what to do after ap java?

I'm a senior in high school and my ap java class is nearing its end. You can look up the scope of the class here http://www.collegeboard.com/student/testing/ap/sub_compscia.html
What java book/api/website should I study when this course ends?

I believe the problem there is that it is statically typed.

The weak type/prototype system in JavaScript is fucking stupid. I constantly find myself ensuring object meet contracts with hundreds of fucking:
if(something)
or
if(typeof(something) !== 'undefined')

Using logic statements in code to enforce variable contstraints from other scopes is fucking stupid.
