What is a class in oops?

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.

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) .

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 .
