Hi Friend,

When a class is defined within another class then such a class is called a nested class.

Inner class is a non static class declared inside another class.Non-static inner class keep the reference of outer class and allow to access member variable of outer class. It helps in defining an interface of a class.

We use nested classes because of the following reasons:

It is a way of logically grouping classes that are only used in one place.

It increases encapsulation.Nested classes can lead to more readable and maintainable code.
