In this lesson, students will learn about the ArrayList, LinkedList, HashSet, and TreeSet classes in Java, which are concrete implementations of the List, Set interfaces, respectively. The following topics will be covered:
ArrayList class: An in-depth explanation of the ArrayList class, including its constructor, methods, and use cases. Students will learn about how ArrayList works under the hood, how to add and remove elements, and how to search for elements.
LinkedList class: An in-depth explanation of the LinkedList class, including its constructor, methods, and use cases. Students will learn about how LinkedList works under the hood, how to add and remove elements, and how to search for elements.
HashSet class: An in-depth explanation of the HashSet class, including its constructor, methods, and use cases. Students will learn about how HashSet works under the hood, how to add and remove elements, and how to search for elements.
TreeSet class: An in-depth explanation of the TreeSet class, including its constructor, methods, and use cases. Students will learn about how TreeSet works under the hood, how to add and remove elements, and how to search for elements.
Performance of ArrayList, LinkedList, HashSet, and TreeSet: A discussion of the performance characteristics of ArrayList, LinkedList, HashSet, and TreeSet, including the time and space complexity of common operations, and when to use each class for optimal performance.
Best practices for using ArrayList, LinkedList, HashSet, and TreeSet: A list of best practices for using ArrayList, LinkedList, HashSet, and TreeSet in a program, including optimizing performance, avoiding common pitfalls, and choosing the appropriate class for the task at hand.
By the end of this lesson, students will have a strong understanding of the ArrayList, LinkedList, HashSet, and TreeSet classes in Java and how to use them to store and manage groups of objects. They will be able to choose the appropriate class for a given task, perform common operations, and apply best practices for using these classes in a program.
