Is it correct to use a method that is not currently created?

Question

OOP

1. There is an abstract class that implements some logic (sendRequest), declares an abstract method (sendHttp) and calls it.
2. This abstract method will be defined in the child class. And the sendRequest method will be called.
This is implemented in the backend part of the application.
Is this method definition correct, if not, what is the appropriate variant for this?

Answer 1

Yes it is quite normal approach from the point of view of OOP. If you provided the code, it would be possible to give a more detailed comment.
