Java in 100 Seconds 

"public static void main" These words together are legendary.

Ok ladies and gentlemen, I am ready to make Minecraft 2

Java is absolutely incredible. I have chosen it as my first programming language and never got past making loops. I love it.

Following the "logical sequence", the next in line is Kotlin in 100 seconds

Correction: write once, debug everywhere. That's what it truly means for developers. ;)

"Congratulations, you just built an enterprise grade application"

I have been using java for ages, but still watched this video in anticipation that this brilliant soul would say something new in 100 seconds that I would have missed in years.

A useful tip Since Java 17, you don't need to compile the class files anymore Just pass them directly to JVM, and it will take care of the compilation for you

1:15 "The class is required to have a main method" - well, it may create some misconceptions, because not _every_ class is required to have a main method. It could be rephrased to "Every program is required to have a main method in one of its classes".

keep it up with the 100 seconds of code series! everyone is liking it.

This will probably be the only liked Java video in my life.

Java actually my preferred language to understand OOP concept

Now that you've done Java, you set the ground for Kotlin in 100 seconds! Kotlin is a JVM language that runs in the Java ecosystem but much more modern and safe (mostly by null-safety). It's similar to Swift in syntax and can be used to develop mobile apps as well (Android's official language is Kotlin, Kotlin with Native compilation target can target iOS too).

The required like count makes me think that he might not wants to do a Full Java tutorial :D

Java, the beginning of everything for a lot of us

My first programming language, absolutely love it.

At 38 years of age I decided to transition to being a software developer and I love this video and this series. So keep it up! TBH, this 100 second clip took me over an hour to decipher. I ask the most basic of questions, like what does a "class" mean, what do the curvy braces mean, why are there no clocks in my room? Keep up the great work. The seasoning of humour is a much appreciated touch that makes it easier to digest.

Literally searched "Java in 100 Seconds fireship" yesterday, you keep making the perfect content!

- what words were written the most in the world? - "i love you"? - No, it's "publis static void main(String args...){}"

Learned this in school and then never learned it again. Looks very powerful. Amazing video as always.

Lets pump the like button and so our boi goes out of his comfort zone (JS land) 😂👌🏾

Great video! There is so much more in the modern java specially in the latest JDK 17 LTS and such a big ecosystem(and much more to come). Hope you explore in the near future!

Do kotlin in 100 seconds next pleasseee

I dare you to make Assembly in 100 seconds.

literally the best programming series on the youtube

Java! First programming language I learned.

Great short as always. Please do a full tutorial on Java. Would love that.

Cool. I'm taking a Java course right now and this toom me back to the beginning when I thought everything was fun. Anyways, I'm super looking forward to the full tutorial!

Great video, got my second Java job today. Looking forward to more!

Please make a video about the research you do before making the actual video. You always publish the things we need 💛

With recent releases, you should also be able to run a java file directly. I am happy to see Java implementing modern language features from time to time. I'd love to see a sequel to this with "Kotlin in 100 Seconds" which is a modern and safe (mostly by null-safety) language that also runs in a JVM. There are additional JVM languages like Groovy and Scala. And the best thing is, that they interoperate quite well in a single project.

Bro, You are literally my hero. You are exploring everything. Let's connect somewhere, I wanna help you in exploring more technologies.

well thats unexpected but i kid you not i was thinking: i dont think i would see fireship making a video about java plz do C# next

meanwhile KOTLIN: let me replace you

This is literally what I asked for like a few days ago! Thank you! 😃

Hi! I love the "* in 100 Seconds" series and would like to suggest "Lisp in 100 Seconds" and "Kotlin in 100 Seconds" since i couldn't find anything on these languages in your videos and would realy love to see what you would value most in these languages!

Tensorflow in 100 seconds, next please! You're a true gem for the development community, no doubt!

Great video! C# in 100 seconds next perhaps?

Wow, this day has come. The video about Java :) . It would be great if you could post more videos about backend\devops technologies.

1 hour since the release of the video and it's in RU-vid's recommendations. Great job !!

Started in python before jumping to Java. Always been one of my favorite languages and always will be. Now I focus on JS for it's versatility on the web

Yooo, Java got a 100 seconds video! Since that's the language I started my programming journey with, it has a special place in my heart. Thanks for the good stuff, Fireship, I'll be waiting for a full tutorial 😊 .

Thanks for adding labels to that utilization chart!

The fireship 100 seconds background music sounds like a really cracked remix of skype call sound 😂

Love you fireship, always wanted a 'Java in 100 seconds' but was afraid to mention cuz it seemed like the community here consists of more JS fans😅

Thanks for the video, added Java to my resume

Just to be clear File name and Class be same is only required if the class is public hence there can only be one public class per file. Great content.

Thank you, all of your videos are really awesome and well explained!

My first programming language. I’m absolutely in love with Java

There needs to be more excitement in the community about Java. Its a shame that there isnt anything new and exciting in Java because the world needs more Java devs!

