How do I call the result of a method within that same method as a parameter for another method?-CodePudding

I am trying to create a chatbot as part of a tutorial, and have an answer method calling from an interface:

    @Override public String answer(String question) {
        if (hasAI() == false) {
            return "Excellent";
        }
        else return QA.getOrDefault(question, "Interesting question.");
    }

QA here is a simple immutable HashMap containing a bunch of questions and answers. So you enter a question, and get a corresponding answer if it has an AI, otherwise it just says "excellent". However, I am trying to call a method that stores records of the chat within that method, as per the tutorial.

    public void addChatRecord(char type, String chat) {
        if (type == 'Q' || type == 'A') {
            chatRecords.add(type   ":"   chat);
        }
        else {
            System.out.println("Wrong type of the chat.");
        }
    }

However, I am having some trouble trying to figure out how exactly to call the method addChatRecord within the answer method.

    @Override public String answer(String question) {
        if (hasAI() == false) {
            return "Excellent";
        }
        else return QA.getOrDefault(question, "Interesting question.");
        addChatRecord('A', String answer);
    }

What should I put where String answer is? I'm trying to get the returned value of a method within that same method, and that is confusing me.

Assign the answer to a variable, and use that variable as both your method parameter and return value:

@Override public String answer(String question) {
    String answer = hasAI()
        ? QA.getOrDefault(question, "Interesting question.")
        : "Excellent";
    
    addChatRecord('A', answer);

    return answer;
}

Simply use a variable:

 @Override public String answer(String question) {
        String answer;
        if (!hasAI()) {
            answer=  "Excellent";
        }
        else {
            answer= QA.getOrDefault(question, "Interesting question.");
        }
        addChatRecord('A', answer);
        return answer;
    }
