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.

There is one Groovy syntax that replaces some Java syntax: code blocks now become closures.

What you can write in Java as

{
    System.out.println("Hello, world!");
}

You would have to write in Groovy with a label

l: {
    System.out.println("Hello, world!");
}

Groovy doesn’t have null safety or boilerplate code generation features. That’s why JPlus was created to address what Java developers truly feel is missing. Go post that comment in the Groovy community.
