Before I started learning Java, I laughed at /g/ for bashing it. But holy fuck, it is the worst shit I've tried to code.

Personally I like Java but not everyone does.
Why don't you stop listening to /g/ shills and actually form your own opinion on something for once.
Why learn Java? If people stopped doing that it would eventually disappear.
Java is fine, some Java libraries have horribly verbose API, but that's the problem with the library developers, not the language.
Java's a pretty good language.
Why would you hate Java? What's wrong with it? I have coded in Java, C#, PHP, Ruby and i like Java the most.
Does C# have objects like java where you have to close/dispose the object after using it?

On topic, I find java really easy to use, especially with all the docs and info on the web.
>>53586989
>Any recommendation from the above list ?
Not on the list, but you could try looking into Scala in addition to those. Not for commercial purposes, but because it's incredibly fun. I've tried a lot of languages and there's always been some element that I didn't agree with, but with Scala I just clicked instantly. It's like somebody took the good things of all the languages I tried so far and combined them into one, getting every detail just right. Sadly it doesn't seem to see that much use professionally...
>>53586821String s1 = "op is fag"
What does that line do? Well the "op is fag" is actually an implicit call to a String constructor.String s2 = new String(s1)
This line makes a copy of the previous string and creates a new object for it.String s3 = new String("op is fag")
This is where it gets stupid, the double quotes in itself is a new string constructor, but since you're calling that inside a constructor the original string object created has nothing pointing to it and is lost.
Why does this matter? Java is garbage collected, right? Yes, but when new objects get created they get put in eden. The JVM doesn't clear eden until it has no more room to allocate new objects. Silly things like that will fill eden with garbage, and since garbage collection is expensive it'll probably make your code hiccup when the GC has to run.
Java should support primitive data types.

Do you have any clue what you're talking about?

There are much better ways to handle strings in Java. Once you realize that String is an object, that becomes immediately apparent. The problem is that you are treating it as a primitive when it isn't one.

Java can often be fucking great. It's the fastest non-native and garbage collected language out there, only beaten in speed by C, C++ and Rust, which are all native and you have to manage memory yourself.
If you avoid the "Enterprise" shit that the Java community has shat out, it's a great platform to develop for. Check this REST one liner from RapidoidOn.get("/size").json("msg", msg -> msg.length());
This framework also happens to be the fastest web framework in the world coincidentally (see pic). Elegant and fast.

>>53587665
Not much. Most of this thread is C elitists and clowns who actually haven't used Java. Object handling can occasionally be funny if you don't know what's happening in the backend. Garbage collection time can be an issue if you have HUGE amounts of data, although if you're doing that you can often set the GC to collect more aggressively.

>>53587915
>And as of JDK 8 Java includes functional programming as Streams
I agree that Java 8 has been a great step for the language. Much greater than when they introduced generics for example. I like Java a lot, but I also don't want to talk down its shortcomings: Functional programming in Java 8 still feels very much done "the Java way": Overly verbose if you want to do anything more than the simplest of tasks. That's why I like Scala so much, it has tons of syntactic sugar for almost everything and it's so flexible that you can make everything very concise on your own if it isn't already.
I really hope Java goes a little bit more in that direction in the future. Having a actual multi-inheritance system that's more than just interfaces with default methods would move Java forwards by a large amount, or maybe something similar to Scala's traits / mixins.
(which look great but are often slower).
I don't really see that as a problem. I'm not really a guy that doesn't care for resources / optimization, but a few percent slower performance or higher memory footprint wouldn't bother me all too much in most cases, if the code actually becomes more concise and maintainable. Which it does at lot when you compare Java 7 code to Java 8 code.
Will i like java coming from C++? Im taking a java course next semester
>>53587816
Note: It's not a good idea to just try and port a program to Haskell to get a feel for the language, since it's architecturally different from most conventional languages in a deep-seated way that requires years for somebody to fully master.
So whatever experience you are going to get out of trying to port game of life (or whatever) to Haskell is probably going to be unsatisfying.

I'm working on a Java library and I've been benchmarking it.
Using lambdas and forEach instead of a traditional for loop will give you a 200ms overhead. I'm sure as the JVM warms up the gap shortens by quite a margin but still that's pretty unacceptable for performance dependant stuff.

>>53588227
You'll like some things more and some less, I guess. I'm not too deep into C++ but from what I've seen, they're not all too different. Java has no true multiple inheritance but (IMO) a better standard library and better compiler errors. Also you have a lot less ways to fuck up, but you give up some control in return. I don't know if C++ supports functional-style programming, but Java does (although that was tacked on in a later version, and it kinda shows).

