Is this app enough for understanding? Anybody watches additional videos related to this?

Question

If yes, share please, some useful youtubers

Answer 1

Personal opinion: This app is the best for GETTING THE GRASP of java.
not mastering it. I saw on a blog of a java teacher and he said
"Every single person that is good on java passed through Java Tutorials™".
I'll post the link, when you think that you have enough understanding of
logic and everything you should take a look there.
I hope this helps.
