Make Your Java Code Null-Safe Without Rewriting (jplus.hashnode.dev)

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.

Isn't kotlin a better option?

Isn’t kotlin a better option?

Kotlin is great for null-safety, but JPlus allows you to enforce null-safety without rewriting your existing Java code, which can be easier for teams working in legacy projects or who prefer staying in pure Java.

AFAIK Kotlin and Java code can co-exist as source level. Never tried it though. I guess it depends on the end case scenario what to use.
