Difference between static nested class and regular class

Question

I know this is a bit of a duplicate question but I want to ask it in a very specific way in order to clarify a very important point. The primary question being: Is there any

Answer 1

A subtle difference is that a nested class has the ability to shadow members of the enclosing type:

class ContainingClass {
    public static String privateStaticField = "a";

    static class ContainedStaticClass {
        public static String privateStaticField = "b";
        public static void main(String[] args) {
            System.out.println(privateStaticField);  // prints b
        }
    }
}

But that's also related to the scope of the class.
