Is C# Better than Java?

[@battletremor]

I have just started programming in c#, It was very easy to learn and I could put my logic into code effortlessly. So c# is a better choice for me, this video helped me understand more about c#, great work 💯

[@GavinLon]

It's my pleasure. I'm really happy that this video has been helpful to you :)

[@aweklin]

The differences are the reason I stick with C#. Though, I started with Java but more mouth watering features of C# made me stick to it. C# wins almost everywhere if objectively compared.

[@GavinLon]

I totally agree! C# wins for me too! Thank you for your comment! :)

[@femidaniel]

My Experience,we once had an airtime vending project built with Java and deployed on wildfly,,@ peak demand periods it would suddenly freeze daily,when we moved over to another one built with C#, i took time to note we only restarted that application twice in a whole year,i have a great Java Dev as a friend too,but Microsoft with DotnetCore and now Blazor will always be my preferred choice and serious wide margins,Thanks for the detailed post,great work.

[@GavinLon]

You are very welcome! Thanks so much for sharing your experience with both Java and C#/.NET. I will certainly not be moving over to Java any time soon. I'm very happy sticking with .NET and C# :)

[@MegaJohn144]

I programmed in Java for about 10 years, but I never fully got it. Java and all its tools seemed clumsy and disjoint. After retiring, I taught myself C# and Python, and I much prefer them. I cut my teeth on C and C++, so it is a natural choice.

[@GavinLon]

Yes exactly, why make life harder than it needs to be? :) Python and C# are so much easier to learn and apply in my humble opinion. My first language was C - definitely a great first language.

[@LE8271]

I believe one aspect is missing from the summary. It is the fact that .net core was created containers and Internet in mind. When it comes to containerization it just kills Java hands-down. Look at the size and the performance of a Java based container that tells everything.

[@GavinLon]

Great, yes that is a useful addition - thank you!

[@Anbu_Sampath]

C# has nice language features when compare to Java, but C#/.NET mutliplatform target came bit late when compare Java/JVM. Now unified .NET is big move and attract more devs.

[@GavinLon]

Yes, I totally agree with that!! Java is way ahead at the moment, because (as you have stated, C# and .NET have only fairly recently become cross platform and unified) but the gap is closing :) C# and .NET is becoming more and more popular!

[@nickbarton3191]

And C# now has extensive FP support, I predict that it'll take over Java's 3rd spot.

[@hammeedabdo.82]

My personal opinion is that C# is better, and it should be ranked after Python and JavaScript. However, I don't know why I always see Java ranked before C#?

[@GavinLon]

I honestly and objectively cannot think of a better programming language than C#. I also like Python and JavaScript, they certainly have their place but Java could probably be seen as the most similar language to C#, and in my humble opinion C# wins hands down! :)

[@igorthelight]

They are ranked by popularity - not on how good they are. Typescript is better than JavaScript but it's rated lower ;-)

[@michel_dutch]

The best language is the one that pays the bills. In my case, that would be Java.

[@GavinLon]

I totally agree with you! Definitely pay the bills as first priority :)

[@michel_dutch]

@@GavinLon I'd like to add that I do appreciate C# in that it provides an incentive for Java to improve, the same way that Groovy and Kotlin did. Java is becoming an awesome language. Well, at least if you started with Java 6, that is. 😊

[@lufenmartofilia5804]

Well that is how I ended up with java too but to be fair java or c#, you can't go wrong with any of them 😁

[@lufenmartofilia5804]

I code in both in a daily basis and I prefere personally java. The reason is the ecosystem, the language doesn't bloat with keywords and hide logic from the user. Java is straightforward easy to read, verbose (which is a good thing imho, as it make crystal clear what is happening). Further more a lot of important/ highly reliable tech I work with (Kafka, hivemq, apache beam, elastic search etc) was buildt in java with java in mind. While they do sometimes do have a c# client, they mostly feel like a second hand citizen. Furthermore, c# dependency often require some form payment (example if you need to do an advanced ETL pipeline that require to process a big amount of data, you end up using efficient data format like .avro.) while c# can work with it, free libs they have are far from as good as java. Not to mention virtual threads that is a god sent. Now everything is not pretty on java side too. Java is basically only usefull for backend / embedded environment which make it a very specialized language and not as versatile as C# that does : gaming, backend, frontend, desktop app etc. An other thing is that migrating legacy java (java 8) to modern java (21+) is a pain in the ass. Too much jobs require to work still on java 8 because of the migration problem / cost. Also java mentality in general is all about being functional and stable and less about rushing behind the new flashy trend or methodology that get popularity outside (95% of case) of the real world usage. This can be a plus or a con based on the envirronment. But usually this can be solved by basically using kotlin.

