What is encapsulation in OOP?

• Encapsulation is the mechanism of hiding internal details of an object and

exposing only necessary functionalities.

• It helps in protecting data and maintaining control over how it is accessed or

modified.

Example: A BankAccount class hides its balance and only allows deposit/withdraw

operations:

private decimal balance;
public void Deposit(decimal amount) { if(amount > 0) balance +=

mount; }
