB
    returnMessage.setReplyToMessageId(message.getMessageId());
    returnMessage.setChatId(message.getChatId().toString());
    return returnMessage;
}

Later message is sent.

i don't know java but i made a nice function for it in python. i build the message string. one the message string is finished, i create a list and i split that long message in many small (the maximum size allowed by telegram) messages and i add them inside the list.

At the end i run a for loop and i use sendMessage method to send all of them one by one. i add a time sleep between them to make sure not to hit telegram flood limits.

I store in a variable the first sent message, and once the loop is ended i send a message "click here to go to the first message" in reply to the first sent message.

the only difficult part of this is if you have to handle formatting too
