Developed new search and detail scenarios for the Car Rental API demo within the ExpediaGroup/xap-java-sdk repository, expanding the demo’s feature coverage and improving its utility for both onboarding and customer adoption. Leveraged Java to implement end-to-end examples that demonstrate searching car listings and retrieving detailed car information using offer tokens, integrating these scenarios into the main demo runner for a seamless workflow. Updated the README documentation to clearly outline usage patterns and scenario instructions, supporting faster developer ramp-up. Focused on API integration and SDK example quality, the work enhanced demonstration fidelity and maintainability without introducing new bugs during the period.
