By that logic, every object-oriented language is just Smalltalk diluted with something. Dilution isn’t degradation. Sometimes it’s just called adoption.

JADEx is a solution designed to enhance null-safety in Java. Its key advantage is that existing Java developers can gain null-safety and final-by-default semantics without any learning curve. As a result, compared to migrating to Kotlin, JADEx offers a much more cost-effective way to significantly improve the stability of the legacy Java codebases that many companies continue to operate.

JADEx enhances Java with null-safety and readonly (final-by-default) semantics without requiring developers to switch languages. Existing Java developers can adopt these safety features with virtually no learning curve.

Compared to migrating to Kotlin, JADEx provides a significantly more cost-effective way to improve the reliability of large legacy Java codebases that many organizations still rely on.

In addition, JADEx provides immutability, allowing developers to strengthen immutability without the verbose use of the final keyword.

We hope you continue to show great interest in JADEx. Thank you :)

Let me correct a misunderstanding. JADEx was created as a Java superset language to strengthen Java’s insufficient null-related type system. In JADEx, Java’s reference types are assumed to be non-null by default, and through the nullability static analysis results provided by JADEx, developers can explicitly choose to mark types as nullable. Because of this, there is no problem using null-safe access operators and the Elvis operator.

To summarize:

• Java: All types are nullable; there is no non-null type. Therefore, Elvis operators and null-safe access operators cannot be used.
• JADEx: Both nullable and non-null types exist. Therefore, Elvis operators and null-safe access operators can be used.

I believe that if a company is a large corporation, it should provide financial support and take responsibility for large-scale bug reporting.

Unlike Java’s Optional, which is a library feature, JPlus provides null-safety at the language level. It allows developers to write code where null-safety is enforced consistently, without wrapping every value in an Optional. In that sense, JPlus brings the same kind of safety and clarity that Kotlin offers but keeps full compatibility with Java syntax and tooling.

What sort of financial situation are you in that 40$/month is sufficient?

I survive each day with just a bag of potato chips. Now, I’m reaching a point where even that is no longer possible. But rather than begging, I believe it’s right to offer my skills, bring value to others, and earn rewards in return. In the midst of a very difficult time, I came up with the idea for JPlus, and I’m deeply grateful for that. Without this project, I would have been in a much more troubled mental state. Through this project, I continue to dream of a hopeful future.

Thank you for your opinion.

I hope you’ll continue to follow and support the growth of JPlus!

The C Preprocessor also does all of those things. That’s expected of a preprocessor. If you say “you can write java code with a bit of extra sugar and JPlus turns it back into ‘regular’ java,” then that’s a preprocessor.

A simple preprocessor only performs code transformation and cannot analyze the meaning of the code or ensure type safety. However, JPlus goes beyond mere transformation by providing static analysis capabilities, such as generating a parse tree and checking nullability. It also includes functionality to automatically generate necessary Java code through the apply syntax. As a result, the combination of performing nullability static analysis and generating code via apply cannot be expressed or handled using any existing Java syntax alone.

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.

Thank you for the excellent question.

1. How does JPlus handle null safety in Java library interfaces?

• JPlus is currently implemented at the MVP level. Therefore, all Java library interfaces are treated as non-null by default. As a result, developers need to manually check for nullability when interacting with Java libraries.

• When referencing Java library objects, always declare the variables as nullable (type?) and use the null-safe operator (?.) when accessing them to prevent null pointer exceptions (NPEs).

• In future implementations, we plan to leverage nullability annotations in Java library code to add null-checking logic. However, since not all Java libraries include such annotations, developers will still need to manually handle null checks. The same applies to Kotlin: platform types are used, so developers are responsible for performing null checks.

2. If nullability information is a type metadata extension for compile-time checking, does that inevitably break on library interfaces when I create both library and consuming app with JPlus?

• In the current JPlus MVP, when converting to Java code, nullability information specified in the JPlus files is not converted into @Nullable/@Nonnull annotations.

• Therefore, using static analysis tools that rely on these annotations may cause issues at compile time.

• This feature will be supported in the next version, which will include conversion to @Nullable/@Nonnull. Thank you for your valuable feedback.

Finally, for faster responses, please post any future questions on the JPlus GitHub Discussions page: https://github.com/nieuwmijnleven/JPlus/discussions.

Didn’t I make myself clear? If you find it uncomfortable because you think it’s an advertisement, just move along. What do you think you’re doing? Look at the project I’m working on before you speak. You have no idea how much effort has gone into it. Calling it a scam is truly absurd.

First of all, thank you for your interest in the JPlus project. I also apologize if anything I said earlier came across as rude.

The point I think was misunderstood is that, while the content of the posts is similar, the links they contain are different. To clarify once again, the link in this post directs to the JPlus GitHub repository, whereas the link in the post you mentioned points to the JPlus blog on Hashnode. Please check again.

Yoy won’t find your target audience here on lemmy.

Instead you should look for companies that have open job/freelancer positions for maintaining legacy java code and pitch your project to them.

That’s a great idea. Thank you. However, I’m not sure if such opportunities would be available at my current stage.
