NEW QUESTION # 131
A developer creates a new Apex trigger with a helper class, and writes a test class that only exercises 95% coverage of new Apex helper class.

NEW QUESTION # 132
Universal Containers (UC) wants to lower its shipping cost while making the shipping process more efficient.
The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to share a default pickup address. The developer is tasked to create the supporting object and relationship for this business requirement and uses the Setup Menu to create a custom object called "Global Address".
Which field should the developer add to create the most efficient model that supports the business need?

A. Add a master-detail field on the Account object to the Global Address object.
B. Add a master-detail field on the Global Address object to the Account object.
C. Add a lookup field on the Account object to the Global Address object.
D. Add a lookup field on the Global Address object to the Account object.

Answer: C

Explanation:
Why Lookup on Account to Global Address?
An Account can reference a single default Global Address via a lookup field, allowing multiple Accounts to share the same address.
This is more efficient than the reverse (lookup on Global Address to Account), as Global Address is the parent in this relationship.
Avoiding Master-Detail:
Lookup relationships provide flexibility in this use case since Accounts and Global Addresses have independent lifecycles.
Example:Create a custom lookup field on Account referencing the Global Address object.

NEW QUESTION # 133
A developer creates a custom exception as shown below:
public class ParityException extends Exception. {}
What are two ways the developer can fire the exception in Apex? Choose 2 answers

A. new parityException. ('parity does not match');
B. throw new ParityException() ;
C. throw new ParityException ('parity docs not match');
D. new ParityExcaption () ;

Answer: B,C

Explanation:
To fire an exception in Apex, the developer must use the throw statement along with an instance of the exception.
Option A: throw new ParityException();
Correct Way.
Creates a new instance of ParityException with no message and throws it.
Syntax is correct for throwing an exception.
Option C: throw new ParityException('parity does not match');
Correct Way.
Creates a new instance of ParityException with a custom message and throws it.
The exception class inherits from Exception, which allows passing a message to the constructor.
Options Not Correct:
Option B: new ParityException('parity does not match');
Incorrect.
This statement creates a new instance of ParityException but does not throw it.
Without the throw keyword, the exception is not fired.
Option D: new ParityException();
Incorrect.
Similar to Option B, this creates a new instance but does not throw it.
The exception will not affect the flow unless it is thrown.
Conclusion:
The two ways the developer can fire the exception are:
Option A: throw new ParityException();
Option C: throw new ParityException('parity does not match');
Both use the throw statement to fire the exception.
