Implementation of Lists

This lecture focuses on the implementation of collections, specifically lists, in Java. The instructor explains the hierarchy used to implement simplified versions of Java lists, covering methods like size, add, remove, contains, get, set, and iterator. The lecture also delves into the abstract class S abstract list, which implements the S list interface and discusses methods like ISMT, Contains, and ToString. Additionally, the instructor introduces protected methods for validating indexes and prepares for writing concrete implementations of S array list and S linked list.
