Depends on what you mean by "integral". Java 1.5, purely as a language
(i.e. without the libraries typically bundled with the compile), has no
concept of GUIs, but it does have special support for iterating through
every element in a collection, like so:

for (ElementType element : collection) {
doSomethingWith(element);
}

The classes "List", "Map", "Set", etc. are part of Sun's class library
which they give out for free along with their Java Compiler. As far as I
know, there's only one other (serious) class library one could work with if
one chose to forego Sun's, and it is called "Gnu Classpath", whose main
purpose seems to be to replicate the functionality of Sun's library, but
with open source "free" (as in freedom) code instead of proprietary code.

As for GUIs, Sun also provides two APIs, one called AWT (which is
deprecated now), and another called Swing. IBM also provides a fairly
popular API called SWT.

I think Java and its standard class library provide rather poor support
for webbing actually. I think all you get is an XML parser, and that's about
it. You either have to download the rest from 3rd parties, or write your
own.

There's something called JSP (Java Server Pages), but I don't know much
about it; for example, I don't know if it's from Sun, or some other vendor,
or if it's an open standard of some sort.
