最新的 Salesforce Developers CRT-450 免費考試真題 (Q187-Q192):

問題 #187

Which tool should be used to implement this requirement?

A. Process Builder
B. Apex trigger
C. Lightning Component
D. Lightning

問題 #188
A developer must create a CreditcardPayment class that provides an implementation of an existing Payment class. Public virtual class Payment { public virtual void makePayment(Decimal amount) { /*implementation*/
} } Which is the correct implementation?

A. Public class CreditCardPayment implements Payment {
public virtual void makePayment(Decimal amount) { /*implementation*/ }
}
B. Public class CreditCardPayment implements Payment {
public override void makePayment(Decimal amount) { /*Implementation*/ }
}
C. Public class CreditCardPayment extends Payment {
public virtual void makePayment(Decimal amount) { /*implementation*/ }
}
D. Public class CreditcardPayment extends Payment {
public override void makePayment(Decimal amount) { /*implementation*/ }
}

答案：D

解題說明：
To create a CreditcardPayment class that provides an implementation of an existing Payment class, the developer should use the extends keyword to indicate that CreditcardPayment is a subclass of Payment, and the override keyword to indicate that CreditcardPayment provides a different implementation of the makePayment method than the superclass. This way, the CreditcardPayment class inherits the properties and methods of the Payment class, but can also modify or add its own behavior.
The other options are not correct because:
* B. Public class CreditCardPayment implements Payment. This option is not valid, because the implements keyword is used to indicate that a class implements an interface, not another class. An interface is a collection of abstract methods that a class must define, but a class is a blueprint for creating objects that have properties and methods.
* C. Public class CreditCardPayment extends Payment. This option is not valid, because it does not use the override keyword to provide a different implementation of the makePayment method. Without the override keyword, the subclass would inherit the same implementation of the method as the superclass, which defeats the purpose of creating a subclass.
* D. Public class CreditCardPayment implements Payment. This option is not valid, because it has the same problem as option B. It uses the implements keyword instead of the extends keyword, which is incorrect for creating a subclass of another class.

* : Inheritance
* : Interfaces
