Because head is an attribute of the LinkedList class

Nope, but you're welcome to move the field afterwards

Java inner class and static nested class

1) Head is defined outside of the inner class because the inner class does not need a "Head" field, but the outer class does.

2) No, it doesn't.

3) As the comment says, it is defined as static so that main() can access it.
