[JAVA] Let's do "Hello World" in 40 languages! !!

Speaking of programming languages, there are 2500 high-level languages in the world. Programming languages have their own characteristics, but the basic logic is almost the same.

TIOBE is a well-known indicator of the popularity of programming languages. We update the ranking every month. The figure below is the latest data for April 2020. Overall, Java and C haven't changed in popularity over the decades.
