How can we ensure a method is not overridden by a subclass?   a. Making a method private will make it so the subclass cannot see the method, and it will not be able to override it and change its functionality. b. The protected keyword will protect the method from being overridden. c. The purpose of inheritance is to allow a sub-class to change any implementation of the parent class, so we cannot stop a method from being overridden. d. If the method does not appear in the interface we implement, the sub-class will not override it.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
