Fundamental OO Concepts

Introduction

Software development is a mental activity. Both Object-Oriented (OO) Design and Programming require you to think clearly about your mental models of software. Design is about modeling software components and the Unified Modeling Language (UML) is the tool of choice when drawing software models. This lesson reinforces OOD and OOP techniques you learned in your first year and provides additional context that ties all three aspects (mental model, design model and Java code) together.

Learning Outcomes

• Recognize and describe core OO characteristics
• Create UML notation that models the core OO characteristics
• Create Java code that implements the core OO characteristics
