Had to make a java interface for a COBOL program in development, which meant I was working close with the one who did COBOL full time, and ended up reading through the code myself. I didn't hate COBOL, sure it is a bit dated but definitely a valid option. The COBOL dev who joined the company around the same time as me and learned the language on the job ended up getting hired by a much better paying company after a year of using COBOL.
It was revolutionary in its time, but all of the benefits it once offered are now commonplace, and other languages exist that can provide everything Java offers + more. I have a Python-based project I lead at work, and we have type checking even though it's "duck typed" and all manner of safeties that were once associated only with statically typed, compiled languages. Of course, at the end of the day, you don't *need* one language or the other - all turing complete languages can solve all the same problems. Assuming a developer who is fluent in many languages, the biggest differences nowadays will simply be: whether libraries exist in a language to make it easier to solve a particular problem, how simple/maintainable the resulting code is, and the execution time. And the last one is increasingly irrelevant except in microcontrollers and big data since computers have massive resources. So I always suggest becoming a little fluent in 3-4 wildly different languages so that you can choose the right tool for the job when needed. Of course, most developers aren't fluent except in one *maybe* two languages, so that often ends up being the biggest deciding factor, and then they just pretend there was any pragmatic reasoning for deciding to use that language over another that would have made things far easier with all same safeties 😛
Might I add one more: The thing I like most about Java? Dynamic reflexion. Nobody knows what’s gonna break if they rename my class! Only I can understand my code. Most of the time. Usually.
I hate Java but dynamic reflection is actually useful and even necessary in some cases. For example if you're writing a Minecraft mod (in some framework like Forge for instance) you may need to change a thing at runtime or get some internal thing that's private. If you're only shipping the mod, which you usually are if you're working with a modloader, then your mod needs to use reflection.

We need only 3 frameworks to make a "hello world"
we use springboot and angular for it.

"i drink coffee for the effect" as a java dev this hurt
Java seems great for Sr. engineers who read more code than they write.
I love his sense for detail!
Taping the Java logo on the cup, just like most corporate java code is a cesspool of taped together nonsense.
I once had to update some Java code for a factory, found some interesting naming pattern like FactoryFactoryProductionBuilding, AbstractFactoryFactoryStorage, ...
you gotta have a factory for your factories, how else you gonna instantiate them
@@gundabalf I just use a static factory Method to instantiate my BuilderFactoryFactories. Simplicity.
Not true at all. I worked on an enterprise Java project once. Only took me a year to understand what it was doing.
@@sinistar3198 worked on a project which wasn't that huge to begin with
Still dont really understand what I was doing when I left in a lead role a year and half later - java codebases are an eternal mystery
POV: You've mentioned Kotlin to a hardcore Java developer
Loving the videos.. They are hilarious.. I waited for the 3 billions devices mention on that... Next time maybe (Java from a junior?)
Hey, I was part of a team that built an online banking system for a major California bank. We coded in Java on Windows 2000. Tested on Linux, and deployed to IBM Aix Unix. What other language could do that without any code changes?
To be honest not so many devs are working with current version of Java. I think 11 is their maximum. The problem is many are just working with framework spring and they don't really know java . And companies still don't hire juniors
So seniors don't know Java?
I was going to ask if you have a C# video, and it's on the right side in the suggested videos lol. Just came across your channel yesterday and love it. Great videos, thank you for the laughs!
As a corporate Java/Spring developer, I can confirm this is accurate.
1st month on the job with Java in the finance industry. "I drink coffee not for the taste, but for the effect."
"I drink coffee not for the taste, but for the effect" Relatable
I lost it at "let's start with a test suite".
if you change 10% of this video you also have an amazing C# video.
Honestly not that many bad things to say about Java. It was one of the first languages I learned. It's pretty great. Gotta catch eveything, it's like baseball!
*excited* Have you heard of Kotlin?
