Code-Alongs

Overview

Code-alongs are interactive coding sessions where you'll build projects alongside your instructors. These hands-on exercises will help you apply the concepts from your modules in a practical context.

What to Expect

  • Live, instructor-led coding sessions
  • Practical application of course concepts
  • Problem-solving strategies and best practices
  • Q&A opportunities with experienced developers

Code-Along 1: Single Source of Truth & Builder Pattern

In this code-along, you'll implement the Builder Pattern to create a configuration class for a web application. You'll learn how to handle complex object creation with many optional parameters while maintaining code readability.

What You'll Build

  • A configuration builder for a web application
  • Validation logic for required fields
  • Method chaining for fluent API design
  • Default values for optional parameters

Code-Along 2: Gradle & File I/O

In this code-along, you'll use Gradle to manage dependencies and build a Java application that performs file operations. You'll learn how to read, write, and process files efficiently.

What You'll Build

  • A Gradle project with proper dependency management
  • File readers and writers for various operations
  • Data processing from file inputs
  • Error handling for file operations

Preparing for Code-Alongs

To get the most out of your code-along sessions:

  1. Review the relevant module content beforehand
  2. Have your development environment ready
  3. Clone the starter repository when provided
  4. Prepare questions about aspects you're unsure of
  5. Be ready to type along - don't just watch!

After the Code-Along

To reinforce your learning:

  • Review the completed code and add comments
  • Try extending the project with additional features
  • Share your work with peers for feedback
  • Apply what you've learned to your sprint challenge
