Can you explain the concept of abstraction in object-oriented programming?

Abstraction in object-oriented programming is a principle that allows hiding complex implementation details and showing only the necessary interface for interacting with an object. This helps focus on what the object does, rather than how it does it.

For example, when working with a Car class, we can use methods like start(), drive(), without delving into the details of the engine or transmission operation. The internal mechanisms are hidden, which simplifies the use and maintenance of the code.
