here is a quote from the java tutorial in the above url comparing java to C.
I originally saw a quote in a Lynda.com tutorial (which I no longer have access
to) that also stated Java to be a simplification of C.
According to Sun, Java language is simple because:
syntax is based on C++ (so easier for programmers to learn it after C++).
removed many confusing and/or rarely-used features e.g., explicit
pointers, operator overloading etc.
No need to remove unreferenced objects because there is Automatic Garbage
Collection in java.

Whoa now... Java is a lot of things, but it is definitely not a
simplification of C. You might call it a simplified ("different"
might be better) C++, but that's a whole 'nother thing.
C has very concise syntax.... you'd best invest the time in learning
it step-by-step, because little of it is intuitively obvious. But
it's not that hard, and it really won't take long if you know
assembler and/or some other language.