[@GavinLon]

Thanks so much for this detailed feedback! :)

[@Ewig_Luftenglanz]

C# as a language is more flexible and we may say "better" than Java. But Java has a far better, bigger and open ecosystem and multiplatform support. With C# you are basically traped in a golden cage made and controlled by Microsoft, I know the latest versions of .NET framework (.Net core) has multiplatform support but it came very late AND the multiplatform support it's incomplete (no win forms for Linux for example) also the nature of .NET in the past and all the legacy applications have made that basically 95% of C# development is focused on windows. Nothing wrong with that, but if you are not interested in windows development (both server and desktop) real world C# development will mostly target Microsoft and azure and that's a limitation.

[@GavinLon]

Awesome! Thank you! It's great to get a fairly detailed comment from the Java perspective! :)

It isn't 100% fair to say that the difference between Java and c# is that you can Write frontend in c#. In java you can do it as well. If you want to make such notion then you'd Rather have to compare These technologies instead of saying that Java lacks it

Java was my 2nd first programming language. Used it quite a bit until I started to hate it, then I switched to JavaScript with mostly Angular. Later on, I picked up on how some startups are combining Angular and .NET to create performant solutions. So, I embarked on a journey to learn C# language basics early this year. One thing I'm certain of is I'm staying with C# and .NET. Definitely it's better than Java.

I wish that C# would include the ability to add properties to enums like Java, but that's pretty much where it ends for me. Perhaps my biggest turn off with Java is that Oracle is the language steward. I also VERY much prefer Visual Studio over IntelliJ and Eclipse AND not having to deal with pom files.

[@GavinLon]

Thanks for this interesting comment. Visual Studio definitely makes life a lot easier. I wonder if Microsoft will add properties to enums in a future version of .NET - might happen :)

Oracle may be a bad company in general. But we should not judge by that optic as far as Oracle being steward of Java is concerned. Oracle turns out way better steward of Java. Those who observe objectively do recognize Oracle being good steward.

Java is more careful about introducing new syntax than C#. C# may not be very attractive in the moment, but in the long run you get a more stable language in Java. A good example is Java victual threads, it was carefully designed to make sure that functions are colorless, where c# is still stuck with colored functions and await/async. The trouble with having new syntax catering every new fad is that when it goes out of fashion you are left with language bloat. C++. is another example of language bloat going badly .

[@GavinLon]

I like your point about syntax. It is far more important to learn programming principles and fundamentals - code sugar can be good but it should not be a priority, as you say to follow every fad that comes along :)

[@dotnetforever]

What is the new systax is really bad in c# added in the latest releases?

[@slr150]

​ @DmitryBaranovskiyMrBaranovskyi The trouble is not with "new syntax" , it is when "new syntax" eventually becomes old syntax and goes out of fashion. I already gave you an example with sync/wait (these color your functions). Java accomplished the same thing as async/await without introducing a single keyword or having a color limitations on function calls (Lookup project loop/virtual threads). Although I think Java is better than C# when it comes to unnecessary features, it still has some historical baggage. I would personally pick Go instead of Java/C# for new projects. Go has minimal syntax, had virtual (green) threads from the start, avoids multiple ways of doing the same thing, and is relatively fast compared to C#/Java.

[@paulpach]

I work in Java most days at work. It is an ok language. Libraries like spring boot help make it more palatable. Then I go home and work on my own projects in C#. So if I have the choice, I will choose C# for many of the reasons you listed.

A few additional interesting things about C#: * It has a "dymanic" type which is the same as in Python - a dynamic type! It's slow but you can do things like that: dynamic my_var = 10; my_var = "hello"; * Since .NET 8 you could compile application to a native binary! It will have a Garbage Collector with it but you would not need .NET installed on the system! And also it works faster and uses less memory!

