How much fact/conceptual memorization do I need to do?

[Stephen-Austin Murphy]

I'm not being lazy, but I would like to know:

I'm studying for the OCA and I'm trying to determine how much fact memorization I have to do.

Does the OCA ask questions like "which of the following are the relational operators" and "which of the following are equality operators"?

Thanks,
Steve

Steve,

Welcome to JavaRanch.

Does the OCA ask questions like "which of the following are the relational operators" and "which of the following are equality operators"?

This exam focuses on the usage and implementation of Java language features and concepts. Instead of asking you to select the relational or equality operators from a set of options, the exam might use them in code and query you on its output. For an example, you might get to answer a similar question in the exam on operators:

Question) What is the output of the following code?

class Operators {
    public static void main(String args[]) {
        int a = 10;
        int b = 20;
        System.out.println(a > 20 || b > 10);                    

        String emp = "Paul";
        String mgr = new String("Paul");
        System.out.println(emp == mgr);
    }
}

a)
true
true

b)
false
false

c)
true
false

d)
false
true


I wish you Good Luck with your exam preparation.

With respect,
Mala

And of course you'll also need some memorization about the Java classes from the API. When do you need to use property length, method length() or method size(); so you know for example when you see in a code snippet (like the example of Mala Gupta) something like anArray.length() that you have to choose Compilation fails option and you can proceed with the next question

Thanks, Roel.

Steve,

I've created a sample question based on Roel's answer for you:

Question) What is the output of the above code?

class Memorize {
    public static void main(String args[]) {
        int[] anArray = {10, 20, 30};
        System.out.println(anArray.length() * anArray[1]);
    }
}

a) 30
b) 60
c) Compilation error
d) Runtime exception


With respect,
Mala

Hi Roel and Mala,

Thank you so much for responding to my query and providing such helpful responses.

I really like the helpfulness and friendliness of both of you, and of this forum in general.

Mala, I saw your book while researching Java study books. Looks really nice!

Regards,
Steve
