How to check whether a given integer is prime number or not ?
This is the complete solution to check whether a given integer number is prime or not. This solution is designed to to solve the problem using an interface, super class and four derived classes implementing the interface. The core logic is to check the divisibility of the given number, from 2 to till the square…
