Abstraction and Interface Differance

Question

Accepted Answer

Abstraction focuses on hiding implementation details, while interface defines a contract for classes to follow.

Abstraction allows us to focus on the essential features of an object, while hiding unnecessary details.
Interface defines a set of methods that a class must implement, providing a contract for how the class should behave.
Abstraction is achieved through abstract classes and interfaces in object-oriented programming.
Abstraction helps in achieving code reusability and maintainability.
An example of abstraction is a car, where we don't need to know the internal workings to drive it.
An example of an interface is the Comparable interface in Java, which defines a method for comparing objects.

Accepted Answer

Abstraction contains Declaration and definition . Interface only contains Declaration Part. Multiple Inheritance is not achieved by Abstraction but In Interface, we can use multiple inheritances. Abstract class contains constructor and Interface does not have that. Static members are contained. The interface does not contain Static Members. A class can use only one Abstract Class. A Class can use multiple Interfaces.
