A. 0
B. 1
C. 2
D. 3

Answer: B

NEW QUESTION # 52
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?

A. Declare maxattempts as a member variable on the trigger definition.
B. Declare maxattempts as a variable on a helper class.
C. Declare maxAttempts as a private static variable on a helper class.
D. Declare maxattempts as a constant using the static and final keywords.

Answer: C

Explanation:
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?
