Code-Alongs
About Code-Alongs
Welcome to the Code-Alongs section of BD Unit 3 Sprint 9. These interactive coding sessions are designed to help you apply the concepts you've learned in real-world programming scenarios.
What to Expect
During these code-along sessions, you'll work alongside instructors to implement advanced Java concepts including design patterns, OOP principles, exception handling, and testing techniques. These exercises provide hands-on practice and reinforce the theoretical concepts covered in the modules.
Design Patterns Code-Along
Implement common design patterns including Factory Method, Singleton, and Observer in a real-world application context.
What You'll Build
An event notification system that demonstrates several design patterns working together.
Key Concepts
- Factory Method pattern for creating different event types
- Observer pattern for event notification
- Singleton pattern for a centralized event manager
Advanced OOP Code-Along
Work with inheritance, polymorphism, and composition to build a flexible and maintainable application structure.
What You'll Build
A content management system with various content types and formatting options.
Key Concepts
- Inheritance hierarchies for content types
- Polymorphic methods for content processing
- Composition for formatter objects
- SOLID principles in practice
Exception Handling Code-Along
Create robust error handling strategies for a Java application dealing with various failure scenarios.
What You'll Build
A file processing utility with comprehensive exception handling.
Key Concepts
- Custom exception hierarchies
- Try-with-resources for resource management
- Exception chaining for context preservation
- Exception handling strategies for different application layers
Testing and Debugging Code-Along
Master test-driven development and debugging techniques with a practical coding session.
What You'll Build
An inventory management system developed using TDD principles.
Key Concepts
- Unit testing with JUnit 5
- Mocking with Mockito
- Test-driven development workflow
- Debugging techniques for complex bugs
- Remote debugging scenarios
