NEW QUESTION # 101
A developer has the following requirements:
* Calculate the total amount on an Order.
* Calculate the line amount for each Line Item based on quantity selected and price.
* Move Line Items to a different Order if a Line Item is not in stock.
Which relationship implementation supports these requirements on its own?
- A. Line Item has a re-parentable master-detail field to Order.
- B. Order has are-parentable master-detail field to Line Item.
- C. Order has a re-parentable lookup field to Line Item.
- D. Line Item has a re-parentable lookup field to Order.
Answer: A
Explanation:
Why Re-Parentable Master-Detail Field?
A master-detail relationship allows Line Items to roll up totals (e.g., calculate total amount) to the Order.
Setting the relationship asre-parentablesupports moving Line Items between different Orders.
Why Not Other Options?
B). Lookup field: Does not support roll-up summary fields for calculations.
C and D: Relationships in the opposite direction (Order to Line Item) do not support the required logic.

NEW QUESTION # 104
A developer is implementing an Apex class for a financial system. Within the class, the variables 'creditAmount' and 'debtAmount' should not be able to change once a value is assigned. In which two ways can the developer declare the variables to ensure their value can only be assigned one time? Choose 2 answers
- A. Use the final keyword and assign its value in the class constructor.
- B. Use the static keyword and assign its value in a static initializer.
- C. Use the final keyword and assign its value when declaring the variable.
- D. Use the static keyword and assign its value in the class constructor.
Answer: A,C
Explanation:
To declare variables that cannot change once a value is assigned, the developer can use the final keyword, which means that the variable can only be assigned a value once, either when declaring the variable or inside a constructor1. For example:
Java
// Declare a final variable and assign its value when declaring
final Integer creditAmount = 1000;
// Declare a final variable and assign its value in the constructor
final Integer debtAmount;
public MyClass() {
debtAmount = 500;
}
AI-generated code. Review and use carefully. More info on FAQ.
The developer cannot use the static keyword to achieve the same effect, as static variables are not final by default. Static variables are used to store class-level information that is shared across all instances of the class, and they can be changed by any method in the class or by external classes2. For example:
Java
// Declare a static variable and assign its value in the class constructor static Integer creditAmount; public MyClass() { creditAmount = 1000;
}
// Declare a static variable and assign its value in a static initializer static Integer debtAmount; static { debtAmount = 500;
}
// Change the value of the static variables in a method
public void updateAmounts(Integer newCredit, Integer newDebt) {
creditAmount = newCredit;
debtAmount = newDebt;
}
AI-generated code. Review and use carefully. More info on FAQ.
