how hard is ap comp sci?

<p>i started to write programs since early 2011, using C, but I've heard JAVA is really hard, im going to take it next year, is it really hard?</p>

<p>My son is finishing AP com Sci and found it very easy. He also writes in C and did not found Java difficult( he prefers C+). If you already understand programming in any level, the concepts will be easier to grasp.</p>
