What is class and example class?

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. But we can say Honda City having a reg. number 4654 is an ‘object’ that belongs to the class ‘car’.

A nested class is a member of its enclosing class . Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private. Static nested classes do not have access to other members of the enclosing class.

In Java, the class is a blueprint from which we can create an individual object . Java provides a keyword named class by which we can declare a class. Inside the class, we define class members and functions. It is not possible to create Java programs without class.
