This question runs in a pre-configured Salesforce environment - no personal connection required.
Create a comprehensive JSON processor that fetches product data from DummyJSON API, processes the response, and returns structured information about products with error handling and data validation.
Your method should:
- Make an HTTP GET request to https://dummyjson.com/products
- Parse the JSON response
- Filter products with rating >= 4.0
- Return a Map with category as key and list of product titles as value
- Handle HTTP errors and JSON parsing errors gracefully
Examples:
Input: Successful API call to DummyJSON products endpoint
Output: Map<String, List<String>> grouped by category with high-rated products
Explanation: Returns products with rating >= 4.0 grouped by category
Input: API endpoint is unreachable
Output: Empty map
Explanation: Error handling returns empty result
