Oracle Java Certification exams, which were earlier known as Sun Java Certification exams, are industry respected certifications in Java technology. There are several levels and categories of exams depending on the experience level of the candidate, namely - Junior Associate, Associate, Professional, Expert, and Master. The certifications that focus on Java programming are commonly known as OCAJP and OCPJP. Some people still call them by their old acronyms such as SCJP, SCP, OCJP, and OCP. The Java Expert level certifications focus on specific technologies such as EJBs, JPA, Web Components/Servlet/JSP, and Web Services. They are commonly known as OCE-EJB, OCE-JPA, OCE-WCD, and OCE-JWS.

As of 31st March 2019, Oracle has discontinued several certification exams. Most importantly, the Java EE 6 Certifications for EJB, JPA, Servlet/JSP, Web service exams have been discontinued.

Another important change is that for Java 11, the Oracle Certified Associate level for Java Programmer certification has been removed. Instead of upgrading the OCA Java 8 exam to OCA Java 11 exam, they have split the Professional level Java Developer certification into two parts - OCP Java SE 11 Programmer Certification Exam Part 1 (1Z0-815) and OCP Java SE 11 Programmer Certification Exam Part 2 (1Z0-816). So, you have to take two exams to get one OCP Java SE 11 Developer certificate.

Note that the experience level is not required by Oracle but is just a guideline.
