In Java programming, nested and inner classes often go hand in hand. A class that is defined within another class is called a nested class. An inner class, on the other hand, is a non-static type, a particular specimen of a nested class.6 Mar 2017

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.17 Şub 2022

There are four types of inner classes: member, static member, local, and anonymous . A member class is defined at the top level of the class.
Read moreWhat are nested and inner classes in Java?
A non-static nested class is a class within another class . It has access to members of the enclosing class (outer class). It is commonly known as inner class . Since the inner class exists within the outer class, you must instantiate the outer class first, in order to instantiate the inner class.
Read moreWhat is the main use of inner classes?
We use inner classes to logically group classes and interfaces in one place to be more readable and maintainable . Additionally, it can access all the members of the outer class, including private data members and methods.
Read moreWhy do we need inner class in Java?
Inner classes are a security mechanism in Java . We know a class cannot be associated with the access modifier private, but if we have the class as a member of other class, then the inner class can be made private. And this is also used to access the private members of a class.8 Oca 2018
Read moreWhen Should inner classes be used?
Use a non-static nested class (or inner class) if you require access to an enclosing instance’s non-public fields and methods . Use a static nested class if you don’t require this access.
