The main introductory Computer Science course at Brown is CS015, an introduction to object orientated programming. It is a Java course aimed both at those with limited and those with no java and programming experience. CS017 is the equivalent course for those who have done a fair amount of programming before.
The lecturer for the course is Andy Van Dam who holds a highly esteemed position within both the Brown and the US Computer Science communities. More information about Andy is scattered across the net, but suffice to say he is a good lecturer.
