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.


I don’t think anyone’s calling it a scam, but it’s pretty clear as an outside observer that a very specific point was questioned (about where JPlus fits into the existing ecosystem) and your replies have very little to do with that topic.
Also, your replies really do look AI-written. I know it’s hard to be sure, but humans expressing a point don’t usually write summaries in the fashion of your replies and LLMs almost always do.
Anyway, personally, if I have an existing application java program then maybe there’d be an argument to use a lightweight syntax extension to continue developing it more safely. But if I were starting a new project, whether a library or application, I would just use Scala or Kotlin from the get-go. The JVM platform is already versatile enough to get us much more than just some basic extra type safety and boilerplate generation. I’m all for static analysis tools, it’s just (again) hard to see what you get from JPlus that you can’t get from either groovy or a better language.
Your replies don’t address that at all.
JPlus follows standard Java syntax while aiming to be an “Upgraded Java” by adding features that Java developers consider practically useful in real-world projects. This allows existing Java developers to utilize new features with minimal learning curve. All features are added on top of Java syntax. For example, null-safety syntax (type?, ?.) and boilerplate code generation syntax (apply). As a result, developers can experience an enhanced version of Java while continuing to use existing Java code and libraries without modification. This should clarify exactly where JPlus fits in the ecosystem.
