Java is mounting a huge comeback 

Can't believe they finally updated their website. It really is the end of times. The hardest part of learning Java was never the boilerplate. It was finding the correct download.

I’m a Java developer at a bank and we still running Java 8. It’s only now that I’m writing my first microservice for java17… I don’t see us getting to 21 anytime soon.

I am not scared of AI, I am scared of Java making an unironic comeback.

I'm suprised how much I like Java when I started learning it for Backend Dev with Spring Boot. It's the language that actually taught me to use OOP (considering that it is basically forced), and the verbose code somehow makes it very readable for my little stupid brain, especially when it comes to others code.

thank you all for hating java, less competition for me, keep it up

Java Website went from 2000s to 2010. Huge leap.

Let's see if their website can also become "modern" 😊

If you want to know what Java will introduce three years from now, look at what Scala is doing now. A lot of Java updates are based on taking features from Scala and back porting them to Java, especially when the JVM gets changed to support Scala features.

Our school specifically chose Java as the first language taught specifically because it forces OOP on the user, and java is a great language for learning just that. I understand that OOP is not always necessary, and sometimes even overcomplicates things, but I know so many colleagues who've never really learnt OOP and fail to identify situations where it could really be useful.

I develop both using Java/Spring Boot and TypeScript/NestJs In Node you need to install a bunch of dependencies just to make a minimal working foundation for the framework. The lack of type safety introduces bugs, not in compile timae but in runtime letting the wrong variable type pass. There are multiple ways of doing things. There is no consistency. In my opinion is just a wild west ar this point. In Java everything is typed, avoids data type bugs by compile/runtime. There's only one way of say declaring an array. You cannot ommit return types. It's strict which makes it predictable. And you won't believe this. The code is actually cleaner and better to look at than TypeScript. Also Spring Boot is the most advanced framework you'll ever get. So Java is actually stable, consistent and solid to work with.

The one positive thing I have to say about Java (and thats 100% a personal thing) is that it helped me understand so many things in object oriented programming. I learned Java in School, learned advanced Java at university, coded in Java as my first job. Basicly any design pattern you can think of is implemented in Java, sometimes well, sometimes not so well, and you can certainly argue that there are actually too many design patterns. But still.. from basic inheritance to singletons, factories, dependency injection, annotations to more complex things like pattern matching, lamda functions... all this I originally learned in Java. Java is so unnecessarily complex that the only way to code in it is having a somewhat deep understanding of whats going on. Rather than javascript for example where You just bang Your head on the keyboard until something works. So yea.. for educational purposes Java is nice.

"Java is my all time favorite programming language.. To make fun of" The ultimate embodiment of "ngl he had us in the first half"

Kotlin makes me appreciate Jvm and Java ecosystem, The developer experience is very good, and I totally understand why enterprise software is written in Java. Less time reinventing wheels and more time getting work done. And the performance isn't even bad.

Never thought I'd see someone else say Java is their favorite language 😅 I love Java. I have affinity because it's the first one I learned and 20 yrs later, I still feel safer and more confident in my code when writing Java.

Java have put bread at my table for 2 decades. Fortunately in my current job we have the policy of using the last LTS so we are currently on 17 and planning for migrating to 21 next year

My favorite language continues to be and will always remain C++, but now that I've been working with Java and the Spring framework for nearly two years, I can say that I dig the Java ecosystem more and more. It's not as bad as ppl make it seem

3:15 I was looking at the screen and said to myself: I don't get the joke. After a little bit I imagine myself using that class and I realized there is no getter for that private variable "joke" I just get the joke when I found out I can't get the "joke" lol :)) Good one

As a Java Developer: please continue to hate Java with a passion, that means more open positions and higher salaries for me!

0:55 I think, it's fine to have "void". It's just like C. I'd also prefer if you don't need a function at all, but having one makes it slightly easier to refactor, if your main function will just become one of your main functions.

Java's syntax is admirably structured, adorned with informative keywords that empower developers. Despite the jests surrounding "public static void main string args," these essential keywords precisely convey vital information. Each keyword plays a significant role, and once you get good at it makes you feel in more control. As a C# programmer, But i love java(not Oracle) due to its exceptional organization and powerful nature. Not only is it simpler to maintain, but it also proves to be a reliable choice for enterprise-level software development that can stand the test of time for many years.

Java is a mid language, but the JVM and Java Ecosystem are incredible

As Bjarne Stroustrup once said “There are only two kinds of languages: the ones people complain about and the ones nobody uses.”

The spring framework makes Java so much fun to work with 🍃

For those that don't get why you need the "charAt" method on string in Java and can't directly index it, it is because string in Java are UTF-8, so it is not just an array of char, it is an array of bytes, because UTF-8 is based on unicode so not all char are the same size in bytes, so accessing the nth char is not O(1), it is O(n) as you need to traverse the string to find the starting location of the char, find it's size, and decode to unicode. Strings that handle UTF8 "out of the box" are harder to deal with, because they have railguards to prevent you from shooting yourself in the foot, but force you to write code that's going to work whatever the string is. strings with char out of the ascii table are a pain to deal with when not natively supported.

