In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods) .
Read moreWhat is the class and object in Java?
A class is a non-primitive or user-defined data type in Java, while an object is an instance of a class . A class is a basis upon which the entire Java is built because class defines the nature of an object.
Read moreWhat is class example in Java?
Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a “blueprint” for creating objects .
Read moreWhat is abstract class explain it with an example?
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.

Points to Remember
Read moreWhat is abstraction with example?
In simple terms, abstraction “displays” only the relevant attributes of objects and “hides” the unnecessary details . For example, when we are driving a car, we are only concerned about driving the car like start/stop the car, accelerate/ break, etc.
Read moreWhat is abstract class in C++ with example?
A class that contains a pure virtual function is known as an abstract class. In the above example, the class Shape is an abstract class. We cannot create objects of an abstract class. However, we can derive classes from them, and use their data members and member functions (except pure virtual functions).
