Null is biggest flaw of Java, saying some developers. Null causes NPEs causes crashing software. IMHO this is the same vibe as C vs Rust and I totally disagree. Crashing software is caused by developers and not by the programming language.
The easiest and best way to prevent NPEs is … proper exception handling. It is as simple as it sounds.
Bye the way, NPEs are often a side effect of OOP. All Objects are unsafe until you checked them. But checks are unsafe so go with exception handling.