Started with C++, then python and then Java. Left all of that behind once i started using typescript. Got a job in Vuejs saw i was dealing with many api fetches & changing the data for my use case once fetched, so i started learning back end. Tried typescript blah. Java was a mess for it. Golang was great but didn’t have enough stuff built in. Rust was fun but without a framework i couldn’t learn how to use lifetimes but polonius might fix that soon. Then i finally tried C# seriously with their ugly bracket placements 😂. I love it. Dotnet 8/C# 12 is like a typed typescript. It’s my favorite language. The brackets i use K&R code style meaning them brackets are with the signature on the same line 😜. I usually use a big O notation project to learn a language & hands down C# was flawless in creating such a project. inline object creation with new = { } is one of the many js/ts type coding i love C# for.

Yes, Java is still more widely used than C# in general, but that gap is getting narrower. Java is certainly a great technology but I prefer .NET and C#.

[@farrenh]

C# is wayyy better than Java in terms of language design. But also its runtime is better. Don't listen to people who've invested decades in Java when they tell you that performance and resource use are roughly similar and it depends on the application. It's just not true. .Net runtime is more performant and uses less resources. And it absolutely slaughters Java in high concurrency tasks (1 million+ equivalent concurrent tasks on the same hardware) The video mentions pointers in C#, but doesn't mention that apart from the performance gains from doing some C# algorithms with direct pointers and pointer arithmetic (in an unsafe {...} scope), you can use pointers in C# to run inline assembly by getting a delegate function pointer to the start of a byte array representing assembly code. Which means you can get the same or better performance than C/C++ code using assembly for specific functions. I mean aside from just interoperating with C libraries, which you can also do. But Java can do that too. Also not mentioned in the video (because its mainly about the languages not their runtimes), but the .net runtime does tail-call optimization of recursive functions, whereas the JVM does not. You can google what that means, but the Cliff's notes version is: If you write a recursive function where the self reference is the last statement in the function, like this int myFunc(int i) { //do stuff with i if (someExitCondition) { return i; } else { return myFunc(i); } } The .net runtime will optimize it so that there is only ever one instance of the function on the stack. That means it can continue recursing (calling itself) endlessly, without constantly consuming more memory. No matter how many recursions it will only consume the memory required for a single instance of the function. The JVM, in contrast, will create a new instance of the function on every call, while preserving every previous instance, meaning if it recurses for ever it will continuously consume more memory and you *will* eventually get a stack overflow. Also not mentioned: Java *still* doesn't have properties (looks and behaves like a public variable or constant from the outside, getter and setter methods hidden under the hood) or events (much easier than using callback interfaces in Java) as first class language constructs, unlike C#. And they only just introduced pattern matching in Java. C# has had it for something like 7 years. And like most equivalent features, the C# version is much less verbose.

[@GavinLon]

Wow - thanks for these additional points. I especially love your point about recursion! When I've got the time I'd love to do a much deeper dive into C# vs Java. The points you make here show just how much thought has gone into .NET and C# optimisations.

First of all using pointer to reach C/C++ performance it is a dream dude, because C/C++ are compiled language while C# not. What about Java, Java's key target is multicore processors via multi threading which is more faster then async await . C# really fast to fetch requests form database, handling file system by using acync await while Java more faster for large data processing by using multy threading.

