when a class is defined within another class then such a class is called a nested class. Nested classes are a feature of Java that is included in jdk1.1.
The reasons of why we use nested classes are:
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.

class OuterClass {

...

static class StaticNestedClass {

...

}

class InnerClass {

...

}

}
