Java is one of the most popular programming languages used for both the web and general backend development. No wonder expert Java programmers are in high demand. Oracle Java Programming Certification is not only a great way to prove your expertise to potential employers but also to improve your performance on the job.
Is Java Certification even worth it?
You will find two different opinions about certifications. Some deem them completely useless while others understand exactly what value they can add to your career. Here is our perspective.
Benefits of Java Certification
- Hones your craft — First of all, if you are trying to find out the dollar increment in your salary or are expecting a job offer after acquiring Java certification, then you are missing the point. The power of the certification is not in the certificate itself but in the learning involved when you prepare for the certification exam.
While studying for Java certification, you learn important techniques that you may not have used before. You learn the logic behind a lot the things that you normally do without knowing the reason. This gives you confidence about your craft and that confidence translates into better career prospects.
Thus, the biggest benefit of Java Certification is that you become better equipped to do your job well and thereby become more productive for your employer. - Builds a solid foundation — Secondly, many students and beginners do not know which topics are critical to learn for a solid foundation and that is why even after reading books and doing sample projects, they fail interviews. They lack the knowledge of what is really considered important. This is where certification helps.
Certifcation exam objectives are designed by experts at Oracle and include all the topics that one should master. Following a book that teaches all these objectives makes sure that you don’t miss out on important things, which will be required to know in interviews as well as on the job. - Shows commitment — Finally, certifications show the employer that you are committed towards learning new things within or outsite your area of expertise. Certifcations make your resume stand apart from all others who take no extra effort to master the technologies they are working with.
The bottom line is that nobody pays for mere degrees and certifications. But the Java Certification process provides a structured methodology to acquire useful skills, which is what the employers actually want. It is true that you will be using different libraries, which are not covered in certification exams, in your projects but no matter which library you use, the concepts that you learn while studying for the certification will be very helpful in making good use of the library.
