As I understand, Java has two classes of data types: primitives and objects.
The first is a very tiny set that includes char, boolean, int, double,
short, and just a few others. The second is a gigantic set, which includes
all the thousands of classes in all the Java standard libraries. Is this
second category available from Ada (or from any other language, for that
matter)?

Also, I'd very much like to have a URL to a source where I can read more.
