Think about what sort of programming you would like to do. Remember that writing software is only a way of solving some wider problem, so think what should that be? What would you love doing? To get anywhere as a programmer you have to undersand and enjoy working in the wider field. Very few people end up writing OS kernels or other "programming for the sake of computers". The rest of us make tools for other people (Word processors, painting programs, CAD, banking software, databases, you name it). Think which of these above would you enjoy working on.
Once you've decided on that, choose any language you like, and start working on some small relevant project. Once you have something put the link on your CV. At our company, once we get someone's CV and it looks good, we go to google and find what the guy has done. Publications, software projects etc. Then we decide whether to interview. During the interview we'll talk about that. We don't care whether the person can do Java or C++ if they're graduates. (even though we prefer C++).
