Java Iterable vs Iterator tutorial and code

In this video I implement a wrapper over a list which implements the iterable interface and creates a new iterator class. I then show how to use the for loop shorthand to loop over our own custom collection class.

Surfed all YouTube and then I came across this video. Thank you, it is a very good explanation.

Classes just went online and my cs professor decided now is a good time to give less direct answers than when we would meet face to face a few times a week. Her help to me not being able to understand why I couldn’t iterate through a generic arraylist using a for each loop but a regular for loop works fine was that it should work and if not I should be able to find a solution online. This was amazing ty

Somebody has well said "hands-on trial is way better than reading".
Great explanation 🔥🔥

Shouldn't the logic in hasNext be: " if ( internalList.size() > indexPosition + 1 ) " ?? And not " >= " ? If the size is also equal to the position + 1, that means we are at the end of the list, and there is no next element. Example : we have a list of two things, ["bob", "jane"]. The size would be 2. If we are at index 1 in Java, we are at the 2nd element ("jane"). If the "size" (2) is equal to "index + 1" (2) your code says that it hasNext or has another element, which isn't the case.

Hi, Aaron, you are the best teacher of all Ukrainian programming teachers on the YouTube, I am from Ukraine, thank you for this lesson, it was very interesting for me.

[daloshy]

thank you this was extremly clear, best video I found about this topic (:

[williamchisholm]

Great tutorial, very straight forward.

[conradlarrson]

Sweet, cleared things up for me. Thanks.

I have watched this video several times and every time I learnt something new and existing, informative that I REALLY wanted to know. That's why I wanted to say thank again. Thank you so much teacher. You are THE BEST!

0:22 Iterable(I) uses "iterator" method to provide Iterator(I).
1:20 implement manually
10:19 enhanced for loop

Thank you for the help! You made this concept click!

[apoozeo]

Thanks for the video. (I am sure I heard a train in the background! :))

ok and i guess you don't need a class to implement iterator if you only need the default next and hasNext behavior because the List class has it's own iterator() method that returns a Iterator. So in public Iterator<T> iterator() method you can just return MyList.iterator();

this was a very disent tutorial. Do you have a tutorial on customizing the desktop enviorment?

[blabla]

thank you so much, this video saved my ass!
i love you dude!

How would I iterate starting from last index to first index?

lol my man is takin the key board out back and boxing the shit out of it other than this gr8 tut

[philipT]

u say in the intro that u gonna keep talking about the collecation interface, where can i find that vid?

[deli]

Hmm, I think it would be helpful if there was a simple description of what they are first. By your definition, there's an interface that has a method which is also an interface. ...see what I mean?
