What are the best coding languages to learn to make yourself more employable?

Question

More specifically, I am a college student studying Physics, and would like to work in Automation / Process Engineering. I have experience with Arduino, C++ and other programming languages used for PLCs, but I would like to know what other languages would be useful.

(Also, I am aware of the Stack Overflow Poll that lists coding languages by popularity, I am just asking for some of your personal opinions.)

Answer 1

I think its java, most of everything is made of java these days
