Can you please explain the difference between Abstract vs Encapsulation in other ways?

[Ashok_Murthy]

1. Why don’t we use regular class in place of abstract class and override the methods?
2. What exactly do you mean by “hides unnecessary data to simplify the structure.” ?
3. even using a regular class we can define a common behaviour. why do we need abstract class? for e.g partial method implementation still can be achieved using regular classes and overriding concept

Hello @Ashok_Murthy,

1. While regular classes and method overriding can achieve similar results, abstract classes offer a more formal and structured approach, particularly beneficial when designing a framework or a set of related classes with shared behaviors.

Hello @Ashok_Murthy,

2. “hiding unnecessary data to simplify the structure” means encapsulating the implementation details within a class, presenting a clean and straightforward interface to the outside world. This promotes code simplicity, and maintainability, and reduces the likelihood of errors.

Hello @Ashok_Murthy,

3. Regular classes with method overriding can achieve common behavior, abstract classes offer a more structured and explicit way to design class hierarchies, particularly when you want to enforce a specific structure or behavior across a group of related classes. It’s about choosing the right tool for the job based on the design requirements.
