Do you have to pay to use the Java language (newbie)?

Question

Programming languages

Good day. I will say right away that I "googled". The question is, Do I have to pay for the programming languages ​​I use.
I heard that in C ++ you don’t have to pay for what you don’t use, so the question arose. At the moment, I have this idea: "You need to pay for a tool when you make a product with it or use it for business (Except for open source software). In particular, you are interested in JS PHP nodeJS python SQL etc. Tell me where I'm wrong, or write as it is.
PS If I ask a question in the wrong resource, then I apologize and direct me to the right one. Thank you.

Answer 1

Of those that I know, none of them are unnecessary, but many IDEs are already necessary.

Answer 2

In particular, I am interested in JS PHP nodeJS python SQL etc.

You don’t need to pay anything to anyone)) It
is possible that you have to pay, but not for using the language as such, but for using a certain development environment (the program in which you write your code), and even then ... (then the thought is not I will continue, otherwise there was already a similar precedent :))
PS And, well, or there may still be a compiler!
