Sprint Challenge

Challenge Requirements

• Implement the Builder pattern for object creation
• Create UML class and sequence diagrams
• Set up a Gradle project with dependencies
• Implement file I/O operations

Detailed Challenge Tasks

In this sprint challenge, you'll apply all the concepts you learned throughout the sprint:

1. Builder Pattern Implementation:
   • Create a WelcomeLetter class with multiple properties
   • Implement a Builder class inside the WelcomeLetter class
   • Add validation for required fields in the build() method
   • Create fluent interface methods that return the builder
2. UML Diagrams:
   • Create a class diagram showing your WelcomeLetter class structure
   • Include properties, methods, and access levels
   • Create a sequence diagram showing how objects interact
   • Show method calls, return types, and alternative cases
3. Gradle Setup:
   • Configure build.gradle with proper dependencies
   • Set up project structure correctly
   • Ensure tests can be run with Gradle
4. File I/O Implementation:
   • Read template data from files
   • Process data and generate output
   • Write results to output files
   • Handle exceptions properly
   • Close file resources correctly

Testing Your Implementation

Your solution will be tested against a series of unit tests that verify:

• The Builder pattern works correctly with both required and optional fields
• Your validation logic correctly detects missing required fields
• Your File I/O operations correctly read from and write to files
• Your implementation follows best practices for resource management
