OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide is a certification-preparation manual by Jeanne Boyarsky and Scott Selikoff for Oracle exam 1Z0-808. Published in the Sybex Study Guide series, it combines a structured introduction to Java programming with preparation for an exam that tests close reading of source code, compiler behavior, and language rules. Its scope includes foundational syntax, control flow, methods, object-oriented design, exceptions, common library classes, and Java 8 additions such as lambda expressions and the date and time API. Rather than treating Java as a list of definitions, the guide is organized around the practical distinctions that determine whether code compiles, runs, throws an exception, or produces an unexpected result. Assessment material is integral to the format: readers encounter exercises, chapter reviews, and practice-oriented questions alongside explanations. Although aligned to a Java SE 8 certification whose original exam context is historical, the book remains a concentrated reference for learning the semantics and core idioms of pre-module Java.
