What is class object and instance?

A class is a blueprint which you use to create objects. An object is an instance of a class – it’s a concrete ‘thing’ that you made using a specific class. So, ‘object’ and ‘instance’ are the same thing, but the word ‘instance’ indicates the relationship of an object to its class.

What is object and instance in OOP?

An instance, in object-oriented programming (OOP), is a specific realization of any object. An object may be varied in a number of ways. Each realized variation of that object is an instance. In languages that create objects from classes, an object is an instantiation of a class.

What is the difference between a class and an instance of class?

1. What is the difference between a class and an instance of the class? A class describes a data type. An instance of a class is an object of the data type that exists in memory.

What is class and object in programming?

Object-Oriented Terminology class: a class describes the contents of the objects that belong to it: it describes an aggregate of data fields (called instance variables), and defines the operations (called methods). object: an object is an element (or instance) of a class; objects have the behaviors of their class.

What is called instance of class?

Each realized variation of that object is an instance of its class. That is, it is a member of a given class that has specified values rather than variables. An object is an instance of a class, and may be called a class instance or class object; instantiation is then also known as construction.

Why an object is called instance of a class?

A class can create objects of itself with different characteristics and common behaviour. So, we can say that an Object represents a specific state of the class. For these reasons, an Object is called an Instance of a Class.

What is an instance of a class?

What is a class and object explain with a real world example of class and object?

A class is a group of objects that share common properties and behavior. For example, we can consider a car as a class that has characteristics like steering wheels, seats, brakes, etc. And its behavior is mobility.

What is an instance in programming examples?

1. In programming, an instance is one occurrence of a class or object. For example, a program may have a class/object named Animal, but there could be many instances of Animal, such as lion, cat, and dog. In this case, all three instances (lion, cat, and dog) have the same number of legs, but make different sounds.
