How to create multilevel menu in TelegramBots API JAVA?

Question

Java

I can’t figure out how to make a multi-level inlineKeybords menu in JAVA in Telegram. I tried to add conditions for both callbackQuery and getMessage. The result is the same, the check fails and the menu does not open. Google searched all over. There are such tutorials in Python, but I don't even know the syntax in Python.

Answer 1

in this piece of code

execute(new SendMessage().setText(
                            update.getCallbackQuery().getData())
                            .setChatId(update.getCallbackQuery().getMessage().getChatId()));

we need to pass our menu handler method to the arguments, to which it is necessary to pass the chatId and the string value that comes from the CallbackQuery by the getData () method, the string value itself is already processed directly in the method that displays the menu

execute(menu(update.getCallbackQuery().getMessage().getChatId(), update.getCallbackQuery().getData());