I learned to code with Java, completed my first project with php, tried to switch to c#, wanted to learn Javascript, but now i find myself working with java! what a life.

The Streams API and annotations are gorgeous. I honestly prefer Java much more than JS/TS for functional programming.

There are a lot of convenient shortcuts in IntelliJ such as psvm and sout instead of Public Static Void Main or System.out.println etc. I recommend looking them up for people who don't know because it will save a bit of time here and there.

"Put food on my family @0:38" . . . WHAT!!?

This might be a hot take, but up until rust, Java was unironically my favorite language to work in for most mid to large size projects. And the reason primarily comes down to its enums, which for both languages take on the power of variants. These variants make the strategy pattern, aka swappable implementations, a pleasure to work with. The scaffolding never bothered me, a lot of that was auto-generative. As an example if you type the keys "psvm" followed by a space in most java ide's your going to get a fully formed main.

Yes officer that's him. He updated his java

Ah, Java is fine. We've been updating our codebase from 8 to 17 for the last year. We have good templates to setup new micro-services and great company specific imports for boilerplate code. And there is so many annotations you can use to make the code look pretty. I started out in C# but java is kind of growing on me. Privately I usually use python though. For frontend I use whatever feels best at the moment, I kinda like flutter because of the cross platform easiness.

It may sound wierd, but I love how Java code is big. It makes me feel good when I code something (also I do get paid to create exercises for Java)

After spending 6 months learning java am happy to say I understand the memes

It is much more more that the syntax goodies JDK 21 will come with final release of virtual threads , which is the jvm equivalent for GO coroutines. Also there are multiple projects in place now in the ecosystem to make java more accessible for the cloud. Azul JDK released CRAC - i think- which allow java applications to have startup times in ms , Frameworks are focusing on AOT builds using graal vm, which can also allow applications to have smaller memory footprints and ms startup times. The JDK team is working on multiple refactoring projects for the language, major changes in the type system, objects memory foot prints. But God knows when this will ever finish 😅 Virtual threads took like 5 years in brewing and reviews

2:04 that line about the new Java website looking 10 years out of date instead of 20 got me :D

I love how, the more i know about code, the funnier your videos get

public static void main string args

besides the simplification of boilerplate and structured concurrency(loom), other features coming pretty soon (and some already usable in preview): easy native code interop with foriegn memory access apis and jextract (panama), less devouring of ram as mentioned in the video by storing objects more like structs (valhalla)

Java is a great programming language to learn. It might be the best second language for learners, since while the syntax is verbose, it is specific and easy to understand once you get the basics. Once you know java, it is much easier to pick up something like c++, since you don't have to learn the oo paradigm and memory management at the same time.

0:39 "because i need that boilerplate to put food on my family" hes not even feeding them, just putting it on them.

I'd love to see a SQL."delete from table where id=\{id}" to finally solve every problem of sql injection

You forgot to mention about virtual threads which is a huge deal! But only when the ecosystem will adopt to use it (so +10 years to wait :D)

As a dev who started with Java. I approve of this comeback.

For me, I learned Java in high school and python as a bit of a side project, python seems better for something quick and when you don’t want to worry about the stuff like decoding a video file into frames or something but if you need speed then Java is much better, it is also fun to make stuff in Java, still learning both of them so certain things are easier in either one , even “quick” programs I sometimes make in Java if it feels Easier and since Java is my first language, I will have a soft spot for it but it can be a bit complicated sometimes but at least I got chatgpt to teach me more about it,even if it is a bit outdated at this point

C++ and Python are neck and neck. That's like having a race where a short track speed skater is neck and neck with a pole vaulter.

Java or .c# may sound old but it has all the bells and whistles to write way more optimized and stable apps. Though I believe both Java and C# are very easy to learn still I have seen lot of people who finds it more involved. So all these folks go towards JS where entry barrier is very low. Initially JS gives impression its really fast to develop however any experienced developer will realize while it sounds quick to develop initially but kind of baggage it comes with will create huge issues later if your application grows in size. Simplest example I can think of is in 2023 NodeJS world has yet to settle on which ORM to use either PRISMA or Dizzle or something else where each of them having basic issues like performance, cold start timings etc. .C# and Java world has solved ORM thing from more than 10 years back. They are performant with rock solid stability. I have seen video from jack about React server components and Next JS server performance. A slow language like PHP was able to beat React server and Next JS by huge margin. Java and c# both beats PHP in terms of performance and stability by huge margin.

