Java at 30: How a language designed for a failed gadget became a global powerhouse
Java at 30: How a language designed for a failed gadget became a global powerhouse
Lol, as Javanese, It's funny that Javanese ethnic name -> Javanese coffee -> Javanese programming language.
People still keep thinking that I was a programmer or making a typo of Japanese everytime I mention I speak Javanese.
The language was initially called Oak after an oak tree that stood outside
Things could have been a lot different!
Oakscript does have a certain ring to it
"fucking oak what the fuck" still works so not that different
I think Java was first released just after I graduated. I do program Java at my day job though, and I don’t mind it. It has its quirks but I find I can express myself using Java, but I probably try to think towards much in OO paradigms when I design and code.
For your information, since java 10, 2018, 7 years ago, it's
var thing = Thing like most languages.
You should update your java knowledge.
You can do var thing = new Thing(); now.
This dude came to my spouses work to do some sort of work/help (I don’t know the exact details) and someone wrote a doc he needed to review. It was a lot of work not just like a few notes but a proper doc and all he wrote back upon “reviewing” it was a thumbs up emoji!! 👍🏻 everyone was shocked lol, no feed back, no notes nothing just 👍🏻
👍
java was my 5th language, having just missed it as the AP CS language in highschool by a year. oddly i could not get behind such a massive standard library having come from BASIC, Pascal C++, ASM, VHDL. now after 30 years of programing i write Java web services for a living. feels strange.
Oddly, I did know some BASIC and I have vague memories of the numeric line starters like 10 with white text on a black background giving it a retro feel.
Fuck Oracle.
One Rich Asshole Called Lary Ellison
His political contributions are really on brand. He funded election deniers in 2022.
Also I've heard Oracle has a bad reputation when it comes to government contracts, very expensive poor quality software ripping off our taxpayers. I think they ought to be blacklisted or at-least require extra review due to their reputation. CUNY paid Oracle over $600 million and look at what that got them: https://pscbc.blogspot.com/2013/03/cuny-first-computer-system-to-aid.html. To be fair the article does claim that "The project required an expenditure of up to a billion dollars to do it right. CUNY Central offered far less. All but one of the bidders dropped out as a result". I'm confused why it needs to be so expensive, even $600 million seems like way too much.
Lary Ellison is one of the richest men in the world right and owns some kind of private island or something that he bought basically after showing his shares of Oracle stock?
30 years of pain
Java was also my first introduction to programming as it was included in Computer Science in final year of school (at college, we did the trusty C).
I think they have replaced Java with Python now in schools because of the latter's popularity and also because many would argue, Python is slightly easier to learn than Java.
In a first year computer science course at uni I can say they teach us Python, Java, and C, all with slightly different use cases.
Python is easy, but it can also be infuriating. Every time I use it, I'm reminded how much I loathe the use of whitespace to define blocks, and I really miss the straightforward type annotations of strong, non-dynamically typed languages.
Try 'Nim'. It is Pythonic language with static typing.
I hated something about Python, and avoided it, until encountering Tcl which for me fulfills the same role that Pythons seems for many people, but Tcl is really much more pleasant. IMHO.
Most overrated language imho. I actually enjoy Java more.
You can annotate types in Python, and it's actually pretty nice when used with Pyright/Pylance.
use bython, python with braces XD
Preach it! 🙌⛪
I don’t think weakly- or dynamically-typed languages are a good thing to base computer science curriculum around. Yes, it’s “easier”. But you will genuinely have a FAR better understanding the language and the logic you’re writing in it if you work in the scope of strong and static typing - or, at least have linters that force you to (e.g. mypy for Python)
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
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.
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.
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++.
Imo people should start with C first since it is a lot simpler than C++ while still providing a lot of what you mentioned. C++ adds a lot of things like name mangling, templates, L & R value references that can quickly make things a bit more daunting for beginners.
I also generally find error messages for C a lot more parsable for beginners than C++ ones.
C++ is a monster. I'd suggest C instead to learn about these basic ideas.
They did, but it makes me sad. Python is becoming the next JavaScript because of its ease of use.
The Java guys simply don't understand how to code without the gang of 4 crutch to lean on.
Python is interpreted where Java is compiled. They aren’t going to be able to be used in the same cases all the time.
Not true. They use the same model, executing compiled bytecode. It just feels like directly running a script because Python compiles it to bytecode on the fly, and because it is embarrassingly slow.
I remember Java being seen as the best thing ever in the 90's, and it was considered "cool" at that time. So cool even, that it became the programming equivalent of a hammer, every coding challenge looked like a nail for which you could use it.
It's a cycle all popular languages go through. First only experimental applications and super opinionated programmers use it. Then everyone wants to use it for everything. Then it finds a niche where it excels and settles.
I remember Java, C++, Python, and JavaScript going through those phases as well. Currently, everything is Rust.
What is the "everything" that Rust is being used in? From what I've heard its being used in the same place you'd use C or C++, not in any other niches.
I'm still wondering what Java's niche is, it seems like it does everything, but nothing particularly well. I guess it found a home on Android, but I don't think that's because it's particularly well-suited for it.
JavaScript kind of had a weird path though, with like a rebirth on server side, and then all these trendy libraries and frameworks and other bullshit.
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.
Java is IMHO one of the most underrated platforms outside of enterprise environments.
