The Java Collection Framework includes the AbstractSequential List class, which implements the Collection interface, and the AbstractCollection class. It is used to implement an unmodifiable list, for which one needs to only extend this AbstractList Class and implement only the get() and the size() methods.

AbstractSequential List Method:
add(int index, E element)Inserts the specified element into this list at the specified position (optional operation).
addAll(int index, Collection c)Inserts all the elements from the specified collection at the specified position into this list (optional operation).
get(int index)The element at the specified position in this list is returned.
iterator()Iterates through the elements in this list (in proper sequence).
listIterator(int index)Returns a list iterator over the list’s elements (in proper sequence).
remove(int index)The element at the specified position in this list is removed (optional operation).
set(int index, E element)Replaces the element at the specified position in this list with the specified element (optional operation).

		// Creating an empty AbstractSequentialList
			abs = new LinkedList<String>();

		// Using add() method to
		// add elements in the list
      abs.add("Home Decor");

		// Output the list
		System.out.println("AbstractSequentialList: "
						+ abs);

		// Remove the head using remove()

		// Print the final list
		System.out.println("Final List: "
						+ abs);

		// Fetching the specific
		// element from the list
		// using get() method
		System.out.println("The element is: "
						+ abs.get(2));
AbstractSequentialList: [Accessories, Home Decor, Books, Stationery, Appliances, Toys]