I'm not even a programmer or software engineer, but these videos are absolutely hilarious lmao. Keep it up dude.

Me leaving Apple live conference to watch your video..

Java's still at it, now introducing instant meme methods.

Minecraft, here I come.

I remember in community college, I thought I'd venture into computer science and my mom had me try a java class. And I hated everything, and I dropped out of them and told myself I'd never program again. But now I can read java and I like it 😅

1:07 « If we rename it to print, we get a perfect language ». Python, F#, Nim and Mojo: What about the semi-colon?

As a newly-converted Java developer, I'm delighted to hear that the language I've invested the last three months of my life in is still relevant !

The main advantage of Java is that it can track mistakes in real time, underlining things in red that arent allowed, and underlining things in yellow that might be a mistake. Most languages cannot do this, C++ can only do this at compile time, and Python can only do this after the code has already started (unless there's a blatant syntax error, such as unclosed parentheses). A lot of Java's limitations come from the need to continually support this system. That said, I rarely ever use pure Java, I usually instead use Processing Java, which modifies the java compiler ever so slightly, importing a bunch of libraries that are either useful or remove boilerplate (i.e. System.out.println can just be println, due to some automatically imported libraries). Also, it lets me draw on the screen, which is an automatic win for me.

Just did an assignment where I had to learn Java from scratch the day this came out. The system.our wound me up so much

As a C# developer, the modern changes coming to Java makes me happy too. It have been left behind for a long time. I leared Java in College, and it has a special place in my heart. That being said, choosing Java for a new project is a huge no for me. C# just does everything better these days. Also if i have to work with Jvm i will probably go with Kotlin.

Glad to see Java evolving, but im sticking with Kotlin. All the joys of a modern language and proper handling of nullable types.

Java is the new guy she told you not to worry about

I remember trying to do Hello World from scratch on an online compiler, I immediately gave up on the language and never touched it again

What people are forgetting is that the biggest pain point like boiler plate code can now be managed with Copilot and AI assistant code tools.

Java can be a nice language if you know what you're doing (and if you're using modern Java). However, it's dangerously easy to write really ugly and bad code really quickly. Just to clarify, this, of course, applies for all languages, but it's *ESPECIALLY* true for Java. (And a few other languages as well, i.e. JS and Python)

I'm going to be learning Java at uni next year, so this might be a plus

C# is enterprise and is not slow in adopting new features. Literally it should be used by startups before node

OOP design patterns are not unecessary my friend. When you look at huge backend projects in Enterprises, its these OOP patterns that help us understand the application logically in an otherwise chaotic codebase.

Java with Lombok is fine. you don't have to write any broilerplate. just type @Getters or @Data or whatever it was, and you have your getters and setters automatically, or if you write @Builder, you don't have to write constructors and you can use the builder pattern to make all your fancy little objects! it's so much fun :^)

You can get rid of the brackets, the semi-colon and even the file: groovy -e 'print "Hello" '. Groovy did this on the jvm almost a generation ago, before kotlin and swift stood on it's shoulders.

Amazing to see a new Fireship video!

A minute of silence of all the enterprise Java Devs who still run Java 8 or older because of customer demand who will not get to use these new features until retirement. I feel you.

actually just learned java and I like public static void (String args[]) when you understand what each word means it makes a lot of sense

I've been using all of the features mentioned in this video in my work for at least 18 months... in C#.

We killed all our java apps at work and running everything in c# best switch ever, and you dont need 1000 frameworks like spring just to do the basics its nice to see to get features from C# into Java, like the string thing

2:04 I Laughed so hard on that

My previous job I left a month ago just started using Java 11 for some apps instead of Java 8. But we also used Groovy, which cut down on so much boilerplate and gave String Interpolation. So life wasn't that bad.

Fireship: "And actually why do we even need a main function in the first place?" Me: *"STOP!"*

Tbf I haven't done any Java specifically, but I'm enthusiastic af about the whole "Everything is an object / class" kind of programming. Idk it makes a whole problem twice as easier in my head (making any problem into a set of relations between objects)

After years of C# just copying everything Java does, it feels good to finally see years of Java copying everything C# does.

yeah but all corpos who use java also make sure to use ancient java so it doesn't really matter

Imagine some big bank CEO occasionally watched this video then came to work next day and say an average Java developer Peter to rewrite all the big bank app to the new Java so it is more readable and cool😎

If you are pretty good with these in java. You know its the best - Annotation processing - Generics

3:24 I should point out that the meme is a bit harsh, because in this case, it isn't correct to treat strings as arrays of characters, they are not. In Java, the String class is encoded using UCS-2 aka UTF-16. In Java, a character (char) is a 2-byte type that used to represent a Unicode UCS-1 code point. However, that was only sufficient when the number of code points was less than 65536. Now Unicode has 1+ million. So UCS-1 was extended into UTF-16 which allows for some special pairs of 2-byte chars to be combined together into a 4-byte character, called surrogate pairs, to represent characters beyond the base multilingual plane. In these cases, if you just index a string as an array and get out a char, it might only be half the bytes of a unicode character, and you will experience bugs. Just see how many Java "reverse string" methods fail when using emojis. All this being said, Java String.charAt() is also busted for the same reasons stated above. Really, what we need is an object of a class that represents a "character" in a more abstract sense, regardless of underlying encoding or number of bytes in the buffer where it lives.

