i have known and been using Java for a year. I have been doing few web application projects using JSP and Servlet, with assistance of course. And then i realized that I only have so little understanding about Java core, logic, structure etc. I really want to understand Java structure from the beginning to be able to implement the logic using the language.

I have few online tutorial such as w3school as a platform from me to learn. But, there are so many opinions about the website tutorial whether it is worth the time or not.

Does anyone have the recommended online tutorial for learning core java? Especially free tutorial would really suffice.

The obvious starting point is Oracle's Java Tutorial. https://www.tutorialspoint.com/java/ and https://www.javatpoint.com/java-tutorial are also worth checking out.

The Java™ Tutorials are the most comprehensive resource I have seen, but they use the old technique of putting code in the main method. That was the most convenient way to run a block of code as such before JShell, but it doesn't teach OO programming. I have never seen a really good tutorial on line.

So what is your personal review on w3school for Java or any language you ever did?

Hi,
 I am lecturer in Java and a few months ago started a YouTube channel (https://www.youtube.com/channel/UC47bUeEug64OqfM42EBVPRA) called "Let's Get Certified" to help people prepare for Java Certification. I take Enthuware (excellent tool) questions and explain them with diagrams and code. I have over 150 videos up there and am posting daily.
  I have a PlayList "Java Fundamentals" that may be of help (no Enthuware questions here as they are a bit advanced for that in my opinion). Topics like scope, Java identifiers and call-by-value are there. As Certification is the primary goal, there are not many videos in that playlist at the moment. However, if my videos help you then please suggest other topics that you would like covered and I will do videos to cover them.

Regards,
Seán.
