Although you may have a theoretical understanding of Object-Oriented Programming (OOP) concepts, many individuals often struggle to articulate these concepts when prompted by an interviewer. Fundamentally, the purpose of coding is to address real-world problems. In Object-Oriented Programming (OOP), the logic is structured around the concept of objects, incorporating key principles such as abstraction, encapsulation, inheritance, and polymorphism. Consider various real-world entities like cars, bikes, ATMs, and coffee machines, each with different brands and names. In OOP, these entities are referred to as objects. The logic for objects is implemented through classes. For instance, a phone class may include functionalities like making calls, Bluetooth connectivity, and taking photos. Each of these functionalities is organized into classes. When creating classes, it's crucial to consider the SOLID principles, ensuring a robust and maintainable code structure.
