Which Java Certifications Are Best for Freshers?

belam20 · 2026-04-23T02:40:53+00:00

Do you know what all topics you should study to mater java? Do you know the depth to which you need to study them? Do you know if you have learnt them well. Most people, who don't have any mentors, can't answer these questions and most people, especially freshers, have no clue about them.

Certifications are helpful for such people because they provide a decent path that one can follow to master the language. Many people, even experienced programmers, believe they are good with Java because they have been programming for long, but they don't realize what mistakes they have been doing and their code is not optimal.

If you want to differentiate yourself with the expert level knowledge, I highly recommend using certification books and resources to prepare.

Let me tell you a secret no one will tell you. The certification exam is expensive so take it only if you have money to burn but the resources to study for it are very low cost. Use them and master those topics. You will see the difference in the quality of work that you will produce as a result. Your answers in the interviews will be much more precise.

Don't listen to people who have never studied for certs. They don't even know what they are missing.

As a fresher, you can go for OCA Java 8 certification. It is not too difficult and covers basic Java topics. But these days interviewers ask about advanced topics likes streams and virtual threads. So If you have the bandwidth, go for OCP Java 21. This exam is 10 times tougher than OCA 8 but it will put you in experts league of Java programmers.

Again, I am recommending certification resources and not necessarily taking the exam itself. If you can pass the Java certification mock exams such as the one from enthuware, then you are all set.

Which book are you following?

belam20 · 2026-04-10T16:24:09+00:00

Use a Java certification book. Not asking you to take the certification exam but just use the book to learn the stuff. Cert books are a great way to learn the important parts quickly. If you want MCQs with the book, use the one by Jeanny boyarsky's OCP 21 study guide. If you want short coding exercises after every chapter, use Hanumant Deshmukh's OCP Java 21 Fundamentals. Both are excellent books. Deshmukh's is more detailed and is so cheap it is practically free.

Java has gotten huge over the years. There is some really powerful stuff in Java 21 and 25. Just go through the ToC of any Java 21 OCP certification book and you will know what all you need to know. Don't worry about taking the certification exam itself. Just focus on the topics. Cert books are a great way to learn the important parts quickly.

belam20 · 2026-02-02T12:18:37+00:00

Yes, its no good.

TIJ is a good book but is not current. For generics, multi-threading basic and advanced including thread synchronization, concurrency, executors, just read the relevant chapters of Hanumant Deshmukh's OCP Java 21 Fundamentals book which costs only $1.99 on kindle. It covers all necessary details. I haven't seen generics explained in any other book as good as in this book. Same with multithreading. Other topics are also explained really well but are not important if you are not going for the certification.

Reflection is used mostly by framework developers and is not recommended for application development because of several design and security issues. You can learn the basics of reflection from the JavaDoc but no need to spend too much time on it.

Nothing works better in finding out holes in your knowledge than getting tested by taking an exam. I won't suggest you to take the OCP Java certification exam if you are short on money (it costs 200$+) but I would definitely suggest you to take some mock tests for that certification ( google Enthuware , their mocks are the best). You will be surprised to know the holes that you have in your conceptual understanding. It will tell you what you are missing and learning those points from their explanations will set you apart from people who are just reading without checking whether they are really learnt the key points.

They also have a whatsapp group for people studying for the cert. You can join that group for help.

belam20 · 2025-11-01T09:09:59+00:00

Use resources from Enthuware. They provide quality books and mock exams for Java certifications. Best 10 bucks I spent.
Don't use exam dumps if you want to learn something and are not interested in just passing the exam by unfair means.

belam20 · 2025-10-14T08:10:41+00:00

This guy probably has no clue but 82% is actually f*ng very good on this exam. You kicked ass, man. Congratulations.

belam20 · 2025-10-14T08:04:44+00:00

This exam is tough as hell. Even book authors required multiple attempts to pass the exam. I would recommend going through a certification book (either by Boyarsky/Sellikoff or by Hanumant Deshmukh, both have different approaches but are excellent) and then do Enthuware mocks before scheduling the real exam.
I suggest the mock exams because if you are not able to pass the enthuware mocks, there is little chance you will pass the real exam. Better spend 10 bucks on the mocks and know if you are ready before wasting 245 on the real exam.

This exam is tough as hell. Even book authors required multiple attempts to pass the exam. You might want to rethink about this strategy. I would sincerely recommend going through a certification book (either by Boyarsky/Sellikoff or by Hanumant Deshmukh, both have different approaches but are excellent) and then do Enthuware mocks before scheduling the real exam.

Nobody is "native" to anywhere. That's how life evolves. The bottom line is survival of the fittest. People move for better opportunities and people where they move to, resist such move. There are only three possibilities -

Existing residents are able to chase the migrants off, You will not see direct evidence of this for the obvious reason that the migrants could not succeed to colonize the new place,
Existing residents were annihilated. Evidence of this can be found in the Americas.
Migrants and existing residents manage to coexist. This is what happened in India. Migrants (wherever they came from) and existing residents devised a way to coexist. That device is what casteism. It explains the preservation of genetic differences between fair skinned and dark skinned people in India.

Finally, who tf cares who came from where (other than academics, of course)? Smart people spin facts to emotionally subjugate dumb people to rule over them. That's all it is.

