Perks of having OCP: Java SE 17 Developer

Hiring Preferences

Many government organisations and consulting firms that work on government projects place a high value on Java certification. Not every job requires Java certification, but there are very few jobs that prefer a certified Java developer over an uncertified one.

A beginner's chances of getting called from these companies improve after passing a Java certification like OCAJP or OCPJP with high marks.

You can check out the Job Openings especially for JAVA SE 17 ORACLE CERTIFIED PROFESSIONALS via this link

 

Add value to Resume

Java certification looks great on a resume. Go for Java certification, especially if you don't have outstanding academic records or anything extracurricular that stands out.

This will fill any gaps in your resume. It can also be used as a filtering criterion.

 

Better Increment in Salary

 

One reason for this could be that employers value Java Certified professionals more than non-certified professionals. True, some companies specifically state that they will only hire Oracle Certified Professionals.

One reason for this is that they save time and money by using online Java testing sites such as Brainbench, which is used by hiring managers to test Java fundamentals.

Another reason for a better package for certified Java professionals is the confidence and bargaining power they gained by performing well in Java certification.
 

Reimbursement from Employer

Another reason to get Java certified is to advance your position on the team. Many people have reported that passing the SCJP in the past and the OCPJP today with a good score improves your impression in the organisation.

People now recognise your Java skill more than ever before and hold you in high regard.

Frequently asked questions

Is it difficult to crack Java SE 17 Developer Oracle Certification exam?

Oracle's Java Certification has a tough passing percentage, close to 68% for OCPJP (the Oracle Certified Professional Java Programmer). So, it is relatively tough, but with strategic preparation, one can easily pass the exam with flying colors.

Does preparing for OCPJP and OCAJP the same?

Preparing for OCPJP is similar to preparing for OCAJP, but you must use OCPJP-specific resources. You should also go over more topics in greater depth because OCPJP is a difficult nut to crack.

How to upgrade the speed and accuracy?

Since practice makes perfect, try to solve as many as you can. You will gradually improve your speed and accuracy for the exam.
