Advanced OOP - Reference Handout
What You'll Learn Today
Today we'll explore advanced Object-Oriented Programming concepts in Java. You'll learn about inheritance, interfaces, polymorphism, and basic design patterns. We'll apply these concepts in a mini-project to solidify your understanding.
Key Concepts
Inheritance
- Extending classes
- The
extends
keyword - Method overriding
- The
super
keyword - Types of inheritance
Interfaces
- Creating and implementing interfaces
- The
implements
keyword - Default methods
- Multiple interface implementation
- When to use interfaces vs inheritance
Polymorphism
- Method overriding vs overloading
- Runtime polymorphism
- Type casting
- instanceof operator
- Abstract methods and classes
Basic Design Patterns
- Singleton pattern
- Factory pattern
- Observer pattern
- Strategy pattern
- When to use each pattern
Mini-Project: Animal Kingdom Simulator
Create a simple simulation with: - Base Animal class - Different animal types (inheritance) - Behavior interfaces - Polymorphic method calls - At least one design pattern
Project Requirements
- Create hierarchy of animal classes
- Implement movement and sound interfaces
- Use polymorphism for animal behaviors
- Apply a design pattern of your choice
- Add simple documentation
Additional Resources
- Java Documentation on Inheritance
- Design Patterns reference
- Online Java Visualizer
- Sample code and solutions
Notes
- Focus on understanding the concepts
- Ask questions about real-world applications
- Take breaks when needed
- Keep your code clean and organized
- Document your design decisions
