Hello, I have always had a passion for computers, since I was young, I am now 24 and currently work in marketing, I have decided I don't really want to follow this career path anymore and would like to pursue something I am quite passionate about.
I have no experience in programming languages what so ever, but would like to start and learn as much as I can, in turn helping me to work in software development.

I had a few questions I hope someone experienced can answer.

Which are the main languages I need to learn and which should I start first.

I was looking at Java to begin with then moving onto C++, I also wanted to know which were the most sought after certifications for the languages. What exactly do employers look for in these sort of job roles?

I don't want to run before I can walk just want a general idea and some advice really on the best course of action to get to where I want to be.
