Is code injection possible in Java?

Question

nowadays you can read much about code injection, exploits, buffer-, stack- and heap-overflows etc. leading to inject and run code. I wonder what of this stuff is relevant for Ja

Answer 1

If it was possible, Java would already have been dead for long.

On the other hand, SQL injections are very easy to avoid by using PreparedStatement to store user-controlled input and XSS is also very easy to avoid by using for (re)displaying user-controlled input at the webpage.
