Even though we now have Java 11 certification, I know many Java developers who are going for Java certification like Java SE 8 Programmer 1 and 2, also known as OCAJP 8 and OCPJP 8 with exam code 1Z0-808 and 1Z0-809. Even though Oracle split Java certification into 2 after acquiring Sun Microsystem in 2010, there is still confusion among Java developers whether they need to pass just one OCAJP exam or both OCAJP and OCPJP exam to become a certified Java developer. Well, The short answer is Yes, if you want to become a Java certified engineer then you need to pass both OCAJP and OCPJP, but the long answer depends upon your situation, e.g. whether you hold any previous Java certification or not, which we'll discuss in the second section.
