Identifying prime numbers involves checking divisibility by integers up to the square root of the number.
A prime number is greater than 1 and has no divisors other than 1 and itself.
To check if a number n is prime, test divisibility from 2 to √n.
For example, to check if 29 is prime: test 2, 3, 4, 5 (all ≤ √29). None divide 29, so it's prime.
For composite numbers, like 30, it can be divided by 2, 3, 5, etc., confir...
Encapsulation is a fundamental OOP principle that restricts direct access to an object's data and methods.
Encapsulation helps in data hiding, protecting object integrity.
It allows controlled access through public methods (getters/setters).
Example: A class 'BankAccount' with private balance and public methods to deposit/withdraw.
Encapsulation promotes modularity and maintainability in code.
