QUESTION 5 OF 30

Have you ever experienced a problem or encountered issues when using Object-Oriented Programming (OOP?)

Questions like this can either stand on their own or be a follow-up to a previous question. During an interview, the interviewer will ask follow-up questions once you provide an answer. The reason for this is to explore a topic in more detail or confirm your knowledge of the topic. You should always be prepared for follow-up questions. Keeping your answers brief and to the point will encourage interviewers to ask follow-up questions and allow you to demonstrate your knowledge of the topic in more detail.

"While it is rare, I do occasionally encounter issues when using one of the object-oriented programming languages. These typically are due to an unavailable library or set of code that I need, or having to rewrite the code for the object I need for my program. These issues are easily overcome. By adding my new code for the library, the issue is not likely to be encountered twice."

Community answers are written by other candidates practicing this set. Reading how others frame the same question is one of the fastest ways to sharpen your own.

Anonymous Answer

When trying to reuse a class or import a class from a library, which is a subclass dependant on parent classes, it is necessary to run lots of extra code. The class you are trying to use comes with a whole unwanted 'environment.' Using inheritance can also be a problem if a parent or base class of a class you are using from a library is changed. This can break your code. The solution requires rewriting the code so that it works with the updated base class.
