Mastering Critical Core Java SE 8 OCA (1Z0-808) Concepts
This course is a systematic approach to the Oracle Java 8 1Z0-808 (OCA) Certification exam. All of the topics on the syllabus on Oracles website are covered.
Working with Java Data Types
Controlling Program Flow
Working with Methods and Encapsulation
Java Object Oriented Approach
Working with Selected classes from the Java API
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.
As well as using an IDE to explain concepts, I use a whiteboard wherever I can. I find it an excellent learning tool; particularly around the topics of:
Java objects versus references
String and wrapper-class immutability
Inheritance - upcasting, downcasting, ClassCastExceptions (why they occur)
I am a lecturer since 2002 and I have taught the OCA (and OCP) syllabus since 2013 on behalf of a highly regarded software company. On completion of my training, graduates then face the company's own internal Java Certification exam (similar in style to Oracle's). I have no visibility into the questions they will face. It is a 3 hour long intensive exam. The company are delighted with the pass rate (100% since year 1).
I love teaching and this course has all my experience in explaining the critical fundamental concepts of Java. In addition, I have a strong attention to detail which lends itself perfectly to the Oracle Java Certification exams. I am delighted that Enthuware, in their explanations, have linked to my YouTube channel.
