The reason why inner classes cannot have static members is because static members are usually instantiated when the program starts . However, an inner class depends on having an instance of its enclosing class in order to create it and then access it’s members.

If you declared a class type definition as static anywhere (nested or not nested), you’d get a compiler warning and it will be stripped off. Classes cannot have storage class specifiers and static has been repurposed something different inside a class .

In the Java programming language, the keyword static means that the particular member belongs to a type itself, rather than to an instance of that type . This means we’ll create only one instance of that static member that is shared across all instances of the class.24 Kas 2021

Static Nested Class : can’t access enclosing class instance and invoke methods on it, so should be used when the nested class doesn’t require access to an instance of the enclosing class . A common use of static nested class is to implement a components of the outer object .15 Kas 2011
Read moreWhat is the advantage of static inner class?
The advantage of a static nested class is that it doesn’t need an object of the containing class to work . This can help you to reduce the number of objects your application creates at runtime. It’s called a nested class. All nested classes are implicitly static; if they are not static they are called inner classes.

Inner classes cannot declare static members other than compile-time constants .
Read moreWhat is the difference between inner class and static inner 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.
