Naive students cannot make a distinction between:
* the programming language
* the libraries, that can either standard libraries that
are mandated by the programming language standard, or
other application libraries
* the development environment

Now I am very sure that you know very well what the distinction is
between these items, so I am a bit surprised that you call facilities
for image processing "part of the language". Like C and C++, Java
does not contain any specific facilities for image processing in
either the language itself or in the standard libraries that are
specified in the programming language standard.

The additional libraries, like those for Java Graphics are part of the
Java platform, that contains a set of API's for many programming tasks
ranging from building GUI's to cryptography. The Java platform is
something very ambitious, there is nothing comparable for C or C++.

Learning to use a new library can be very difficult, but IMO the
API documentation of most Java libraries is very good compared with
those of many other complicated libaries.
