    Somehow you manage to make videos that fit just along side my curriculum of coding for beginners in my computer science degree. Really nicely explained, and helps me grasp the concept better! Thanks Mosh

    Hi Mosh, Thank you for all the tutorials especially C#, i just finished your whole course on MVC 5. Please make also a Course on WPF C#, you have the best teaching method and style here in YT, so clear and precise and whats great is it is for real world scenarios as i just got hired as a 'no experience' developer and these tutorials helped me a lot. Thanks again and God Bless you and your family. 🙏

    I started the video asking myself why i couldnt use the for each with the genericList. i start stackoverflowding not getting a good answer. little did i know the whole purpose of the video was explaning exactly that 🤣. Your way of teaching is very intuitive. i usually use your videos to understand and then complement with books once i do understand to get the intricacies of each topic.

I have learned a lot from all of your other videos for hobbies and now I know who to ask when I really need help! knowing that our country's public schools (and I believe most other schools) has a but of a struggle when it comes to teaching these kinds of things, would you be able to help us; at least with the basics?

    Why would I use "collection collection = new ArrayList()" when I could use the class that implement the collections like "ArrayList alist= new ArrayList(); " ? Would benefit does it provide to use the collection? I guess I missed it in the video. LOL

    - [00:33] 📚 Java Collections Framework Overview - Overview of the Java Collections Framework hierarchy: interfaces represented by green boxes and classes by blue boxes. - Hierarchy breakdown: `Iterable` interface, `Collection` interface, and sub-interfaces (`List`, `Queue`, `Set`) with added functionalities. - Explanations on common operations declared in the `Collection` interface and their significance. - [03:37] 🎶 Iterable Interface's Purpose and Problem Resolution - Understanding the `Iterable` interface: its place in Java, functionality for iteration over objects. - Demonstrating a problem with iterating over a generic list, highlighting issues with exposing internal implementations. - Analogies with remote controls and encapsulation in object-oriented programming. - [07:41] 🔍 Benefits of Implementing the Iterable Interface - Exploring the benefits of implementing the `Iterable` interface: independence from internal implementations. - Details on the `Iterator` interface and its role in simplifying iteration over collections. - Demonstrating the conversion of a for-each loop into iterator operations via Java compilation. - [09:02] 🧩 Implementing the Iterator Interface - Step-by-step implementation of the `Iterator` interface within the `GenericList` class. - Construction of a private nested class, `ListIterator`, and methods (`hasNext`, `next`) for iteration control. - Enabling iteration over a generic list without exposing its internal structure. - [13:06] 📦 Collection Interface Introduction - Introduction to the `Collection` interface: its representation as a container for objects. - Explanation of essential operations (`add`, `remove`, `contains`, etc.) declared in the `Collection` interface. - Insight into extending the `Iterable` interface and common implementations like `ArrayList`. - [20:00] 📂 Demonstrating Collection Interface Operations - Implementation examples using the `Collection` interface within the `CollectionsDemo` class. - Methods for adding, iterating, removing, checking existence, and converting collections to arrays. - Utilizing utility methods like `addAll`, `size`, `clear`, and others within the `Collection` interface. - [23:50] 📚 Converting Collection to String Array - Converting a collection to a string array allows access to string methods. - Utilizing `collection.toArray()` with a specified array type permits access to string methods easily. - Utilizing `var` simplifies code readability despite arguments against its usage due to clarity in object type identification. - [25:40] 🔍 Comparing Collections - Comparing two collections for equality using `collection.equals(other)` compares their memory references. - Checking for identical content between collections is done through `collection.equals(other)` method, which compares their actual content. - [28:02] 📋 Exploring List Interface - The List interface manages ordered collections where accessing objects by index is crucial. - List operations include adding, inserting, retrieving by index, and removing items at specific indices. - Features such as `list.subList()` provide functionality to obtain a sublist from a List. - [30:27] 🔍 Using List Interface Methods - Methods like `list.remove(index)` in List interface allow removal by specific index, a feature absent in general collections. - `list.indexOf()` and `list.lastIndexOf()` determine the first and last indices of an element, respectively, aiding in search operations. - The `list.subList(from, to)` method extracts a section of the list between two specified indices.
