CodeGym is one of my favorite Core Java online courses. It’s very practice-oriented. There are more than 1,200 coding tasks with code validations and tips to help a student solve tasks. Also, it contains short lectures that cover all core Java topics (except lambdas, for the moment). - Source: dev.to / over 1 year ago

I started learning it from their russian version (this course was originally written in Russian) but if English version is as good as Russian, then it's probably the best way to start learning java, as they have probably few thousands of exercises https://codegym.cc/. Source: over 1 year ago

If you want to take a slightly longer, but imo easier path. I went from learning coding using https://codegym.cc/ to being a Software Quality Assurance Automation Engineer (current) and will eventually transition to BE Dev on my company's dime: At the last 3 companies I've been a QA Engineer at, there's always been a pipeline from QA -> Dev that the company is willing to work with you on.

You could try something interactive CodeCademy to get them started, or something game-based like Code Combat or Code Gym. Alternatively, try finding any local groups or classes aimed at teens. Source: about 2 years ago

Great job! I also set a Telegram channel forwarding the dailycodingproblem.com. I'm sharing the link here if someone else needs: https://t.me/daily_coding_problems. Source: over 2 years ago
