JPlus is fully compatible with Java, offering modern language features like null safety, boilerplate code generation and other modern language features to reduce developer burden and maximize productivity.

Notably, there is currently no ‘superset’ language that keeps Java syntax almost intact while extending the language with features like null checks at the language level. JPlus aims to fill this gap, providing a language that existing Java developers can naturally learn and adopt.

But there is a reason for null, its a really nice thing you can work with.... I really don't understand all the fuss about null safety, working against the language

I want to write functions that fail at compile time if called with a null object. You can use annotations to kinda do this, but they do not produce compile errors.

This is exactly the core problem that JPlus aims to solve.
