OOP Interview Questions and Answers
Question - 91 : - What is meant by Garbage Collection in OOPs world?
Answer - 91 : -
Object-oriented programming revolves around entities like objects. Each object consumes memory and there can be multiple objects of a class. So if these objects and their memories are not handled properly, then it might lead to certain memory-related errors and the system might fail.
Garbage collection refers to this mechanism of handling the memory in the program. Through garbage collection, the unwanted memory is freed up by removing the objects that are no longer needed.
Question - 92 : - Can we run a Java application without implementing the OOPs concept?
Answer - 92 : -
No. Java applications are based on Object-oriented programming models or OOPs concept, and hence they cannot be implemented without it.
However, on the other hand, C++ can be implemented without OOPs, as it also supports the C-like structural programming model.
