In Java, as in other object-oriented programming languages, classes can be derived from other classes. The derived class (the class that is derived from another class) is called a subclass . The class from which its derived is called the superclass. In fact, in Java, all classes must be derived from some class.

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.

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.