@@aliksargsyan2782 You can do true multithreading in C# so that's not really a Java advantage. It's just that Java defaults to multithreading as the idiomatic way of doing concurrency while async is the default idiomatic way of doing it in C# - not the *only* way. That's what makes C# so great. Its *far* more flexible and supports more paradigms in the base language than Java. And I have seen many, many benchmarks comparing optimized concurrent code spawning the same number of concurrent processes written by people who are intimately familiar with both languages and its simply a fact that C# murders Java when you get to very high numbers of concurrent tasks on the same hardware. I mean like 1 million + concurrent tasks. At much lower numbers of concurrent tasks Java has an advantage, but it vanishes and reverses when you scale. My practical experience with both languages and their runtimes makes me certain that the runtime engine is vastly better optimized for scaling, tail recursion and many other aspects .Net than Java's runtime is. It makes me very sad every time I have to work on a bunch of interacting but seperate Java projects (Like clients, servers, apps and libs) because I know that no matter how powerful my dev hardware, the JRE is going to greedily try to grab as much of my machine's resources as possible and not release them until I unload everything. Android Java development using Android Studio is the absolute worst, because even on a new dev laptop with 32GB of RAM I know that opening three projects simultaneously (like an app and two SDK library projects that it uses) and doing a bunch of builds will end up consuming most of my RAM and the machine becoming slightly sluggish and less unresponsive, at which point I must close everything and re-open it before continuing. I feel like people who mainly only develop in Java just don't realize how crap the experience is compared to working with other better optimized stacks. Also using pointers and pointer arithmetic in unsafe blocks of C# code does make it possible to make certain algorithms faster in C#, in a way that is not possible in Java. Its irrelevant to this discussion whether C# is slower than C++ (which is not Java) because its a bytecode language that is executed by a runtime. What's relevant is that it has constructs like unsafe scopes and pointers that make it possible to optimize some algorithms, in a way that is not possible in Java. But since you raised that point - although IIRC this is considered a hack and not recommended - you can actually hack C#s unsafe scopes and pointers to run actual native machine code inline. I've seen tutorials on how to do it. Which I mentioned above. Finally, you can now compile C# to actual native code, like go, rust and C++, in a non hacky way.

the question is very simplistic. You don't consider the historic point of view... From that point of view it was java (sun microsystems) who develop all this new technologies, architecture etc...

It is not only the language itself but Java frameworks that were developed ahead of anybody else...

[@GavinLon]

I wouldn't say that Microsoft just copied Java. I believe Microsoft was certainly influenced by Java (especially by the Java Runtime Environment and Java Virtual Machine), but I think C# was developed with a view to combine the rapid application development capabilities of Visual Basic and the power and expressiveness of C++ (in fact Anders Hejlsberg even said as much).

Yup I think once a company is committed to a technology (like Java) - it often doesn't make sense to move to a more modern technology because of the cost involved. I think having Microsoft support is a huge reason to develop green field applications using .NET and C#. Python is a great language but C# is better in my opinion, one of the main reasons being that C# is a statically typed language. I also think C# is a fairly easy language to learn.

[@astrahcat1212]

@@GavinLonI'm actually more of a C# programmer myself, but learning Python I do enjoy the quick compilation with it being interpreter based. The younger generation all seem to be learning Python though, and CS students and many companies, so I think it'll continue to expand and grow. C#'s syntax still makes perfect sense to me though.

[@GavinLon]

@@astrahcat1212 Python is a great language, and of course great for AI and data science applications. I prefer C# for many reasons but think Python is a great first language to learn primarily because of its simplicity. :)

C# and its ecosystem is (nowadays) developed by more smarter people than those in Oracle struggling to develop java. That's the main, perhaps only reason why c# is really more productive in action.

[@GavinLon]

As you have alluded to in your comment, Microsoft is certainly in a position where they can hire the best people :) That of course is reflected in the quality of their products.

[@kaihusravnajmiddinov5413]

@@GavinLon yes, agree. But again, I am not sure if any tech company which got similar financial capability may reach the same results. E.g. apple is very rich company, but it's programming languages (objective c, swift) are far from being good problem solver, rather than on it's own hardware.

@kaihusravnajmiddinov5413 Interesting point, I do think for e.g. Anders Hejlsberg (who lead the team that designed and developed C#) is exceptional.

[@benderbg]

C# and Java can be called OOP language siblings. After all C# was developed as a Java clone. Why not learn both and be a true back end guru! Now days, C# has a nicer syntax and feels more modern. Java on the other hand has bigger ecosystem not tide to only one company. There is a reason why big tech don't prefer C# because everything around it is opinionated. If you want maximum out of it you need to be in Windows/Azure world. I'd also like for Microsoft to port Visual Studio to Linux. Its not really cross platform language until it has full IDE support it deserves. MAUI is also not supported on Linux at all.

