Difference between OCAJP and OCPJP Certification Exams for Java Programmers

While java 7 certificationsing Spring Boot and Spring Cloud is sufficient for developing Microservices in Java, there is a couple of more advanced frameworks you can explore, like Eclipse’s Microprofile, Micronaut, and Quarkus. Without knowing these APIs, it would be very tough to write a Java application in 2023. Most of the libraries also now stop supporting versions lower than Java 8, which means you have to learn Java 8 features now than later. It’s already 5 years since Java 8 was released, so you literally have no excuse left. If you need more resources, you can also check out my earlier articles about the best design patterns books and courses to learn Object-Oriented Design patterns in depth. This is another common tech skill that every Java developer should learn as it will help you to troubleshoot backend issues. If you know SQL you can understand the stored procedure, query database, and find out whether the issue is in the Java layer or Database layer.

• The different exam has a different number of questions e.g. 1Z0-803 has 80 questions to be solved in 120 minutes while 1Z0-804 has 65 questions to be solved in 150 minutes.

As you can probably tell, there are lots of terms and elements to keep track of, and it can get overwhelming. Coding bootcamps and online courses are a great alternative that provide you with guided help to understand key concepts and the knowledge you need to become a Java developer. The Hibernate framework and the Hibernate Query Language are both very well-liked for mapping a territory object-oriented model to a relational database. Therefore, you will have a high possibility of being selected for the position of Java developer at any organization if you are familiar with these frameworks and can create projects using them.

This course is about the basics of multithreading and concurrent programming with some parallel concepts. In the 21st…

For example, they might need to work with the front-end development team to ensure that the user interface is consistent with the rest of the application. They should also be proficient in object-oriented programming, and they should have experience developing web applications and mobile apps. The work will depend on the level of experience (junior, mid-level, senior).

Spring Framework encourages writing clean code, which is easier to test and maintain by providing you with features like Dependency Injection and Inversion of Control. It also has a rich API for most of the day-to-day tasks, and that’s why every Java developer should learn the Spring framework. If you want to become a Java developer in 2023, I strongly recommend you to learn Spring Framework first. This is one of the most popular Java frameworks, and literally, almost every single Java application I have worked on in the last 5 years, uses this framework. If you need more resources, you can check out this list of courses to learn all new Java features in 2023. I know, it’s a lot of stuff, and that’s why I suggest you join an in-depth course like Java Concurrency in Practice bundle from Heinz Kabutz, a Java Champion, and authority when it comes to concurrency and design patterns.

Step 6. Focus on Continuously Improving Your Java Skills

Learn to design, develop, implement and maintain Java-based programs, components, and services. Integrate data with user interfaces to create business applications for every enterprise, from eCommerce to eLearning to all aspects of the Digital Transformation movement. The Oracle Corporation is responsible for the development of the Java platform and its Oracle Java courses are some of the best. Each of the java certification courses listed here comes from Oracle, and verifies a certain level of expertise and knowledge of Java, with respect to specific domains.

I would recommend, build a good project in Java before you apply. And a project can be anything from a calculator app with many features to a management system to a simple Tetris game. I have learned it this way in my journey to become a professional full-stack web developer. I am also OCJP Oracle Certified Java Programmer & OCJWCD Oracle Certified Java Web Component Developer. This includes things like understanding interfaces, what classes are? I know this as I am a professional Java programmer, & I’ve written code for production systems receiving millions of hits every single day.
