NPEs in Java usually have 2 causes and they are easily preventable:
The problem is not really language specific because quite the same can also happen in any programming language, the symptoms/errors are just different.
Nulls are absolutely pervasive in Java and NPEs are not avoidable. At minimum, most of the ecosystem uses nulls, so most any library will have nulls as part of its interface. Null is an inhabitant of every type in Java (even
Optional, ironically). You cannot escape it. It's a fundamental flaw in the design of the language.Btw, you also can't escape it in Typescript, either, due to unsoundness of the type system and the fact that many types for libraries are bolted on to the original JS implementation and may possibly be inaccurate. But still, it's a lot less likely than Java.
