The code

public void onUpdateReceived(Update update) {
        SendMessage sendMessage = new SendMessage();

        if (update.hasCallbackQuery()) {
            sendMessage.setChatId(update.getCallbackQuery().getMessage().getChatId());
            String callbackText = update.getCallbackQuery().getData();
            if (callbackText.equals("toUSD")) {
                sendMessage.setText("Напишите сумму:");
                System.out.println(sendMessage.getChatId());  //Проверка Chat ID
            } else if (callbackText.equals("toEUR")) {
                sendMessage.setText("Напишите сумму:");
            }
        }
}

Checked with debug, but everything is fine. Chat ID is correct. But the message is not coming to the chat.

Why is this happening?

Answer 1

Because you create an object sendMessage, put text into it sendMessage.setText("Напишите сумму:");, and then nothing happens.
You need a method .execute(sendMessage)fromDefaultAbsSender
