Best programming language for Science Project?

Many navigation applications are done in Java not only because it's portable but also because it contains the basic abilities to draw things (whereas C++ would require you to load an OpenGL library for things more complex than simple lines and filled shapes). To be honest, I'd pick C++ if you must integrate all 3. C++ would be best if you were trying to do a dynamic program that could grow as it contains the ability to use pointers (which you can't really do in Java) and it is well doented in the area of linked lists (which would help in terms of artificial intelligence and cryptography).