*unexcited* yeah we actually use plain java
hahahaha
i like the part where he's just looking at the monitor going "heh heh heh heh"
"You have to catch everything, like baseball!"
The 30.5 years joke killed me 🥲 so true
"i spend my time writing exception types."
Hard hitting!
"because its safe, portable, maintainable" ok that got me
ok james watson, very cool
"Do you know what kind of coffee this is?" - Pun sooo bad its good
Don't know what I just watched but somehow my day feels complete now
I like how he repeats the same thing over and over again just like everything in java.
Dude, every time I'm writing unit-tests, this video comes up to my mind...
you are such a HERO and i love this video. I SPEND MY TIMES WRITING EXCEPTION TYPES
"Do you know what type of coffee this is?"
I was about to say "Big decimal"
He should have added "Impl" to every 5th sentence. And like a semi-colon for wall art.
should have opened eclipse on the backgroung
Portability: as portable as anything needs to be within your IT department's domain.
JPA: I'm not afraid of you anymore! Jmeter: I must break you.
I will say this - the Java standard library is fucking nuts. I almost never have to leave it to write complete applications. Which is good because Maven is a fucking nightmare.
The white IDE fits pretty well with my preconception of how a serial Java developer works
I had to compare two BigDecimal fields last week while also making sure the 2nd object was of a class that had them, the if() condition was longer than this comment
took the whole thing to get to the best punchline. We definitely love our syntactical sugar!
"Big Decimal" - I felt that
Big Decimal
I was going to upvote but the number of upvotes is 420... seems appropriate for this video. BigDecimal!
Did not know that Leonardo Dicaprio is also a badass Java developer.
Hahaha, the only joke that really made me laugh. I can understand geek jokes, but they don't make me laugh, but developer jokes are fun.
i remember all those terms(Gang of four, design patters, portability .... etc etc ) 15/20 years ago in the Bruce Eckel book on Java, it was the thing to know at that time, a lot have changed, now it's all about Python, and in few years Rust will be what Python was few years ago the THING to know
No, Rust will not replace Python. Rust is supposed to replace C, and it might, or maybe not.
Python has replaced Fortran. If anything is set up to replace python, it's Julia, but I don't expect that any time soon.
Java has replaced COBOL. It was supposed to replace C++, but it failed spectacularly in that regard: C++ has replaced C++.
C# was supposed to replace Java, but instead C# is the new PL/I. Kotlin is replacing Java.
the day that those languages are going to be unused we will have AI that write it for us and we wll be unemployed, don't worry about using any language for now, we are probabily the last generation of human coders
@@sharkpyro93 AI is just a trap term for stupid people, the only thing i believe in is machine learning, it's impressive if you read some books on it, but it's not magic, it's like the other guy said AI it's not artificial(it's made by humans) nor intelligent, it's most relies on human intelligence to recognize statistically some patterns to reproduce, and of course the blazing computing power, if there will any day that AI is a real thing like you see in Prometheus movie for example, that would be in hundreds years from now, probably in a thousand years if humanity is till on this universe, maybe we will blow out ourselves before that, we still don't know mostly 90 percent at least how the brain works, how it get's it's energy given how infinitely complex it is, it's not just sugar and carbohydrates, still didn't explore 99.99999 percent of the universe, that is the things i believe in, we don't know shit .. like one philosopher said, the time it's take you to read the Odyssey 2000 years from now is exactly the same as now, even will all the technology we have there is infinite amount of things to explore and know
@@KaoukabiJaouad i wasn't referring to AI as Sci-fi Ai, but more like code that write code, (which already exists btw), the next generation of coding languages are going to be most likely declarative, take SQL as example: you tell him what you want to get, not how to get it, an human input is obviously always needed
@@davidwuhrer6704 Java was never meant to replace C++ lmao, it's fundamentally impossible because of the JVM vs bare metal execution.
These videos are great. You have a good ear for obnoxious language. So funny.
Thanks for making fun of it, i feel relaxed
This whole video would just be me screaming hashmap
