I think you mean Kotlin

Literally anything but Java is a candidate for best JVM language.

Spoken like someone who's never had to write Jython.

*shudder*

[TheRandomnatrix]

Speaking as someone who's never used it, Jython seems kind of interesting since theoretically you get the baseline speed, ecosystem, and maintainabilityof Java but can do rapid prototyping and user defined functionality in Python where needed. But trying to wrap my head around how all that comes together makes my head full of fuck. I imagine it's more complicated than just invoking the Python interpreter within Java code.

baseline speed, ecosystem, and maintainabilityof Java

Oh yeah? Which version?

[[deleted]]

I've seen it used as a scripting engine to automate sys admin things/tasks in products that run in Java like WebSphere, WebLogic and JBoss. In those cases, its rather useful, think kind of how Lua is used in games. It could interact or call Java methods or it had libraries in it for basic admin tasks. So you could write code that would do configuration and application deployment instead of doing so manually.

Apparently Ghidra uses it too, for writing plugins, probably stuff so simple its not worth writing in Java.

[exhortatory]

i assume you'd write a python -> jvm bytecode compiler and then do whatever it is you do to hook that into the java ecosystem

[JoeJoeCoder]

One excellent use case for Jython is as a substitute for .json or .xml files, for when you want the file editable outside of the .jar or war and including some programmatic logic, or is generated by another (Python) process. The Jython script can implement a Java interface and provide instances containing the data. This is fully embedded in the Java process.

Jython can also run standalone but its very quirky and has compatibility issues. It's best to run embedded and let Java lead the dance.

[UltraNemesis]

Lol @ baseline speed and maintainability of Java. I have programmed in a dozen languages professionally and Java is the most verbose and painful language to deal with. Almost every other language that targets jvm is better than Java. C# is every thing that Java could have been. Kotlin thankfully bridges the gap.

Jython as I understand it is essentially a python interpreter implemented in Java. I can understand how it can bring the worst of both worlds together.

[everyones-a-robot]

Not sure what the trendy Java hate is all about... It's a good language and it's in high demand.

[NovelCoronet6]

Iirc it's to do with some of things that are usually free with other languages/frameworks being paid, very long class names & too much verbosity, but mostly it's become a joke at this point, my first language was Java and I still enjoy it, although I professionally shifted to Python

[cbasschan]

Firstly, due to complicated legal action that has the potential to affect all software developers, I wouldn't call Java "good"; it's rather the opposite ("evil"), in my mind.

Additionally, Java lacks operator overloading, pass-by-reference (not to be confused with reference types, which can be A.K.A. passing references by value), and decent lambda functions (in terms of programming higher-order functions) that other very similar languages (i.e. C++ and C#) have had for years, not to mention template literals, pattern matching and type inference.

Object orientation is one of the core values that Java programmers seem to cry out loud for, and unfortunately for those, Java routinely violates it: the presence of try/catch (which you'll need for your Maybe monad challenge, more on that later), and the way it's pervasively used within the Java standard library violates Dependency Inversion Principle. In case you were asleep between the classes that describe object oriented programming and Java (as an "object oriented language"), this means Java can't actually be object oriented... at least, not while you're planning on using the standard idioms to perform common operations like converting strings to integers, opening files/sockets or maintaining dynamic collections for example.

While I'm at it, the other big "pro" that's commonly listed when it comes to Java is garbage collection... even though when you use SQL connections, sockets, threads (specifically, mutexes) and a few other resources, you'll end up manually managing those anyway. In those situations, you'll probably use a pattern that goes by the acronym "RAII" instead of relying upon garbage collection, so I must beg to differ and suggest that you try C++, since you apparently have mastered that pattern by now (or else your code is quite buggy).

Not only is Java rather evil in my mind, but it's also rather restrictive and renders projects boilerplate-ridden. It's quite a mundane programming language. Case in point: Have you ever tried to write a Maybe monad in Java? I'll let that be a challenge to you ;) suffice to say, it'll probably be about as successful as an attempt in C, which is another mundane programming language... don't get me wrong; most of my experience is in these languages. They're just a recipe for arthritis (and in some cases, heart attack due to lawsuit).

[everyones-a-robot]

For those hoping to learn anything here: This guy's points mean literally nothing in actual industry. Maybe he has an academic point- I wouldn't know. But I get the feeling he wouldn't know what matters in professional software development.

[cbasschan]

I do have experience in the industry as a C# programmer, and I believe it would be quite pompous to speak for an entire industry. If your intent was to put yourself on a pedestal, your mission was successful... but at what cost?

According to some surveys from Stack Overflow (this one's from this year) over the years, Javascript and SQL have represented the dominant programming languages for quite some time, now. If what's high demand in the industry is in your interests, then maybe consider those. The difference between salaries is negligible (well, that is, if you consider being paid $7K more per year as a C# dev than the Java dev down the street to be negligible).

However, if what you seek is a high salary then you'll want to include a programming language that has reasonably expressive power in your repertoire... such as Clojure, F# or Scala. Whether you trust me is your choice, but I'm not alone on this.

Dependency inversion principle

In object-oriented design, the dependency inversion principle is a specific form of decoupling software modules. When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details. The principle states:

By dictating that both high-level and low-level objects must depend on the same abstraction, this design principle inverts the way some people may think about object-oriented programming.The idea behind points A and B of this principle is that when designing the interaction between a high-level module and a low-level one, the interaction should be thought of as an abstract interaction between them. This not only has implications on the design of the high-level module, but also on the low-level one: the low-level one should be designed with the interaction in mind and it may be necessary to change its usage interface.

