Hi,

I have so far done programming in Java language only. I am planning to appear for OCA Java 8 exam soon and so far done with reading other topics covered in OCA 8 exam but yet to start learning functional programming and lambda.

How much (in-depth) knowledge of Java functional programming is required for OCA 8?

Also which book will be sufficient to refer for this topic for the exam? I have so far read OCA Java 7 exam books and yet to read (looking for) good book for OCA 8 exam.

Thanks,
Riddhi

In the OCP is where you will require deep knowledge.
The exam objective for the OCA is very clear:

- Write a simple Lambda expression that consumes a Lambda Predicate expression.

It's more about syntax and learn to recognize wrong statements.

Hi Riddhi -

The OCA Java SE 8 Programmer I Certification includes an introduction to the functional style programming.

You would need to know the following on this topic for the 1Z0-808 exam:

i) Functional interfaces
ii) When to use lambda functions
iii) Lambda syntax
iv) How to use Lambda functions
    a. variables that can be assigned lambda functions,
    b. passing lambda functions to methods as parameters
v) Interface Predicate

All these topics are included in my OCA Java SE 8 Programmer I Cert book.

Good Luck to you.

With much respect,
Mala
