I have included 45+ (more coming) Oracle style multiple choice questions as part of the course. These come from the excellent Enthuware tool. Each question contains a video explaining the answer. This course started out as a Java 11 course (1Z0-819) and as a result many of the questions are from the Enthuware Java 11 question bank. However, I have removed the Java 11 specific questions and left only questions relating to Java 8 OCA. Note: I have not removed some questions which trivially use the “var” keyword (introduced in Java 10) – I have included a comment on these lines to explain the Java 8 equivalent, so that you can answer the question.
