About

The Oracle Certified Associate, Java SE 8 Programmer I (OCA) is the foundational certification for Java developers. It validates your ability to write, test, debug, and understand Java code using Java SE 8 features, including functional programming constructs introduced with Java 8. This is the first of two exams required to achieve the Oracle Certified Professional (OCP) Java SE 8 Programmer II designation. The cert was released in 2014 with Java 8 and remains current as of 2026, though Oracle has modernized the exam format (reduced from 70 questions/150 minutes to 56 questions/120 minutes as of September 2022).
