Certifications are commonly used to demonstrate mastery of a particular subject. People are more willing to gain certification for personal benefit and to exhibit their skills. According to recruitment agencies, the Java certification is perhaps the most sought-after credential for software developers.
Java certification puts you ahead of the pack for numerous Java-related employment openings.
There are several difficult Java questions in the certification exam. As a result, you'll be better prepared to answer challenging and difficult questions in job interviews than other candidates because you've been exposed to them before.
Last but not least, the abilities you obtain while studying for a certification will aid you in producing higher-quality and more stable software.
So here's your step-by-step guide for Java 8 Certification Preparation:
Preparing for any certification could be complicated and time-consuming if you don't follow a pragmatic roadmap. We've prepared this guide particularly for individuals like you who do things in a structural and a rational manner.
First and foremost, make an effort to obtain the most updated version of Java certificate. Since Java 8 is now the most recent version, begin with the Oracle Certified Associate, Java SE 8 Programmer certification. The test for this certification consists of questions on basic Java and object-oriented programming. The Oracle Certified Associate, Java SE 8 Programmer certification site has more specific information about this credential.
An Oracle Certified Associate, Java SE 8 Programmer credential is required for the Oracle Certified Professional, Java SE 8 Programmer test. This certification demonstrates advanced Java programming skills using JAVA SE APIs such as Concurrent API, JDBC API, and others.
There are a number of Oracle Certified Expert certifications available on a variety of subjects that need advanced Java knowledge. To apply for the Oracle Certified Expert, Java EE 6 Web Services Developer certification, for instance, you must first have the Oracle Certified Professional, Java SE 8 Programmer certification. The Oracle Certified Associate, Java SE 8 Programmer certification, on the other hand, follows a different route and does not need the Oracle Certified Associate, Java SE 8 Programmer certification.
The following are the steps to earning the Java EE Enterprise Architect certification:
Opt for one of the Oracle Academy Java courses
Pass Java EE 6 Enterprise Architect Certified Master 1Z0-807 exam
Pass Java (EE) Enterprise Architect Certified Master Assignment 1Z0-865 exam
Pass Java (EE) Enterprise Architect Certified Master Essay 1Z0-866 exam
You'll also need reliable books or study manuals, in addition to an online course, that completely cover the exam subjects or curriculum. So, depending on whatever exam you're going to take, get the certification book that corresponds to it.
This will allow you to concentrate on a single book and study for all exam subjects before fine-tuning your skills by studying blog posts or a more in-depth instruction on a specific topic.
Furthermore, the authors of these books provide their thoughts and experiences with certificates, which assists in exam preparation.
Some outstanding study guides for various Java certifications, such as OCAJP 8 and OCPJP 8, are listed below.

Writing code on a regular basis is one of the greatest strategies to start preparing for Java certification. Try coding the book's questions and examples to determine if the answer corresponds to the program's output.
Doing so will improve your coding skills, and also your code reading skills, which are critical for solving Java puzzles in real tests.
You can also play around with the script to discover how one minor change can completely alter the program's output. You won't learn anything if you merely complete exercises without coding.
It's the equivalent of students memorising concepts in school. Don't do that because even the tiniest alteration can cause the desired outcome to be thrown off. Click here to access a robust online Java compiler.
If you're familiar with Java 7 and wish to have a Java 8 certification on your portfolio, you can see which concepts are foreign to you. In contrast to the Oracle Certified Associate, Java SE 7 Programmer certification exam, the Oracle Certified Associate, Java SE 8 Programmer certification exam provides the following:
A new Date/Time API has been released.
Simple Lambda expressions for the Predicate interface
Interface Default and Static Methods
First, attempt to answer the practice questions, quizzes, fill-in-the-blanks, and other activities in your book or study manual honestly, as if you knew everything there is to know about them.
For example, once you've completed one question, you will understand what's expected of you, why the proper answer is correct, and why the other responses are incorrect.
You will understand a lot more principles by simply solving a specific question if you solve problems like this during your learning phase. This, in my opinion, is the most effective approach to use the activity and practise questions while also learning from them.
It is preferable to prepare by answering as many questions as possible that are identical to those that will be asked in the tests. Many developers recommend Enthuware as one of the best exam centres for Java certification. This test facility was very helpful in my preparation for something like the Oracle Certified Professional, Java SE 7 Programmer certification exam.
There is one starter test and six sample tests in the test centre for the Oracle Certified Associate Java SE 8 Programmer certification, and the last day exam is sufficient to achieve 90-100 points on the exam. In general, a real exam result would be 10 points higher than the sample exam score. The exam includes multiple choice questions in which participants must declare how many valid answers are available from a list of options. Nevertheless, be aware that the potential of more than one correct response makes the exam challenging.
You need an atmosphere to help you prepare in addition to strong study materials, and there is no better environment to get that ecosystem than http://coderanch.com/. It was earlier called the Javaranch forum, and it is without a doubt the finest place to go if you're studying for Java certifications.
The CodeRanch form contains the largest and most active group of Java developers studying for OCAJP, OCPJP, Java Web Developer Exam, Java Web Service Exam, and even the Java Architect level exam.
Several well-known authors, including Kathy Sierra and Mala Gupta, frequent the area. By contributing in this discussion, you will not only be informed about any changes to the syllabus, but also about other exam-related news.
Getting Java certified and acknowledged is beneficial to your education, career, and confidence in general, but it is especially vital for novices and freshmen Java developers who are just starting out. They are the ones who, in addition to their ordinary computer science degree, require something more to wow a potential employer and gain an advantage over other candidates.
The Java certification looks great on a CV. If you don't possess a first-class academic record or anything notable in your portfolio, go for the Java certification. This will bridge the gaps in your CV. It can also be used as a screening parameter. With 100 resumes from applicants and junior Java engineers, a hiring manager only has so much time to conduct interviews. He or she will almost certainly call the first ten people who have excellent academic achievements or Java accreditation on their resumes.
