Working with Java Data Types – primitives, wrappers, operators, String immutability, StringBuilder
Controlling Program Flow – conditional (if/switch), loops (while/do-while/for), break, continue.
Working with Methods and Encapsulation – static, constructors, access modifiers, call-by-value.
Java Object Oriented Approach – inheritance, overloading/overriding, polymorphism, abstract, constructors, upcasting/downcasting, interfaces, enums, instanceof
Exception Handling – try/catch/finally, try-with-resources, suppressing exceptions, exception signatures and inheritance, custom exceptions
Arrays – declaring, initialising, anonymous arrays, reference assignments, 2D arrays, arrays with wrappers
Working with Selected classes from the Java API – ArrayLists, Lamba expressions, Predicate Lambdas, Calendar Data manipulation

No.
Description:
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.
Topics include:
Java Basics
Working with Java Data Types
Controlling Program Flow
Working with Methods and Encapsulation
Java Object Oriented Approach
Exception Handling
Arrays
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
Arrays
Inheritance – upcasting, downcasting, ClassCastExceptions (why they occur)
Garbage collection
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.
Who this course is for:
Beginner Java developers interested in learning the fundamentals with the help of diagrams.
Anyone interested in getting the Java 8 Oracle 1Z0-808 (OCA) Certification exam.