Most people also forget, that Java is not only a language, but also a platform, an ecosystem and active research is applied to many parts of Java.
Concerning Oracle: OpenJDK is actively supported by very different but big and capable companies (IBM, Amazon, Eclipse Foundation...). The quality of the language, libraries and documentation needs people which are payed to work on this, full time.
Bring to this the free IDEs one can get for Java - Eclipse and Netbeans are a little bit old school, but offer everything to build/debug and develop complex software.
Java is not my favorite programming language, but when I want to write interesting software and ensure it will be running for the next decade w/o significant changes, Java is really hard to beat.
Of course, in hindsight we know how to do a lot of things better as they were done in Java. Still, what other open source Language/Platform/documentation with the backing of capable companies and really independent and interoperable builds are out there?
One last note to all people which were damaged by Java in university or school: Usually the teachers/professors/lecturers have no real world experience of software development besides the usually university projects, and for the usual university projects which basically means getting small to midsize projects to run Java is total overkill.
Don't confuse this with real world software projects in the industry, which are mission critical and need to work a decade from now on. Java was always a bread and butter language, but one which learned from other languages and even the verbosity makes sense, once one dives into code written a few years back by another person.
Usually the teachers/professors/lecturers have no real world experience of software development besides the usually university projects
Adding to this: university projects are built on a relatively short timeframe compared to many industry projects. The growing pains that typically occur after a few years of continuous development is unlikely with the small scale of university projects.
I wouldn’t go to a university professor for advice on how to build a system that will last a decade of development.
My 2 cents is that it would have flourished a lot longer if eclipse wasn't stretched so thin like using a very thick amorphous log that is somehow still brittle? And ugly? As a bookmark.
I keep Java installed for one thing and one thing only... modded Minecraft.
Unlike other older languages, such as Cobol and Fortran -- which are still used, but almost always in legacy projects -- Java has constantly evolved to meet new demands while maintaining backward compatibility.
can't speak on the FORTRAN claim but with COBOL this couldn't be less true. last i checked the newest Enterprise COBOL LTS is newer than Java's
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
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.
JVM isn't mediocre. Really-really.
I don't like something aesthetically about Java, can't quite nail what, and don't like long-long namespace strings, but these are my personal limitations.
Ah. I also don't like OOP.
I am going to be decapitated for this, but you're totally right.
You only have to look at Rust. An horrible language with a massive hype machine and an army of zealots pushing it everywhere.
I can't understand how people are complaining about the java boiler plate and its verbosity, while promoting Rust every time they can.
For me it's the tooling surrounding it that makes it nice.
Yes, that's part of the ecosystem. :)
OOP was hype during the 90s. Schools adapted their curriculum to this trend. So they needed a programming language for this, and Java became the choice. C++ is too tricky as a first language.
The result is that a lot of people knew Java, which means it’s a good choice of language if you want to recruit programmers.
I believe most of Java’s success was luck. It released at the perfect time.
Java was the new hotness when I was in the middle of my comp sci degree. The biggest benefit I found was javadocs. Other languages had shit documentation that usually didn’t match reality in comparison.
Yes. JavaDoc was/is good.
There, I said something nice about Java. I'm giving myself a gold star, and going to stop typing.
I liked Java a lot more before Oracle acquired Sun. I've used Oracle databases enough to hate Oracle with the passion of a supernova.
I think I need to clear a common misconception people seem to have here: Oracle has very little to do with Java.
At most, Oracle has the following connection to Java:
However, Java as a language's baseline comes from OpenJDK, an open source (GPL 2.0) community project which is upstream to several builds including Oracle's JVM. It follows a "bazaar" like development model similar to the Linux kernel where you can see their mailing lists and track what's being worked on. Anyone can contribute and the code is on Github: https://github.com/openjdk/jdk.
That being said, you don't even need to use Oracle's JDK (it sucks IMO) and use one of the community provided builds of OpenJDK. OpenJDK builds are provided by Eclipse, Amazon, Azul, Bellsoft and even Microsoft provides JDK/JRE builds. These are free of cost and have longer term support than Oracle's offering.
Open jdk is where it's at
Yep, thanks to the AdoptOpenJDK project which really helped make OpenJDK builds available for all platforms. (It is now called Eclipse Temurin and Adoptium.)
A language I wish would die already, but there are still vendors that program in it, along with freaking Tomcat hosted applications. EduTech is still stuffed to the gills with it.
fucking tomcat and jboss...🤮
There's always Kotlin. Of course I never understood the desirability of a VM language in the first place, why not just compile for different architecture?
JIT compiling and byte code morphing and instrumentation. For instance data base persistence is usually done by instrumentation tools, that add instructions to keep track about transactions and modified objects, or new objects that need persisting. And endless more things.
"Write once, run anywhere" is a pipe dream but Java came closer than anyone else by far.
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
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.
I used Java years ago for Android dev, but stopped when I stopped doing that. Every once in a while I'll get the itch to work on a new project, and always wonder if Java would be a good idea.
My hesitance is that I don't trust Oracle (and don't know to what extent they're involved nowadays), I'm not familiar enough with the ecosystem to know what is legacy crap to avoid, and I think it's generally seen as an uncool language, and I'm way too cool to be taking such risks.
Oracle has nearly nothing to do with Java. OpenSDK is developed by the Apache Foundation.
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.
