Now, we can ask whether the design of Java in general makes it harder
to make programming errors. It may do that, I don't know. But it's
not because the language spec says there's no UB. AFAICT, the only
thing that the presence of UB can possibly affect is debuggability,
and as I've posted elsewhere, I doubt the effect is entirely negative.
From my limited experience, Java makes it harder to make mistakes but
compensates by making it harder to diagnose and correct the mistakes it
allows you to make :)
For certain types of mistakes. For others, it's just the
reverse. My experience is that it is easier to write correct
applications, at least complex applications, in C++---it
requires less programmer effort to achieve a high level of
robustness. But that's a global experience. It says nothing
about any particular individual feature. Some of Java's
features have a positive effect on programmer productivity
(where productivity is measured in the amount of effort
necessary to write correct, robust and maintainable code):
garbage collection is one, of course, but so are things like
guaranteed initialization, bounds checking of arrays, and
guaranteed order of evaluation.
