Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable . For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added.

An abstract class, in the context of Java, is a superclass that cannot be instantiated and is used to state or define general characteristics . An object cannot be formed from a Java abstract class; trying to instantiate an abstract class only produces a compiler error.

Read moreWhich is better interface or abstract class in Java?
Abstract classes should be used primarily for objects that are closely related, whereas interfaces are best suited for providing a common functionality to unrelated classes . Interfaces are a good choice when we think that the API will not change for a while.
Read moreWhat’s the difference between abstract class and interface?
The short answer: An abstract class allows you to create functionality that subclasses can implement or override. An interface only allows you to define functionality, not implement it . And whereas a class can extend only one abstract class, it can take advantage of multiple interfaces.
Read moreWhat are classes in programming?
In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming.