>Using lambdas and forEach instead of a traditional for loop will give you a 200ms overhead.
That's interesting, could you elaborate on what the benchmark is exactly and when the overhead occurs? What does the loop actually do when you compare it to a forEach? Is it a 200ms overhead of a single forEach call over a single for-iteration over the same collection? Do you use counting or foreach-style (Type t : collection) for-loops for the comparison?
>I'm sure as the JVM warms up the gap shortens by quite a margin but still that's pretty unacceptable for performance dependant stuff.
At least in the scientific community, nobody benchmarks without significant warmup. Benchmarks without any warmup mean nothing, the speed differences can be multiple orders of magnitude for a method that has not been invoked before or has been invoked three or five times in a warmup.

>Exceptions are a god damn mess
Assuming you mean checked exceptions, if you want a job done quick-and-dirty, sure they are shit. In production, a lot of the checked exceptions (I/O most of all) actually would have to be caught either way. By the way, if you want you can greatly reduce the boilerplate required for checked exceptions since Java 8 by writing a helper function or two that execute code in a functional interface and return the result, then hide any checked exceptions by encapsulating them in RuntimeExceptions.

You didn't "study it", you took an entry level course because it was required by your program. Otherwise you'd know that Java has been supporting functional programming since 2014 (although admittedly not as good as primarily functional languages)
>>53587244
> Java should support primitive data types.
What? You are a retard
>>53588892
>Memory often isn't freed, i've seen that happen many times
Now I'm genuinely interested. Which VM are you using? Most implementations intentionally don't discard every object on every GC run, though what you're saying sounds a lot more severe.
As for the performance, I don't have any number available on the machine I'm on right now, but if I remember correctly, it took less than five seconds to free 5-6 GiB worth of objects after a computation, which I'd call reasonably fast. Although I'd guess the data structures used in the program matter quite a lot. Also the program is designed to not produce a lot of garbage while the actual computation is running (it's not using the standard library).

>>53589110
>So it's still shitty
I'd say it's still better than Python's take on functional programming, and it doesn't support syntactic sugar for currying. That's irrelevant though, as your claim was that Java did not support functional programming, which is still wrong. The quality of the implementation has nothing to do with your initial claim.

I felt the same way you do about OOP when I was a young padawan, but then I understood it. And understanding it takes more than just learning the theory, it requires a radical change in the way of thinking which comes with time, experience and quite a lot of intellectual effort if you're coming from the procedural paradigm.
What most "muh C" faggots fail to understand is that not only is abstraction good, it's necessary at some point of business logic complexity, or you end up with unmaintanable pile of spaghetti that noone can comprehend. The key thing, however, is using the right amount of abstraction. Have too little and you end up with a weird OO-procedural mix that's usually the worst of both worlds. Have too much and you get an overengineered, overcomplicated mudball using every single design pattern ever invented just for the sake of it. What separates programmers from code monkeys is knowing where the sweet spot between those two is for a particular project.

Maybe if you do meme projects with objects like house cats and dogs. Most things don't neatly map into hierarchies.
Java has great tools, but the language itself is rough and overly verbose(and encourages the verbosity.)

