Can I learn java here with full concepts thoroughly

Answer 1

Similar to what Ace said, you can only learn the basic concepts of programming at SoloLearn.

SoloLearn doesn't offer a full course to any programming language, nor does any website/app on the Internet. There is no possible way to completely master a programming language just by indolently sitting on your couch and reading what's written on your monitor.

The only possible way, to completely master a programming language is by the infamous "trial and error" method. What you basically do is, keep trying out different techniques to do different things. E.g In C++, the basic exercise to understand the logic of the For Loop is to create advance shapes like a diamond using zeros and whatnot. So although there are several Static and Dynamic methods to do this, there is only 1 method which is the best, and to discover that method, you have to :

Eat
Sleep
Test
Repeat

Just by following this easy method, you can master any programming language out there!
