First, strings cannot be compared using == . Use Objects.equals
In general, probably, something like that should be:

Console console = System.console();
        if (console == null) {
            //do smth
            return;
        }

        String userInput = console.readLine("Пользователь, введи что-нибудь: \n");
        String[] answers = {"Привет", "Пока"};

        if (Strings.isNullOrEmpty(userInput)) {
            //do smth
            return;
        }

        System.out.printf("Пользователь говорит %s\n", userInput);

        if (Objects.equals(answers[0], userInput)) {
            System.out.println(answers[0]);
        } else {
            System.out.println(answers[1]);
        }