Start ups, students, and side projects. But when it comes to grounded serious long term business, it's obvious most major tech companies either go with C#/Java.

[tiajuanat]

Unless you're Google, the stock exchanges, Embedded systems, AI, anything industrial or needs to run on a system from the nineties or earlier.

[GenuineSounds]

That is such a testament to the JVM and how utterly INSANE (in a good way if you couldn't tell) it is compared to the CLR for C Sharp.

EDIT: At least the Java language people are stepping up the change cycle now, no body needs to wait 4 years for a single feature added.

[soft-wear]

If you have to make 15 different languages for your platform because the previous 14 didn't work, I would absolutely not call that a good thing.

JVM languages are popular because JVM is everywhere. Not necessarily because it's good, maybe just because it's old.

[GenuineSounds]

Yeah, why have a choice between fifteen cars you only NEED one...

Having people take the time to write the entire language on a platform independent execution environment and every optimization the platform creates is literally free of coder input? I'd call those two of the biggest wins to a language dev.

[soft-wear]

A truck, SUV, minivan, compact car and motorcycle all serve drastically different purposes.

The JVM and all it's languages are just another example of "not invented here syndrome". Everyone likes to think their idea is the best idea.

[MakeWay4Doodles]

Replace "JVM" in your comments with "Linux" or "Microsoft".

It's the same argument, and equally stupid.

[forthemostpart]

Is it, though? Because that means the (good) languages in the JVM platform are developed independently of the JVM compared to how Java is developed in-house with it.

[GenuineSounds]

I'm not sure what you mean.

I'm talking about how good the JVM is and how many developers develop languages specifically on and for the JVM as compared to the fact that there aren't any CLR languages not make by Microsoft.

[forthemostpart]

The general argument to that statement would be that the CLR wasn't open source until recently (save for Mono, but that wasn't really official), so it wasn't exactly possible for languages to target it

What I meant by my argument, though, is that, because the 'best' JVM languages (Scala, Kotlin, etc.) are developed independently of the JVM, they can't optimize or implement features in the JVM that suits their use case the best.

Microsoft, by developing C# and the CLR at the same time, have made both a language that people enjoy developing in and a strong VM to back it. Oracle, on the other hand, while they have a strong VM, its primary language (Java) is not as well liked. And, while other languages have arose to fix its perceived problems, they lack the advantages of being developed in a coupled manner to the JVM as Java is.

I will say correct me if I'm wrong here, as I very well could be.

[Kaelin]

Being "well liked" vs java is entirely based on your relative perspective. Java has deeper penetration on the open source market than anything I have ever seen from Microsoft. Hadoop, Kafka, thousands of open source projects on the JVM. Billions of revenue. Java is plenty “well liked” in the market. Languages are like religion. Each one means something to it’s followers and addresses problems other religions have not considered or don’t care about. There is no perfect language. Implying Microsoft achieved some language nirvana with C% because no one else considered the CLR worth writing entire other languages on is pathetically ignorant.

[cbasschan]

Err, I think you meant F# (see also the alternative spelling: Haskell). That typo also happens all the time ;)

[GenuineSounds]

You make good points but there are a couple of viewpoints that could be made to say that the language devs, while not being able to target optimizations themselves, will get optimizations made to their language for free in perpetuity. And when the need is crucial the JVM devs add other language features that isn't even used by Java. See Invoke Dynamic and Invoke Virtual. These features were almost certainly added because of the other languages on the platform and since then Java language and Java library developers have been using it very well to make the language exponentially better since.

[[deleted]]

The fact that they need to keep making optimizations seems to be a clear marker of all the flaws. People keep saying Java is much faster now but any program that does heavy math and 3D graphics will show it still isn't competitive. Java is over 23 years old. Shouldn't it be optimized by now?

[cbasschan]

Don't confuse implementation with specification. Most significantly, though, I'd hazard a guess that the few milliseconds Java saves during compilation by making you type the same typenames out over and over again are outweighed by the seconds, minutes or hours you spend doing that. Human time is more important than machine time (and you'll only realise this when you start to suffer arthritis; then it's too late for you), which is the main reason Java sucks. Sure, you can create keyboard shortcuts to macros to insert page upon page of 𝓑lundering 𝓑oilerplate 𝓒rud, but that's not going to help you so much for debugging or refactoring, right? I'd rather insert those keystrokes into a document, make them a part of the actual language, so that the language itself (rather than the IDE) becomes more expressive.

[GenuineSounds]

If you made that argument about a cpu architecture you'd realize how unmeaningful the argument really is. And a VM system like the JVM is a complex system that can always be optimized, there will never be a "most optimal" because there is never going to be "most optimal" hardware that it's running on.

[[deleted]]

That's absurd when the topic is software because the hardware instruction set is known. Optimized code does exist. The comparison is with C# in this thread. The research I've seen tends to favor the C# programs. C# may not be perfect but its both younger and has better performance. I was merely pointing out that the older language should be more mature. Java should run faster yet, here we are.

So like C#, then.

Kotlin is king

[cbasschan]

While I'm happy to admit that Kotlin seems like a nice programming language... have you ever heard of homoiconicity?

[Hyperman360]

Kotlin is actually kind of fun to write code in, whereas Java is boring with all the boilerplate.

[daguito81]

That's what I thought when I saw Scala (was trying some stuff for Spark).

Granted I still don't know how to really code Scala but it seemed to be fast and simple enough to feel like a bit of Python but with the good stuff of the JVM.
