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.

Java inner class or nested class is a class that is declared inside the class or interface . 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.

The derived class (the class that is derived from another class) is called a subclass. … So, as you drop down in the hierarchy, the classes become more and more specialized: Definition: A subclass is a class that derives from another class. A subclass inherits state and behavior from all of its ancestors .

In the Java language, classes can be derived from other classes, thereby inheriting fields and methods from those classes. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class).
Read moreWhat is the difference between a nested class and an inner class in Java?
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.
Read moreWhat is the difference between an inner class and a static nested class?
1) First and most important difference between Inner class and nested static class is that Inner class require instance of outer class for initialization and they are always associated with instance of enclosing class. On the other hand nested static class is not associated with any instance of enclosing class.
Read moreIs nested class the same as inner class?
Non-static nested classes are called inner classes . Nested classes that are declared static are called static nested classes. 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.
