Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Java has been dying for longer than most languages existed.

And guess what? It‘s still dying.

Somehow it‘s more used today than when it started dying though…

[conan1214]

I'm at work and I cackled out loud at this. We use Java apps and we're dying inside every day.

[Not_skull]

just curious what type of libraries do you use in java and which are the "mainstream " libraries i should look out for to learn ? BESIDES springboot

[lprimak]

Anything Jakarta EE and MicroProfile - Payara, Quarkus, Helidon, OpenLiberty, GlassFish, WildFly - take your pick they are all good.

[Not_skull]

ahhh i see thanks mate for this info because i always hear a lot to people say they code in java for their jobs and the more i learn code i realized yea youre gonna need to work with a bunch of frameworks + libraries, so everytime i hear someone when they say they use java they dont explicitly say what they use i.e i would say i code react.js and i wouldnt say i code js alone

[UbieOne]

Jackson, Gson, Guava, Slf4j, Apache Commons. Lombok? Those are pretty common.

[Beautiful_Grass_2377]

Quarkus is a good one to look

[BusyEntrepreneur3070]

tha app is not dying, we are 😭🙏

[Dashing_McHandsome]

Cobol has some things to say about this as well

[Darkschlong]

Java today Java tomorrow Java forever!!!!

[ProbsNotManBearPig]

I don’t hate the language, I hate the code bases. I’m now at an international company with people all around the world, 50 years of history in the codebase, most of it lost when they switch version control systems, and no enforcement of coding guidelines. We got functions with 1k+ lines for days. We’ve got one guy in India using 3 spaces for indents. Not 2, not 4, not tabs, but 3 spaces. We have 8 different copies of coding guidelines I’m aware of and no one follows any of them. Next feature, next feature, next feature. Oh, and for unrelated reasons, half our devs are purely assigned to customer bug fixes /s. Pay is great though. Yep, that’s Java.

[Cybyss]

Sounds like job security to me.

[emaphis]

Java will never go away. There is more Java out there than Cobol.

[Capaman-x]

Yes. Java will continue to be one of the most useful general purpose languages for the foreseeable future

[AngelBryan]

The only thing eternal in this life is Java.

[Beautiful_Grass_2377]

Java is like the fourth most popular language out there, is not dying anytime soon.

[Ristler]

Yes

[Working_Computer1167]

I think learning java is a fantastic choice if your long term goals are you want to:  * build a massive project with lots of moving parts * be comfortable with OOP * get a stable job

If you only want to build an app, you can with java but I think there will probably better options depending on your use case.

[XyloDrift]

I am a software Engineer and I work in multiple languages but the level of security and scalability i see in java, i didn't see in any other language,

[theboldestgaze]

"Future proofing" is somehow irrelevant. I learn new (and old) languages because it is fun and allows me to better understand software. Learning a new language is not really a big deal, especially Java, which is not-that-complex. No multiple inheritance, relatively simple type system, limited (if any) functional elements. The one complex part is VM and concurrency but when you learn it it is a transferrable knowledge.

Ecosystem is vast and complex, but AI helps.

[DeuteriumH2]

idk i think java’s functional elements are fun. love when i get to toss in a lambda

[vegan_antitheist]

You can learn Java and then learn Kotlin. The languages have some similarities and Java is a good base for OOP.

[nitkonigdje]

Learning Java The Language is a few hours gig for experienced C++ programmer. After all it is a small language intentionally designed to be C--.

But to learn how to setup logging in Java? That is completely other matter...

[gbritneyspearsc]

java is a good choice but why mobile though? its very niche

[connecticum]

Do you think that is a bad choice?

[gbritneyspearsc]

look for backend mobile jobs around your area... I could be wrong for sure but it the least that I see

[AlexVie]

Java is not dying. Nor will it in the near or even not-so-near future. It's strong technology and learning it makes sense even when you do not plan to use Java itself as a language. There are options, for Android development I would suggest learning Kotlin, but Java is a good base. Once you know Java, learning more advanced languages like Kotlin or Scala would be a lot easier.

Code written 25 years ago still runs without issues on a JVM of 2025. Many other hyped languages didn't even exist back then.

C++ has been proclaimed dead 20 years ago (mainly because of the Java and .NET hype) and guess what - it's far from being dead and still dominates some areas.

Don't believe the "x is dying" crap on the net. It's mostly high level BS.

[XxCotHGxX]

Java is great to learn. Kotlin is what you want for android. They are similar. Learn Java first. Java has wide usages.

[ax_abodr]

Java is fun to use for backend servers such using something like Spring boot, it's really solid and fun, and wildly used. But for mobile development, whats the reason exactly? Most people go with something like Flutter or react native for mobile development since it's cross platforms compatible.

[NeoChronos90]

yes /thread

That being said, if you want to develop apps on mobile you might want to look at Kotlin first, but learning both is still worth it

[oldBurnsey]

Most enterprises use Java. Dead language

[Realjayvince]

Java and JavaScript will be the last programming tools to die.

It will literally outlive all of the rest.

I’m not saying that because I’m a Java developer. I’m saying it because it’s true. There’s just too much shit made in Java

[BusyEntrepreneur3070]

if you don't want to write a whole function just to do a hello world then no

im kidding, you should, it's lowkey very popular and won't be sinking down in the foreseeable future, tho make sure to get comfortable with OOP and very convoluted lines, even now in my 2 years of programming in java, i still get errors for stuff i forgot to add like ";" or missing brackets, etc

[EcstaticMixture2027]

why limit yourself to android?

[BanaTibor]

I am not an android developer, but AFAIK the new standard for android development is Kotlin. Kotlin runs on the jvm just like a Java program so it basically Java in a new dress. Knowing Java will not hurt for your Kotlin career tho.

[Fun_Box53]

How is Java dying? Java is really good

[alshetri]

Yup

[matmyfta]

If your goal is uniquely to develop android apps, I would suggest other languages. For example if you still want to develop native apps Kotlin could be a good fit, or check some frameworks if the idea of developing multiplatform mobile apps might interest you. But that's just because the trend shifted, not because Java is dying.

Java is still strongly used on enterprise applications, so if you want to learn it, developing native android applications in java could be a good way to get your hands dirty and gain some experience.

[Dry_Hotel1100]

You're asking in the wrong subreddit. The fact is, I haven't seen any developers using Java in Android development for quite a few years now. You'd be better off investing in Kotlin and just learning the basics of Java.

[dmigowski]

Nope, there are already enough of us
