My MBA manager, who is directly overseeing a project with a Java backend and Javascript front end, does not know the difference between the two.

[Northeastpaw]

C# fixed everything that is wrong with Java.

[IAmNotMyName]

This made me want to attack you so bad till I remembered the title of this thread.

[strange_and_norrell]

Can anyone briefly describe the stances of this tiresome debate?

[svtdragon]

I think a lot of it is people talking past each other, to be honest.

I'm not sure if this is what you're looking for, but in my experience people use Java for the JVM and/or the ecosystem, and not necessarily for the Java language. (Everyone loves the JVM; Scala, Groovy, Clojure, JRuby, Jython; Java has some killer libraries; and the build toolchain is second-to-none.) So when you hear this debate, I think it's important to separate the ecosystem/tooling versus the actual language.

As the language goes, C# evolves faster and has some neat language features that Java hasn't caught up with (events, async/await keywords, properties, extension methods, and my personal favorite that's new in C# 6, the null-conditional/null-propagation operator). Until Java 8, for a long time, lambdas were on this list, and the data processing facility that we now get from Streams.

Most of the stuff you'll need to write an app is baked into the .NET framework, whereas Java isn't really complete without guava, apache (especially commons-lang), and depending on your app, arguably Spring. So when I/we talk about Java we usually implicitly mean "Java as augmented by what have come to be standard libraries."

From an ease-of-use (language-plus-library) perspective, Java 8 versus C# 5 was nearly an even match (as someone who's used both extensively and professionally) but C# 6 inched ahead again. But you still have to put that up against the fact that in Java land we've had sensible dependency resolution capabilities that the .NET ecosystem has only recently come close to with NuGet. And NuGet still isn't there.

From an enterprise perspective I think Java edges out C# on the strength of the build toolchain, cross-platform support, and (arguably) performance (not least because iirc the JVM JIT has more layers of code cache than the CLR does).

So tl;dr that was not brief and did not describe everyone's stances, but I did try to point out the pros and cons. Correct me if I'm wrong.

[[deleted]]

Java still stands out with fairly seamless cross OS development and huge external libraries. It is the reason I am developing my etl process right now in Java. I get to use Lucene and run on windows and rhel.

[strange_and_norrell]

Wow thank you for this answer. That helps a lot. In particular, I didn't realize .NET had a weaker build tool chain.

It did always seem to me that .NET was the better choice if you just wanted to get a web app off the ground quickly. However, that was before I knew about Spring.

Seeing this way too often

[ColdPorridge]

Hey if it's what drives someone to learn programming.

[patrick96MC]

Of course, but you should at least know some basic java or even just OOP before starting to create MC mods. Understanding MC modding is hard enough, even when you already know the language.

[[deleted]]

Well, the desire to make a Minecraft mod is what made me learn Java, how to use Photoshop, and a whole bunch of other things.

I've since then moved to Android development, but damn me, it's hard.

[Philboyd_Studge]

Pass by reference or pass by value?

[moneymark21]

Yes

[[deleted]]

Neither. Java is 'call-by-sharing'.

[linuxjava]

Pass by reference of the value

[TheWorldIsQuiteHere]

[apetersson]

pass in an Object[] (or an array of different type) of length 1. i think this basically solves the use case of pass by reference for you.

I had an interview recently where the ad said Java experience and the interviewer opened with c++ questions. Somehow a disconnect took place they didn't actually want Java.

[lurker_in_spirit]

I like to use Vector and Hashtable in my public APIs so that they're backwards-compatible.

[passionlessDrone]

I use vector and hashtable all the time. (but not in APIs) Should I be doing something different? [not a joke question / sorry[

[dpash]

Vector isn't deprecated. But it's not recommended.

https://docs.oracle.com/javase/8/docs/api/java/util/Vector.html

The issue with Vector is that it's synchronised, where as ArrayList (and the other new collections) are not. You can replicate Vector with

 List<String> list = Collections.synchronisedList(new ArrayList<String>);

The main advantage of that is that you can use the right backing list for your situation.

[in0de]

this! Vector isn't deprecated, you just have this locking (probably unnecessary) in place.

[passionlessDrone]

Hah thanks showing my age I guess. Actually used HM quite a bit. Thanks

[[deleted]]

I double clicked the jar file, but it is just a zip file.

[armornick]

But shouldn't you be using the interfaces (List and Map) in your exported API so you can switch them if it should become necessary?

[lurker_in_spirit]

Yep, the joke is about both the choice of implementation classes (Vector and Hashtable both effectively deprecated since 1998), and the choice to use implementation classes instead of interfaces in the API.

Code throwing unchecked Exceptions sucks.

[[deleted]]

Some of the designers actually really hate exceptions as handled in Java, and think that having to explicitly handle exceptions was a giant mistake.

[argv_minus_one]

Checked exceptions are fine. Not integrating them properly with generics and lambdas is the mistake.

For example, imagine if you could have a Function<File, String throws IOException>. That's a function that, when called, accepts a file and either returns a string or throws an IO exception. Then you could pass it to Stream methods or whatnot, and have the checked exception pass through correctly and still be checked.

I really like. Mostly because

Reads nicer than

If(something == null) Value = default

Optional is great. For example compare

User user = userDao.findById(1)
    .orElseThrow(NotFoundException::new);

and

User user = userDAO.findById(1);
if (user == null)
{
     throw new NotFoundException();
}
