A developer has an integer variable called maxAttempts. The developer needs to ensure that once maxAttempts is initialized, it preserves its value for the length of the Apex transaction; while being able to share the variable's state between trigger executions. How should the developer declare maxAttempts to meet these requirements?
Correct Answer: D
To preserve the value ofmaxAttemptsfor the length of the Apex transaction and share its state between trigger executions: Static Variable: Static variables are initialized once per transaction and retain their value throughout the transaction. They can be accessed without instantiating the class. Private Scope: Declaring it as private ensures encapsulation and prevents unintended external modification. Helper Class: Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices. Example Code:public class HelperClass { private static Integer maxAttempts = 5; // Default value public static Integer getMaxAttempts() { return maxAttempts; } public static void setMaxAttempts(Integer attempts) { maxAttempts = attempts; } } A:Constants (static + final) cannot be modified after initialization. B:Trigger member variables cannot retain values across executions within the same transaction. C:Declaring it as a non-static variable in a helper class would reset its value during each trigger execution. Why Not the Other Options?
