the ultimate guide to Java certification

“Do I really need a Java certification?” As a Java developer, it’s a question you may ask yourself at some point in your career.

Despite the fact that most Java professionals learn as they earn, without the need of accomplishing higher education or undergoing professional certifications, some employers do value certifications.

Many Java professionals gain valuable experience from working on projects across a range of industries, meaning they learn about the needs of different sectors as well as how they work with developers. While some employers might value their employee more if they have a Java certification, because it adds value to the company, some employers may only value the number of years of experience a Java professional has.

With that being said, a Java certification included in your portfolio of skills certainly does not diminish your chances of getting hired. We have put together all you need to know for every Java certification which outlines the Java certification course and exam, each Java certification cost, and discuss whether a Java certification, in general, is necessary.


Oracle Java Certifications

There are four types of certification levels structured under the Oracle’s Java certification path. They are:

  • Oracle Certified Associate (OCA)
  • Oracle Certified Professional (OCP)
  • Oracle Certified Expert (OCE)
  • Oracle Certified Master (OCM)

The purpose of the Oracle Java Certification exams is to test your knowledge and capabilities on prospective jobs in the Java industry. To prepare and successfully pass the Java certification exams, you would require a satisfactory level of understanding of Java technologies. Nevertheless, you would also need to understand the exam pattern, type of questions you are going to be tested on and gain enough practice.

In this article, you will find relevant details of the different Java certifications under each level on the Java certification path. Each Java certification would have a multiple version of the same certification corresponding to the different Java SE or Java EE version.

How to prepare for a Java certification exam

How to prepare for a Java certification exam

Gaining a Java certification will require some time and preparation depending on your current circumstance. If you are a beginner and looking to improve your Java programming skills, then it is recommended that you spend at least three months preparing for the exam.

However, if your situation involves your employer requiring you to pass the exam quickly, then it is possible to pass the exam within a month—with the proper planning and preparation, of course.

It is best to plan and work out a structure that is best for you and your working capabilities. To focus on the Java certification exam, it is best to clear your calendar for the next few months to allow you to focus.

Next, you should consider purchasing a good book (or two) to do some background reading for the first few weeks. Most accredited Java certification books will include practice questions, and it is worth making notes while reading the book. Writing down the important points is a tried and testing revision tool and will help you remember the concepts. These can then be used for revising quickly just before the exam.

Here is a list of top rated books you should consider helping you prepare for your Java certification exam.

After spending time reading, it’s time to test your knowledge with real exam questions. There are a few popular online practice exam simulators that will allow you to test the real exam questions.

Two exam simulators; WhizLabs and Enthuware, are both dependable in the Java community. They are both up-to-date and high-quality test simulators you can purchase, and will both guarantee that you do well on the actual exams.

You can also purchase a mock simulator from Oracle Study, as well as try out the free mock exams.

You will know how prepared you are once you see the mock exam result, and if you are not scoring well enough, then you will have to improve your studying. If you can score more than 80% in the mock exam simulator, then you should be ready to take the Java certification exam.


 

How valuable is a Java certification and is it needed for a job?

How valuable is a java certification

According to the latest Pearson VUE survey, 88% of IT professionals recommend certification to a colleague when discussing a career or advancement in IT. While some IT professionals do an IT certification to keep up to date with the constant developments in the IT industry, other professionals do certifications to enhance their career prospects.

Oracle is situated in the top five certification programs, and 74% of these respondents would like to earn more specialised certifications. Some of the greatest certifications available are those that focus on a very specific technology or a subset of technologies, such as the Oracle Java certifications. By obtaining a niche IT certification and becoming skilled at one or two specific technologies, you will stand out in the marketplace against your peers.

Holding a Java certification could benefit your job prospects in the following ways:

  • A recruiter may select you for an interview among 100’s of other candidates of the same level of experience.
  • A Java certification is valid proof and recognition of your technical abilities.
  • While preparing for a Java certification exam, you truly understand learn Java concepts, therefore, it will support any technical tests you may have to do in a job interview.
  • You will have a great confidence boost knowing you have qualified Java skills.
  • The likelihood of better pay and better job prospect in the near future.

All in all, a Java certification will give you some credit (especially if you’re a junior who is just starting out). On the other hand, your professional value will not necessarily be favoured with or without a Java certification on its own. It is worth bearing in mind that a Java certification does not replace the need for a good personality, a strong mindset, and your physical ability to do the job.


Is a Java certification worth it, then?

Is a Java certification worth it

As long as Java programming exists, a Java certification is not obsolete. It may be the case that there are some companies that are not looking for Java certified professionals, but the demand for IT professionals is on the rise, therefore, a Java certification may offer you that competitive edge.

Gaining a Java certification from Oracle adds credibility to your CV/Resume, despite it not being exclusively necessary for some companies. Nevertheless, there is a lot to learn when preparing for a Java certification. As well, a Java certification takes a lot of time (and money) and should be thoroughly considered before deciding to complete one.

If you are starting out as a Java developer beginner, then having a Java certification may be very worthy and is something you can emphasise when applying for a job, since you will not have much work experience. Also, if you have a personal project and a Java certification, this gives a potential employer much more confidence in your abilities as opposed to having a personal but no Java certification.

Providing you have a strong technical ability to code, solve problems willingly, and have worked on significant Java product code bases before, a Java certification will simply validate your experience.
