A question about this video
Hi, I find the unenhanced for loop to be better when we want to output a elements index number and the element itself like?:
System.out.printf("%d : %s", i+1, something[i]
how do we even do it in the enhanced for loop?
in some cases the enhanced for loop is better and is some cases the other am i right?

You're right that you should use the loop that's more appropriate to your task and that you can't print the index with the enhanced for loop (that I'm aware of).
Generally if you don't need to work with the index directly the enhanced for loop is a better choice for iterating over a collection, but as you've pointed out that's not the only use of loops.
Edit: Thinking about this a bit more if you're working with an object that has an
[object].IndexOf([stored-item]) method you could use that, but it's probably more expensive than just using a plain for (;;) loop.