Best channel. Informative and concise.

Thanks! I have been waiting weeks for this.

Scala (or other JVM languages )would also be great

I think he forgot that you don't need to compile(javac) anymore. Since the latest version of the JDK, the "java" command auto-compiles + runs it for you.

100 seconds - that's very well condensed! :)

These videos are really cool if you want to decide on selecting a new language

Java devs: old is gold Rust creaters: we are 4 parallel universes ahead you

Is anyone else learning Java, but while learning you come watch this video? Then everytime you get further in progress you come to this video to see how much more you’ve learned?❤️

We need the Java Tutorial!! I think that for your channel's thematic (web) it would be nice a Spring Java tutorial (with prime faces)

Let's go Good job guys on 10k+ likes I was always hoping a java course from him.

There are literally 20 minute long tutorials that I've learned less from holy shit. Thank you Fireship, I'll one day owe my job to you.

Of all the programming languages I’ve used, I find javas syntax to the most readable and easily understandable

Was waiting for this for so long. Waiting for more on java, though

Great vídeo!. I'd like to see C# next :)

Would love to see Java compared to .Net 6. Personally, I feel like .Net 6 stomps Java in a lot of ways.

You set the bar pretty high to ensure you don't have to do a full tutorial on java 😂 Beyond one hundred seconds on Hadoop would be interesting though

I have been learning java for almost two years now and reassure you I become better and better day by day

The only video that can show JAVA as something cool! Create 40+ lessons JAVA course in this style and you get $100K easy, simply because currently everything is boring and gray at a JAVA courses landscape.

hahahahahaha I just wish there were enough trolls out there to get you create that tutorial :P In all seriousness, I have a fond memory of Java, it taught me almost everything I needed regarding typed languages without the hassle of dealing with pointers.

Ok then, .NET / .NET Core / .NET Standard / .NET Framework / Mono in 100 seconds?

It'd be cool if you compared making an app using a traditional Monolithic framework (like Rails + Hotwire) vs the now common Frontend app paired with a backend API. I ask because there seems to be a bit of a resurgence in monolithic frameworks or combining "old school" ways with modern tech

Im thankful my trainer chose java as my first lang. And now its quite easier ro migrate on other langs.

You could do this with C# as well. Almost the exact same thing. Maybe there's more and more syntactic sugar added to C# than java, but in general, very similar.

I was a Java developer but due to demand I had to move to javascript...from past 6 years didn't wrote a single line of Java 😩😩

My first encounter with programming was C#, then we did a bit of Pascal in high school (ew), then Python, JS, PHP, C++ in college. I've been working as a Java developer for the past 3 years, and even though I hate some things about the ecosystem (fuck Hibernate, seriously), I still love it. It's just very simple. Verbose, true, but that's the price you pay for readable, self-documenting code (if written well of course) with a good type system. It's pretty easy to maintain, there are tons of resources, many options for libraries and frameworks. Kotlin is even better, as it fixes a lot of issues in Java - for example null safety, also kinda has pattern matching using "when". Very nice. I would definitely recommend it as both a first and a primary language.

Nice detail starting the bytecode on the .class file picture with CA FE BA BE, which is actually how it is IRL!

At 1:50 String brew() returns an empty char with single quotes (return '') instead of double quotes for an empty String (return ""). But I have to say that this video is just a beast at explaining Java in 2.5 minutes.

I love how he makes java sound so short and simple 😂😂

Finally my language comes.. Was waiting for this..

finally! you create about java! (it’s my first language to learn)

could you please do a c# video ?

If we're doing JVM languages, Clojure next? 🤔

Great videos as always. What is the extension you use to the color scheme??

This man will change your perspective towards everything

Java developers after learning Java for 3-4 years be like :- 😶

I used to love Java, Until I found Kotlin 😁

Java Language helped me a lot in my Wireless ECG signal Final Year Project via Bluetooth module, Arduino & AD8232 ECG Sensor !

Seriously, how do you not have 1,000,000 subs!? Great content please keep it up!

0:16 SUS!

Java in 100 seconds? You've gotta let it steep longer to get the flavor 😎

outstanding ☑☑

Ah finally. Was waiting for your Java in 100 second

1:14 Eh, almost.. Any public class in a file should match the filename..

Guess we will never get the full java tutorial

Hi man! I accidently became the 10,000th person to like this, I have screenshots to prove! That's awesome feeling! Long time follower of your channel, great work, awaiting full tutorial, specially spring development.

Learnt Java at school, never knew why I had to install JRE on my PC. Just by now, I understand how Java works. Teachers should give this video first before teach Java :D

More like "Write once, Ruin everything"

C# is Java, but better

'public static void main' that sums up Java really good. You need to write a lot of boilerplate code to get anything done, or at least that's how I remember it, I have not written a line of Java since Python 2.5 got released.

As a freelance i don't like java but i like the way you teach genius thanks .
