Abstract Class

An abstract class is a blueprint for other classes. It defines common properties and methods that multiple related classes share, but it itself cannot be instantiated into an object. Think of it as a template that specifies what features a group of classes should have, but leaves some details to be implemented by the specific classes. This helps organize code better, promotes code reuse, and ensures consistency across related classes. For example, an abstract class "Vehicle" might define methods like "move," but each specific vehicle (like car or bike) would implement the details differently.
