can you define web projects? its funny you ask this because i have been researching web development in java for the past 4 hours and i get on here and see your post. I think that specific blog is pretty obvious and easy to understand considering. C is always gonna be 1... not going away anytime soon. java because android uses java... and objective c cause ios uses objective c.
but I would really like to know what you mean about java for web projects? specifically.
