It can help with standardization and some security benefits to run things in the JVM, part of the reason it's so popular in enterprise

The argument I agree with is that Python is the best language to learn if it's your only language, and Java is the best first language if you're going to learn others. The syntax from Java is shared across so many other languages and it forces you to learn about things like objects and types. You could make an argument for C or C++ but Java's handholding is more beginner friendly imo

It's been interesting seeing the changes as they happened over time working with java pretty often for a good chunk of that time. The jvm and jit performance improvements, syntax changes and additional jep features added vs what was left out, tools for running and managing jvms, Sun & Oracle shooting themselves in the foot repeatedly, new jvm languages with scala, groovy, clojure, etc and their impact on java. I prefer other languages and tool chains for some cases, but java has been pretty good for building reliable, upgradable, extendable systems that get the job done & have a good large stable library.

Yet another Gang Of Four

There's also Groovy. A data execution pipeline program I use called NextFlow uses Groovy based scripts.

And compiling for different architectures can be very difficult. I've done a lot of work Power9 computers and it's not as simple as having the right compiler flags. Often the dependencies aren't built for your platform either so you have to go and compile those too. It can be quite a hassle.

fucking tomcat and jboss...🤮

The point of Java is to be a language for 90% of programmers. The vast majority of software development is not sexy, doesn't require a PhD. Java was intended to be a commoditising language and in that it succeeded wildly.

Python is interpreted where Java is compiled. They aren’t going to be able to be used in the same cases all the time.

The difference is people still write Java, regardless of whether it's a dated pos or not, so the use cases have evolved

Then there's the use of the JVM/JRE which have evolved even more due to Scala, Clojure & Kotlin

And Java is very much considered legacy in the vast majority of projects that use it.

Java is nothing like Rust. Java was always sold as a low skill programmer language, Rust has a steep learning curve. Java tooling has always sucked where Rust has excellent tooling pretty much since 1.0, Java is extremely verbose and needs a lot of tools to generate code to be productive at all, Rust is very expressive and most people write the code by hand or just use built-in language features. Java has a culture of "who care about that backtrace in my log as long as the app does what it is supposed to" while Rust has a culture that very much cares about correctness more than performance. Java was always driven by CEOs pushing it on people from the top while Rust is very much a language programmers try to push into their companies from the bottom.

Also, none of the languages you listed have a very particular niche that differs from what they were used early on apart from Java which is now mostly used on the server and used to also be used in GUI applications more.

it succeeded in holding back the entire field of programming for a decade via that mindset by having people blindly apply stupid Java design patterns to everything.

Python isn't really strict enough to be a good learning language and Java has too much accidental complexity that literally matters in no other language.

"Write once, run anywhere" is a pipe dream but Java came closer than anyone else by far.

You hate Java, you love Rust, noted.

Good day.

I learned C++ as my first language and it was a great way to understand the core issues of a programming language — like memory allocation, memory freeing, the difference between memory addresses and the memory contents themselves, threads, system calls, etc. Java obscures these nuances to a degree, but Python is too friendly and makes it hard to understand them at all.

I believe if you learn C++ you can easily learn any other language. After C++, I learned Python, JavaScript, and Java in a few days each without formal instruction. If you learn Python first, you’re probably going to struggle learning those other languages because you haven’t grasped the lower level concepts yet and may never if you’re not in a formal setting that forced you to learn them.

No one disagrees that Python is easier, but if your goal is to get a foundation in programming that allows you to easily pick up other languages, you should start with C++.

COBOL is still being updated because, believe it or not, people are still writing COBOL

I attribute Java's uptake to a large amount of marketing and support, which led to a massive ecosystem. Even a mediocre language like this one can find success when propped up like that.

Yes, I have Java and love Rust but the point is that if you say they all go through the same cycle there need to be some commonalities between the languages and the way they rise to popularity and there just aren't. If any modern language resembles Java's rise to popularity it would be Go.

First learn C, then learn C++, then learn Java. In that order, each will make you appreciate what the previous one lacks. From there, you should pretty much be able to learn anything.