confirmed ignorant

Just write C style code in C++.
You don't have to use OOP. I only use it for the quality of life improvements like parameter overloading, new instead of malloc, auto, ect...
>>53595315
>if you don't like Java then you are too stupid to understand OOP.
Class-based inheritance is dogshit that leads to brittle taxonomies that will inevitably fuck everything up for you. Prototypal inheritance is far more powerful and flexible and was one of the many gamechanging inventions to come out of Xerox PARC in the 1980s.
Of course you'd need a far better and more powerful language than Java to get to use advanced features like prototypes, but don't worry because Javascript is waiting for you for when you decide you want to upgrade to a big-boy language.
>>53595974
>javascript
>big boy language
HAHAHAHAHAHAHAHAHAHAHAHAHAHA
>>53595974
how literally retarded do you have to be to not understand inheritance? I understood it when I was 12, and I was (and still am) pretty stupid.
>>53596417
>Java 8
>finally getting lambdas
>Javascript always had them
Carry on trying to make your language better by implementing features that Javascript already has.
>>53596473
How stupid to you have to be to not understand his post?
It's not about not understanding inheritance. It's about inheritance being a very shit idea that doesn't actually make your code simpler despite it claiming to do so.
>>53596526
that anon pretty much admitted to be really stupid on his own comment so i don't understand why you're asking that...
>>53595974
There's nothing wrong with inheritance. It's people that use inheritance because they can, not because they need to.
They use abstract models that define a pattern, but never make use of that rigid definition in any way.
Example:
>I made an LeggedAnimal abstract class that enforces all animals have legs
Well what are you going to do with that information? Are you going to start subtracting legs if the animal misbehaves from the base class?
>No I just wanted to make sure all animals had legs
>>53596552
Or you could just composition.
>>53596552
that abstraction has a problem, not all animals have legs
>>53586749
Like when you laughed at /g/ for bashing it automatically?
>>53596611
All LeggedAnimals have legs tho
>Hurr fucking Durr Jaba!!!
>Ebytings an objeckt but not ebyting!
>>53586711
Python masterrace
>>53587983
...as the software runs Java bytecode, it continually analyzes the program's performance for "hot spots" which are frequently or repeatedly executed. These are then targeted for optimization...
Both VMs compile only often-run methods, using a configurable invocation-count threshold to decide which methods to compile.
from https://en.wikipedia.org/wiki/HotSpot
so yeah, a lot of code is interpreted as well
>>53588380
>(although that was tacked on in a later version, and it kinda shows).
desu C++ is full of that, there's all kinds of weird syntax because stuff was added later on
>>53595446
>overly verbose
seriously the worst thing I can think of for java
>>53596515
>likes javascript
>makes fun of any other programming language at all
>>53586711
JVM IS A CLUSTERFUCK, JAVA U SAY? WELL IN JAVA WORLD MINECRAFT IS A TRIPLE A TITLE AND IT FUCKING LAGS. THOSE FUCKING CUBES LAG, CARL.ITS SHIT BY DESIGN TO SELL NEW HARDWARE TO THE ENTERPRISE, ORACLE IS BACKED UP BY CIA. JAVA DEVELOPERS ARE IMBECILES/XML RETARDS.
Case closed.
>>53597523
That guy is right though. My job is in C, and I've also worked in Java, C#, and Javascript (and some lisp back at school) JavaScript is a fantastic freeing language. It's a great balance between imperative and functional. What's wrong with javascript?
But is it worse than CPP?
>>53598493
Dynamic typing combined with dumb coercion rules magnifies simple errors from typos that shouldn't compile in the first place.
Also having closures but no lexical scoping is retarded, although granted, like all of js's features it's due to be fixed in ECMAScript version 234957345897, due out any year now and sure to be fully implemented by every mainstream browser seven years afterward.
>>53598510
C++ isn't a benchmark for shittiness and most of the people who treat it as such on here are memelords jerking off over minimalism and trying to emulate their UNIX heroes by worshiping C.
Best thing about Java? You can develop GUI apps from your Linux or Mac machine while supporting Windows users. This means you can actually get paid while using your favorite OS. This has been true since the late 90's. This is partially why Linux has been so successful.
>>53587754
Haskell is a meme language anon.
I love haskell but it's not a language for writing large scale serious projects in.
Why did Javafags adopt JavaFX, /g/? Why didn't the brilliant light of Qt shine on Java as well through Jambi? What happened?
>>53598576
>implying dynamic typing isn't a fucking massive time saver
>implying you aren't jelly of the js truthyness
keep comparing object to null you pleb
>>53586797
It does GC works better than JVM bloated piece of shit
>>53599250
what's wrong with javafx, webview is pretty coo
>>53587424
No, he is a retard but his point is correct GC of JVM is a piece of shit and the creator of that abomination must be painfully killed
>>53587443
Of course no you fucking idiot
>>53595315
OOP is easy, but that doesn't make java any less shit. What's with all the painfully slow languages running in VMs? When will this meme die? I much prefer running my code on bare metal.
>>53599518
You mean websites should be written in native code?
All these inferior n misguided beings
learn MIPS n x86 for god sake
>>53586711
Wait until you fall for the python meme.
>>53599440
>horrible toolset, provides no direct integration between FXML and Java classes
>errors out the woozoo if something goes wrong, does not really tell what is wrong
>does not generate metacode for interface, is parsed at runtime instead
>no consistency in how "nodes" work, some resizable, others not, some need terrible hacks to resize properly
>layouts never scale well out-of-the-box
Need I list more?
The only good language is ocaml, desu. By this I mean that while scheme is a great idea, it only has (so shit they might as well be) unusable implementations; and ocaml is the only language even remotely in the same league. Moreover, it has several advantages over lisps such as the static typing, speed and native destructuring constructs.
>>53586756
Java isn't bad. It has some good libraries and it's that you don't have to deal with memory management. I've heard csharp is what java wanted to be and more though.
How do java GUIs easily and smoothly? I don't want to touch the code for individual elements unless I need to modify some specific functionality/form. I also want proper display size scaling out of the box with minimal effort. Haven't touched things since swing was king. Advice?
>>53588587
lmfao, good one anon. Hey could you pour me a cup of water without a cup, thanks.
>>53589193
this
>>53586797
>contrarians
C# contains something called Garbage Collection, that mostly manages itself. C++ is where you start doing memory management, and C is where you start ripping your hair out.
>>53596760
But you abstraction would force even snails to have legs therefore it is a bad abstraction
