I am a java developer with 2+ years of experience from India but from the last 6 months I have been working on python. Now, my question is I have been thinking of buying voucher because of sale as I have read most of the topics from OCA 8 so the time with me is 6 months to complete both programmer I and II. I was thinking of going for 11 certification but launch of book java 11 programmer II in on April 2020 that would be difficult.

Q-1) How much time would I require to get ready for certification and If I have 5 months to do so what will you suggest me to plan study?
Q-2) Not buy voucher in sale and later get ready for java 11 certification.

Note :- I know java 7 so to learn the new concepts I started to study java 8 as I think reading topics of java 11 directly would make it difficult and there are no books available also.

I live in Germany, and here there is no sale for the Oracle vouchers

At any rate, to answer your question, 6 months is very little time to get certified for both programmer I and II (not impossible, but very hard). Last week I've passed my OCP8 exam and I can tell you my background/experience. I have 15+ years of professional software engineering experience. Pure java development would be only the last 1.5 years (plus other time spent privately on open-source projects, etc...). Last year I've studies for my OCA exam about 4 months (at home after work and on week-ends). This year it took me ~6 months (with a few weeks pause in between) to properly prepare for the OCP exam. This second one is much harder than the first one (the content is about 1.5 time more). For Java 8 there is a lot of additional material out there, but for Java 11 not so much.

So my recommendation would to get a voucher for the first exam (especially if it's on sale) and go form there. This will also help you asses the exam, the material and your ability to study for this exam having a dead-line in sight. I know that J11 has only one certification that required both exams to be completed. For J8 you've actually gotten 2 certifications, one after passing each exam. So you might want to think about that as well when you make your decision J8 vs J11.

cheers.

There are lots of books available teaching Java8/11, just no study guides yet for the Java11/OCPII exam. I would suggest you need to become fluent with Java8 (streams, functional style, λs) and Java9 (modules) and Java10 (var) etc. before you even start revising for the exam. If you are starting from Java7, I think six months is very over‑optimistic. R J Arzki was starting from proficiency in Jaa8, and therefore had much less new knowledge to learn.

I think you are right, I should be only focusing on JAVA 8 OCA certification right now. I saw the topics and R.J is right that OCP 8 has 1.5% more topics and is harder than OCA. Lastly my aim is to be fluent with JAVA 8 certification is just a part of it to challenge myself, even if I pass and don't have deeper knowledge it won't make any sense. I want one help from any Rancher here as I am working professional I get on weekends and some time in the evening so how should I move ahead with a goal of clearing OCA 8 in six months.

That isn't what I said. I said you had to learn Java8.

. . . OCP 8 has 1.5% more topics . . .

1.5% more topics doesn't mean anything. Java8 has lots of stuff in which you don't know.

. . . I am working professional . . .

What has your employer said about OCA8?

goal of clearing OCA 8 in six months.

RJA and I both doubt whether that is possible. Make it your goal to learn the new features of Java8 in six months.

My employer is supporting me for any certifications anytime. I have completed OCA programmer I book once but its just that due to my health condition I was away from this industry for like 8 months. You are 100% correct that JAVA is hard to master anyone who have read the complete reference can relate. I am going for it that'f for sure but how I should move ahead that is a question. It would be great if you can help me Ritchie

Where did I say that Java® (not JAVA) is hard to master? I said there is much to learn. Not the same.

read the complete reference . . .

What do you mean by, “complete reference”?

Different version of what I said earlier: the more you post on this website for us to see, the better.

I thought you might have meant that book. There are much better books available. Try Modern Java in Action by Urma Fusco and Mycroft (Manning 2017). Older editions of that book were called Java 8 in Action or maybe Java 8/9 in Action.

Please don't quote the whole of an old post; who wants to read what I wrote twice?
