[Solved] concrete LinkedList class

Create concrete LinkedList class that extends the provided ALinkedList class. You will need to override the extractmethod in your class. You can use your main method for testing your method (although you do not need to provide a main method).concrete LinkedList class that extends the provided ALinkedList class.

Recall that a list is an ordered collection of data

X_0, X_1, X_2, ..., X_n

The extract(int start, int end) method removes all elements

X_start, X_start_1, ..., X_end-1

from the list. It also returns all removed elements as a new list (LinkedList) that retains the same ordering.

For example, if the initial list called animals was

cat, dog, eel, cow, owl, pig, pip

then animals.extract(1,5) would return the new list

dog, eel, cow, owl

and animals would now be the list

cat, pig, pip
