Whiteboard-based explanations
Alongside IDE demonstrations, I make extensive use of whiteboards, particularly for:
Objects vs references
Call-by-value (primitives vs references)
String and wrapper immutability
Arrays
Inheritance (upcasting, downcasting, ClassCastException)
Garbage collection
These topics are often misunderstood — visual explanations make them click.
About the instructor
I am a University lecturer since 2002 and have been teaching Java certification syllabi (OCA and OCP) since 2013 on behalf of a highly regarded software company.
Graduates from my training programmes then sit the company’s own internal Java certification exam (similar in style to Oracle’s).
The pass rate has been 100% since year one.
I have co-authored two Java books:
Learn Java with Projects
Java Memory Management
I love teaching, and this course brings together:
My academic background
My industry experience
A passion for clear, structured explanations
A strong attention to detail — particularly suited to Oracle certification exams
Final note
This course is designed to give you:
A rock-solid foundation in Java
Confidence reading and writing Java code
Strong preparation for the Java 8 OCA (1Z0-808) exam
If you are new to Java — or want to truly understand the fundamentals while preparing for certification — this course is for you.
