Interesting, but means little without accreditation.
EDIT: Also, why’s it all Java?
EDIT2: Addressing the downvotes: If you really think that any employer these days is going to be happy with “Learned from a list on Github” on your resume then you’re sorely mistaken. It doesn’t matter if the courses match an accredited program. The accreditation is what matters because no accreditation = no diploma. Employers like diplomas.
Idk about American universities, but C++ was taught at Memorial University of Newfoundland when I attended 8 years ago. Granted it was a robotics class so maybe it’s different. Either way, makes more sense to me to learn C/C++ since most things are programmed in that.
