The issue is with declaring a static variable `defaultValue` with the generic type `E`. Static fields are shared among all instances of a class, regardless of the generic type parameter. Since the type parameter `E` can differ between different instances of `LinkedList`, a static field cannot be declared with a type parameter `E`.
