What is the Key Difference Between Static and Inner Classes in Java?

Static vs. Inner Classes in Java

Non-static nested classes are defined within another class but are not static. They have access to the members of the class within which they are nested.

On the other hand, static nested classes are defined within another class but are declared static. They do not have a reference to the nesting instance and cannot access non-static members of the containing class.

The key difference between static and inner classes lies in their access to the enclosing class's instance members. Inner classes have full access to non-static members, while static nested classes do not.