Just use c#

"or more accurately anyone who's forced to learn Java" xD There were a lot of exciting things happening with Java game dev in the early 2010s that made it really attractive as a kid learning programming for the first time who loved video games. Runescape and Minecraft were things to aspire to and you had Cherno making his first 3d game development series in Java. I remember trying to set up eclipse to work with LWJGL for a whole week.

1:05 also remove the semicolon, for ease of use

After 20 years of Java, I finally succeeded in moving to Python four years ago. I'll never go back.

I love the thumbnail for this one. That little guy has the perfect facial expression for skepticism.

"C# introduced top level statements in 2020 and maybe in another 10 years Java will get there too" Tbh I think there is a still a lot of jokes we can make

So Java was too hard to learn because of the boiler plate class definition? I guess so new programmers can just skip learning what classes are? Not that they typically would, it would just be boiler plate jargon just like "void main()". I don't get the logic since it's generated by templates anyways.

I had started my programming journey by learning JS online, it was a horrible time with only benefit that I learned how to sit in front of a computer for hours on end. I switched to C, and after about half a year of project-based learning in bootcamp conditions (Ecole 42 program), I picked up Java because it was in high demand among local employers. Half a year later I got my first job in software development. During my time there I got to work with Java 6-17, Kotlin, Groovy, Go, C++ and (regrettably) JS/TS in production. What I realized is that all languages have their own flaws and benefits. For Java, its wordiness is somewhat of a plus when it comes to enterprise development, because it's somewhat easier to understand someone's intent behind their code. The downsides are many, don't get me wrong: RAM usage, many many questionable decisions of the standard library, quirks or breaking changes when migrating from one java version to another. For the past year I've been coding exclusively in Kotlin in production (as well as using python to solve leetcode), and I quickly realized that Java, as baffling as it is, has much better and stable IDE support and Kotlin's frameworks are still years behind of Java's and you cannot just write pure kotlin in production 100% of the time. Recently I came back to Java (20) on a low-latencty trading project and I'm pretty happy with it, honestly. Also, having touched many build systems, I can safely say that gradle is probably one of the best builders out there.

In 2015 I took a job at an outsourcing company for a full-stack developer, for a banking group. The project I was involved was using: Oracle SQL+Java+HTML4 stack. In 2019 I left the company and felt way dumber than at the begining of the job. That's because at the start of the job I learned Oracle SQL, Java, Spring, Hibernate....but after I've learned them I only used like 1/4 of the knowledge and since the systems didn't upgraded to newer versions there was no need to learn new features. Also the security system was so rigid that we weren't allowed to install tools we didn't used for company's needs....

As ProgrammerHumor taught me, the quality and usefulness of a language is determined by how small the hello world program is. I mean this is the single most important feature in any language ever and it's especially useful in any real world application, like f.e. when working in a bank. That's why Java just now jumped up several levels! I mean yeah there are virtual threads and all that stuff in Java 21 but hello world is where it's at and what you'll use the most in any programming job

The memes were... kinda bad. I've been held hostage of this language for almost two years now and it does have some meme potential, but not as much as JavaScript or Python. Even the one about complex design patterns doesn't make sense, as no one with beginner-to-intermediate knowledge of the language would write like that. They would use lambdas or something lightweight like that. This rant was kinda sincere but kinda copium too. Long live the boilerplate.

I started in university with Java, and after several years of a break, am now at a startup using java17, and it's honestly great. Having intelliJ and modern java language features makes writing java actually pretty great if you keep things simple (i.e. use minimal inheritance and factories). Nullability and immutability (records need builders) are still the two biggest issues with java in my opinion, but so much else has gotten very good.

Trust me we will still run java 8 for another decade

oh yeah, I always knew the public static void main was the main (or maybe the only? public static void only) problem in java

"To put food on my family" 😂 good ol GW Bush

Kotlin has all that, more, and can be used on the Java 8 (1.8) JVM along with 2-way interop with Java code.

to be honest public static void main string args is still better than what python has

ALL HAIL JAVA, THE MASTER OF ALL PROGRAMMING LANGUAGES!!! I LOVE THIS VIDEO BRO!!! ❤

Am I the only one who thinks Java syntax is beautiful and is calming to my OCD??? 😭😭

“I need that boilerplate to put food on my family” Best quote from this channel
