This question runs in a pre-configured Salesforce environment - no personal connection required.
Create a method that returns a map where the key is an Account name and the value is a list of Contact full names for that account. Only include accounts from a specified industry. Use relationship queries to retrieve contacts associated with each account, and format each contact name as "FirstName LastName".
The method should accept one parameter: the industry to filter accounts. Return a map where account names are keys and lists of formatted contact names are values.
Method Signature
public static Map<String, List<String>> getContactsByAccountIndustry(String industry)
Examples
Example 1:
Input: industry = 'Technology'
Output: {'Tech Corp' => ['John Smith', 'Jane Doe'], 'Digital Solutions' => ['Bob Johnson']}

Example 2:
Input: industry = 'Healthcare'
Output: {'MedCare Systems' => ['Alice Brown'], 'Health Plus' => ['Charlie Davis', 'Diana Wilson']}
Explanation: Returns Healthcare accounts grouped with their contact full names
Example 3:
Input: industry = 'Manufacturing'
