• Prerequisites: Basic understanding of Java
• Taught by a Stanford-educated, ex-Googler, husband-wife team
• Please don't take this class if you have already signed up for our From 0 to 1: Learn Java Programming course (that includes a far longer and more in-depth version of this material)

This is a quick and handy course with exactly what you need to know (nothing more, nothing less!) about Object-Oriented programming in Java

Let’s parse that.

• The course is quick and handy: It explains object-oriented programming in Java in just the right level of detail for you to put these to work today.
• The course has exactly what you need - nothing more, nothing less. It starts from zero, builds up the design, then gives plenty of real-world examples, but crisply and quickly.
• The course is also quirky. The examples are irreverent. Lots of little touches: repetition, zooming out so we remember the big picture, active learning with plenty of quizzes. There’s also a peppy soundtrack, and art - all shown by studies to improve cognition and recall.

What's covered:

• The Object-Oriented Paradigm: Classes, Objects, Interfaces, Inheritance; how an OO mindset differs from a functional or imperative programming mindset;
• Mechanics: the mechanics of OO - access modifiers, dynamic dispatch, abstract base classes v interfaces.
• Principles: The underlying principles of OO: encapsulation, abstraction, polymorphism
• Interfaces, abstract base classes and interface default methods
• Packages and Jars: The plumbing is important to understand too.
• Language Features: Serialisation; why the Cloneable interface sucks; exception handling; the immutability of Strings;
• Types: the Object base class; the instanceof operator, primitive and object reference types; pass-by-value and pass-by-object-reference.
