Learning Objectives
6 objectives- Understand and explain the core principles and concepts of object-oriented programming (OOP).
- Define and implement classes and objects, including encapsulation and abstraction techniques.
- Apply inheritance and polymorphism to create hierarchical and flexible class structures.
- Analyze and design relationships between classes using association, aggregation, and composition.
- Use design principles and patterns to build maintainable, scalable, and robust OOP systems.
- Implement exception handling to manage errors effectively in object-oriented programs.
Content Outline
PreviewUnit 613: Object-Oriented Programming Fundamentals and Design
1. Introduction to Object-Oriented Programming
- Overview of OOP
- Key principles: Classes, Objects, Encapsulation, Inheritance, Polymorphism
- Benefits of OOP: Modularity, reusability, scalability
2. Classes and Objects
- Definition of Classes as Blueprints
- Creating and Instantiating Objects
- Properties (Attributes) and Methods (Behaviors)
- Access modifiers and visibility (public, private, protected)
- Constructors and Destructors
3. Encapsulation and Abstraction
- Encapsulation:
- Data Hiding and Protection
- Getters and Setters
- Abstraction:
- Focusing on Essential Attributes and Behaviors
- Abstract Classes and Interfaces (Conceptual overview)
4. Inheritance and Polymorphism
- Inheritance:
- Base and Derived Classes
- Overriding and Extending Behavior
- Use of super/parent keyword
- Polymorphism:
- Compile-time (Method Overloading)
- Runtime (Method Overriding)
- Dynamic Binding
5. Relationships Between Classes
- Association:
- Definition and Examples
- Aggregation:
- Has-a Relationship
- Lifespan independence
- Composition:
- Strong Ownership Relationship
- Lifespan dependency
- Implications for design and maintenance
6. Method Overloading and Overriding
- Method Overloading:
- Defining Multiple Methods with Same Name but Different Parameters
- Use Cases and Benefits
- Method Overriding:
- Redefining Methods in Subclasses
- Rules and Best Practices
7. Design Principles in Object-Oriented Programming
- Introduction to SOLID Principles:
- Single Responsibility Principle (SRP)
- Open/Closed Principle (OCP)
- Liskov Substitution Principle (LSP)
- Interface Segregation Principle (ISP)
- Dependency Inversion Principle (DIP)
- Applying SOLID for maintainable and scalable code
8. Design Patterns
- Introduction to Design Patterns
- Common Patterns:
- Singleton Pattern
- Factory Pattern
- Observer Pattern
- Strategy Pattern
- Practical examples and use cases
9. Exception Handling in Object-Oriented Programming
- Understanding Exceptions and Errors
- Try-Catch-Finally Blocks
- Throwing Exceptions
- Creating Custom Exception Classes
- Best Practices for Error Handling
