What this course does

This course provides a systematic, structured approach to Java fundamentals, with a strong focus on the Oracle Java 8 OCA (1Z0-808) certification.

It is ideal for:

• Beginners learning Java for the first time

• Developers returning to Java who want a solid foundation

• Anyone preparing for the OCA certification exam

  
  

All topics on Oracle’s official OCA syllabus are covered.

How you will learn

You will:

• Master core Java fundamentals step by step

• Get "under-the-hood" and understand why Java behaves the way it does — not just syntax

• Learn exam-critical rules and edge cases required for certification

• Reinforce concepts with assignments and MCQs

• Learn using whiteboards, diagrams, and memory visualisation

Where certification requires it, I clearly highlight rules and details you must remember — always with the reasoning explained first.

Course Overview:

This course takes a carefully structured approach to Java fundamentals and OCA preparation.

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

Assignments are included throughout to reinforce the theory.

OCA Certification Preparation

2 Full OCA Certification Tests

• 56 MCQs each (as per Oracle exam format)

• 2-hour time limit

• 65% pass mark (Oracle, April 2024)

  
  

15 OCA Practice Quizzes

• 248 MCQs in total

• Every question explained with a video solution

• Whiteboards and diagrams used extensively

These MCQs help you:

• Understand Java fundamentals at a deeper level

• Recognise common exam traps

• Build confidence for the 1Z0-808 exam

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.
