Java certifications to pursue
There are typically five certification levels under Oracle's Java certification path. They are:
Oracle Certified Junior Associate (OCJA)
The novice-level Java Foundations Certified Junior Associate certification is for secondary school, college, or university students studying computer science or taking part in the Oracle academy training. This certification can help validate a student's capabilities and show their willingness to learn more about Java. It's typically not necessary to have hands-on professional experience with Java to earn this certification. A basic understanding of the Java programming language, analytical problem-solving skills, and an interest in gaining experience can be helpful in earning the OCJA certification.
Oracle Certified Associate (OCA)
The Java associate certifications test your knowledge of the fundamentals of Java, such as working with Java data types, Java basics, and the use of operators and decision constructs. The exam also assesses your knowledge of creating and using arrays and loop constructs, working with methods, encapsulation, and inheritance, and handling expectations. Other levels of this associate certification, such as the OCA Java SE 8 Programmer certification, are for candidates with a technical background looking to advance their knowledge. You can also pursue an OCA certificate as a Java SE 5, 6, or 7 Programmer to further demonstrate your expertise.
Oracle Certified Professional (OCP)
This certification is typically for developers with advanced skills and expertise in the Java programming language. These professionals strive to earn this certification to advance their careers and develop their knowledge of, and proficiency in, Java technologies. OCP certifications typically attest that you understand Java's structure and basic syntax, object-oriented concepts, flow control, declarations, initialization and scoping, and fundamentals. It isn't necessary to be a certified Java associate to take this exam. Java SE professional certifications include:

How to get a Java certification
The steps to earning a Java certification include:
1. Decide on a certification
There are different types and levels of certification from which you can choose. Depending on your knowledge of the Java programming language, your options may range from a junior associate certification to an expert-level certification. You can research available certifications to select the one that fits your current skill level. For example, if you're a beginner looking to start a career as a programmer, you can consider earning a junior associate certification. If you've been in the programming field for a while and you're considering advancing your career, a master's or expert certification can be beneficial.
2. Attend classes
Taking classes or attending programs specific to the certification you intend to earn can help you pass the certification exams. You can either take classes online or in-person. Completing courses to earn a Java certification may not be mandatory, but it can teach you the field's most critical skills and help prepare you for a career in Java programming.
3. Register and prepare for the exam
You can register for your certification exam after taking classes and preparing. It's possible to buy an exam voucher and schedule your test for a convenient date. As the exam vouchers expire after six months, it's essential that you schedule your exam within that time frame, especially as certain certifications require you to complete multiple exams. Some programs offer study guides to their exams, but you can also find study questions and practise exams online.
As each exam covers different topics, it can be helpful to focus your studies on the particular exam for which you're preparing. You can continue earning more certifications to enhance your resume and increase your job security.