[@GavinLon]

Very interesting comment! I really enjoyed reading it! With every release of .NET there seems to be amazing progress, so I think with the heavy investment in C# and .NET by Microsoft - we'll see a lot of positive changes - perhaps that will address the issues that you have mentioned in your comment. Having said that , I do like a lot of the points you make here :)

C# copied Java since it born

[@GavinLon]

C# is certainly not a Java clone and is much closer to C++ in its design. It of course does have a lot in common with Java. One has to bear in mind that both of these languages are both C based and support object oriented programming. Anders Hejlsberg (the designer of C# at Microsoft) said the goal (when creating C#) was to provide the power and expressiveness of C++ as well as the rapid application capabilities of Visual Basic. Certainly the JVM and the CLR are very similar when comparing .NET to the JRE - the C# language itself, however, has evolved and seems likely to continue to evolve far beyond Java.

[@eriknyk2k]

@@GavinLon It isn’t anymore, but here’s a brief history: In the late 1990s, Sun Microsystems developed a language they called Java. At the time, most programs were written for a specific operating system. Some languages were “portable”, but the source code had to be recompiled for every new system. Java allowed a program to be written once, compiled and then run on any operating system. Nifty! In addition, small programs could be run inside a web page. Microsoft got on board and started supporting Java: they supported it in their browser and even released a version of their IDE for it. While doing this work, they came up with ways of improving Java just for Windows. This pissed off Sun, because that was the opposite of what Java was all about: the same program was supposed to run the same on all devices. It wasn’t supposed to be different for different operating systems. Microsoft got mad that Sun was being mean to them, and withdrew native support for Java in their browsers and killed their Java IDE. They decided to make their own competing language, which brought us C#. In the beginning, C# was similar to Java in many respects. Java compiled to “byte code”, which was then executed by something called the Java Virtual Machine (JVM). C# compiled to Microsoft Intermediate Language (MSIL), which was the same idea as byte code. It was then executed by the .NET Framework, which was an idea similar to the JVM. C# borrowed a number of ideas from Java, such as the lack of raw pointers, using . for dereferencing always instead of . sometimes and -> at other times, a construct that C++ used. But right from the start, there were differences. Anders Hejlsberg, the lead designer of C#, added something called properties, which were a big boon to C# programming, and still are. They also included enums, which Java lacked (Java has them now, but considers them full classes or some such weirdness). Now, almost 20 years later, C# has a number of features that Java can’t touch. I won’t cover them here, but C# is less of an imitation of Java now than it originally was. C# and Java continue to borrow from each other as each continues to try to one-up each other. They still share a number of similarities. Most C# programmers would have little trouble reading Java and vice-versa (though a Java programmer’s head might explode trying to read some LINQ statements). C# started out as an imitation of Java (or a competitor), but now stands on its own.

Kotlin

[@GavinLon]

Okay challenge accepted - coming soon - Is C# better that Kotlin?

[@RuanStrydom]

No challenge. Kotlin is a much safer language. It prefers immutability over mutability. Coroutines enforces structured concurrency and is generally just better designed. Sequences vs the random implementations of Ienumerable. The list goes on and on. .Net == infinite runtime errors. Oh and not to mention kotlin multiplatform and all it's targets, JS, wasm, native, JVM.

[@GavinLon]

@@RuanStrydom Thanks for your strong views - well I look forward to diving into this comparison further. I disagree about .NET = infinite runtime errors. In my experience .NET is very robust.

[@RuanStrydom]

@@GavinLon I would argue Rust is robust. Type safe functional languages are robust. A mutable language with unbound concurrency I would not describe robust. I'm looking forward to the video, I hope you spend some time with it, it's a good language. Not great but good. PS I'm currently in a C# job.

[@lufenmartofilia5804]

They kinda copy each other over the years. Java take c# as a testing ground and only take features that they think make sense. C# is looking into copying java's virtual threads at the moment as it is a clean and very lightweight way to transform blocking code to none blocking one on a giant scale (1kb per vthreads vs 1mb for a thread). Allowing you to pop millions of them without running out of ram

[@eugenschabenberger5772]

[@farrenh]

C# is hands-down better for game dev. 2 of the 3 most used game engines (Godot and Unity) support C#, with good reason. Java isn't even on the map in serious game development, although if you're developing games that don't require optimal performance, you can certainly use Java if you want to.