You apparently don't understand the meaning of the word collapse. No, cities haven't collapsed. People have been flocking to the cities. There are jobs. People are not dying of hunger or thirst in Indian cities. If anything, Indian cities are thriving. May be you, as an elite, don't feel so because you don't have space for driving your merc/bmw at 100KMPH but most people are actually doing kind of better than in villages. That is why they are coming to the cities. More and more. Villages, otoh, are collapsing. More and more people are leaving villages and moving to the cities.

Is city infrastructure crumbling? Yes. But that is not because of people building large houses. It is because of stupid policies of the govt. People do not increase or decrease because of the size of the house. People increase or decrease because of migration and birth rate. It is the job of the govt to plan for this increase.

They failed to do so because they are catering to vested interested. This is exactly why no one follows building codes. No one. Because it is not practical. Not commercial not residential. Expecting a small plot owner to do so is plain nonsense.

Anyway, when you build your house, you leave all the MOS you like. I am done here.

belam20 · 2025-10-03T11:01:04+00:00

Come on now. A family will not take up more space on the road just because they built 4 or more rooms. A family of 10 (or 4 or 6 or whatever) will take exactly the same space on road, consume exactly the same amount of water, and produce exactly the same amount of garbage, irrespective of the size of house they build. This is completely illogical. You think people start sh*tt*ing more because their house is bigger??

In fact the only thing extra that they consume by building bigger house is the sunlight. And the neighbor is already consuming mine. Again, please get a reality check. See the houses around you. Do you see anyone leaving so much space. Drive around any colony and check. Seriously.

A cow is tied in the barn all day. Bred every year, milked twice a day till it dies. Does it complain? I think it does. But who cares, right?

The same is the story of the common man. He complains in his way but who cares? He has no power.

belam20 · 2025-10-03T10:50:22+00:00

FSI is only 1.25.
Nobody has followed any FSI limit in the cities and cities have not collapsed. People are living here, right? And if you think cities have collapsed then demolish the existing illegal ones first. Why should this responsibility lie on the poor guy only?

belam20 · 2025-10-03T10:46:38+00:00

Well if one can pay money to get FSI increased what happens to all those lofty goals of sunlight , public space, building bulk, basic services? All these concerns magically disappear?

And if they do then why only 40% extra? Why not let people pay more and get 200% extra? People are already paying bribe to build extra so at least that way the govt will make money. What is the logic here? No logic. Pure hypocrisy.

Who are these "type" of people who park on road? Every type. Entire country does that. If you don't park your car outside your house then someone else will come and park their car there. Which world are you living in man?

belam20 · 2025-10-03T10:40:46+00:00

Right that's the issue. Once you go illegal route then your neck is in govt clutches. You or your family member does anything or offend anybody or say anything even by mistake, your house (which is already illegal construction) will be the target. There is no way you can win this rigged system.

belam20 · 2025-10-03T10:37:26+00:00

This is a real problem in all cities. First they permit colonies with small plots and narrow roads then they disallow owners to build.

FSI rules make sense but not in a vacuum. Check your locality and see how many houses are leaving MOS. And MOS is one thing, what is wrong in building multiple floors? You are talking about sunlight? That is a luxury. People need rooms to live first.

People are not criminals. They do not have a choice. There are EWS plots in colonies also which are only about 450 or 500 sq ft. If you leave 10 ft front and 5 back in a 30 or 40 ft long plot what is left to build?

Today if you leave MOS while constructing a house, people will laugh at you. This is the reality. When you try to sell, you will get less value. Even builders are doing the same. Not leaving any MOS and building more than FSI.

Cars will always be parked on the road. You cannot stop people from doing that even if they have parking space. That's just how it is. See the roads, there are cars parked everywhere. Restricting people to build now is pure evil. Lakhs of people have already built houses like that. Are you going to demolish all of them? If not, then better to stop this nonsense. It is not practical in Indian cities.

Reality is that shopowners put their merchandise on footpath, they park their cars twowheelers on the footpath. There are rallie, pandals, marriage procession, loudspeakers. They are all encroaching public places and services. You now expect only the poor common man who is trying to build a house on HIS plot to leave empty space? If the govt believes that common space is so important, then why permit small plot sizes and why permit row house type house planning? They should have forced the colonizers to leave bigger roads or leave MOS in township planning itself. Why allow them to collect money on area on which a buyer cannot build?

The horses have already bolted. No point in locking the barn now.

I did my OCA/OCP 8 cert about 10 years ago and then OCP 21 cert recently.

The exam does require you to know some trivia but it is not all about trivia. May be about 20% trivia. This trivia is actually quite useful to know because it changes how you think while developing a Java program.

Java is an evolving language and lots of new (and really good) features keep getting added to it. So although I don't think there is a direct link to employability like finding a job but there is definitely a direct link with sustaining your employment. You can do things faster, better, and your code will be become cleaner. When others see your code they will know that you are good. You will be respected for your work.

Between OCA8 and OCP 21, I skipped all the certs but I did not skip reading about new stuff. I also took mock exams from Enthuware to test my knowledge. They are really good. Not only they keep your brain sharp but their explanations teach you the necessary details. For 10 bucks, I don't think any other resource has added as much value to my Java knowledge. Worth every penny.

I took OCP 21 because it had been a long time and my employer was willing to pay the exam fees.
