As a developer who has a lot of experience in both of these languages, I believe you did a very good job in comparing the two. That said, I strongly believe if you CAN do what you want in C#, there's almost no argument that persuades you to use Java. Basically, if you have to use Java to use a certain library, by all means, do it. But if I had to choose either of these languages I would NEVER choose Java. There are so many things wrong with it (Unicode?)

C# has less boilerplate, fantastic syntactical sugar features which make coding a breeze (Once you know them), extension methods are really awesome for configuring services for application startup (IServiceCollection). The new MinimalApi makes writing API endpoints super simple and fast for simple dev testing etc. All in all, it feels like a more modern language which has matured well, unlike Java. Sorry if I ruffled some feathers but it's just my opinion. :)

Try Groovy as a "Better Java" sometime.

[@pauldanielmooney]

Syntactically Java is very out of date, and in my mind it always will be until it can do simple things like auto properties (adding a library like Lombok that requires IDE plugins and build alterations doesn’t count), and more advanced things like Async Await. I believe it’s advantage is that is has a good trusted ecosystem in spring, Apache commons, and a few others. I want to say Kotlin is the answer here but even that language seems to stumble in a lot of places. At least that’s how it seems with my current understanding of it.

Amazing comparison! My main language is C# and I recently learned Java and... I don't hate Java per say, but it just seems inferior to C# in every way, especially since C# is now multiplatform (though I've only ever used Windows anyway). My typical workflow relies heavily on things like properties, events, nullables, and LINQ, so whenever I use Java I'm constantly bumping into inconvenience after inconvenience. Even if they're minor, they add up to frustrate me quite a bit, so this video kind of validates those feelings lol.

[@ozgurugur5196]

Thank God for the competition created by Java. Otherwise, there would not be such a shining and powerfull language called c#. For more than 20 years I have been coming across such comparisons. In the beginning, it was "c vs java". C# takes features from java (vm, open-source philosophy), java takes features from kotlin (records) , c# (lambdas, virtual-threads), javascript (promises, declarative programming, reactive)(and golang latest version supports generics at last). The thing you have chosen is not only the language itself, it 's also the open-source community behind the scenes. Long live open-source, even the companies have been funding foundations to drive the open-source community.

Kotlin/Swift/Typescript front ends with a C# backend, and I have to say, languages are in a good place at the moment. All of the native front ends do a great job of not getting in the way while providing great developer experiences. C# and .NET are great as well, with batteries included. If I had to use the JVM, I would go with Kotlin over Java.

[@alexclark6777]

Microsoft sacrificed backwards compatibility by implementing generics from the ground up the right way. Java maintained backward compatibility by utilizing type erasure. However, there are more implications than just Reflection. The vast majority of generic programming surrounds the collection types, which use an array as their backing store, and the difference is particularly evident for primitive value types. If you wanted a Java List and the bools have to be converted to objects (boxed), they're taking significantly more space on the heap and getting scattered (your array now holds references to other heap locations). A .NET List uses an actual concrete array of bool behind the scenes, should hold the data in a contiguous block of memory, and doesn't suffer from the same inefficiencies.

[@victorbukowsky7496]

lol this is some thick material. Awesome comparison. I work in both, and I greatly greatly prefer C# and .NET. I could go on for hours why - it's just everything is already packaged for you, from a single source really - Microsoft. In Java, you, the programmer, has to sit there and configure third-party tools - it's a major nightmare! Version matching is horrendous. Yes, there is Maven, etc. But it's another thing you have to waste time and effort on, just to make it work! And any issues with that - you are on your own, good luck lol!

[@RustedCroaker]

"a single source really - Microsoft" That exactly what kills C# for me. Being dependent on a single source is never a good idea. Especially if that source is Microsoft.

[@TheBoxyBear]

Small clarification: Both Java and C# offer features through classes, but C# simply offers syntax aliases for these classes, which are sometimes structs. Like with the nullable example, the question mark is removed in CL and becomes a reference to the generic Nullable struct. You may use the struct like any other and the values are interchangable with variables defined using the nullable syntax, but IDEs may detect the use of the struct and suggest the designated syntax. This also extends to LINQ for which the query syntax shown is an alias for a chain of LINQ extension method calls. This doesn't mean the lack of extension methods is preventing Java from having something comparabie to LINQ. In reality, you could always use method calls inside method calls just like you can in C# through the static Enumerable class. The reason LINQ is based on extension methods in the first place was to simplify the syntax when calling the methods. The query syntax was only added later to further, making it ressemble SQL. As for checked exceptions, although there is no way to signal potential exceptions that will have an impact on the assembly, C# does support signaling of potential exceptions through XML documentation that references the assembly. This allows for an IDE to read the documentation file and show context-sensitive documentation including possible exception at the programmer's request.

Newer languages stand on the shoulders of the great languages that preceded them. Java is great and we would not be here in software programming without Java. There would definitely be no C#. Microsoft took a lot of ideas from Java and added their own stuff to make it better and that's how C# was born. Initially, the languages were very similar but they are quite different now because of the effort put into developing it by Microsoft. It doesn't feel like there was enough effort and innovation put into the language after Java gained popularity. For this reason, Java feels quite outdated to me despite being a great language.

The only feature that Oracle cares about is backwards compatibility. The newest JVM will still run java applications from a lifetime ago. (Sometimes re-configuration is required.)

Generic classes being generated for each generic type doesn't just matter for reflection. It also matters for performance and static fields. Java uses type erasure, which means generics are fake.

While Java is dominated by Indian guys, and so you won't find any good forums in english, at all lol Everything is 3rd party in Java - literally NO documentation, of any sort lolol Maybe some support on the CURRENT versions only, but anything 1-2 years older+, you are totally on your own. Go with C#, if you are in doubt. Javascript by the way, might give you incorrect perception of real programming - JS is not really a full language. So I would advise to quickly move into a good enterprise language, or you might get wrong ideas. Cheers, GL

@@victorbukowsky7496 I really appreciate the wisdom. Also, documentation is very important I noticed, perfect example React has really good documentation. Originally I was thinking about Vue but a lot of the documentation is decent. I felt React had better documentation which is why I decided to use this library. Also, I see where your going with learning JavaScript, its a complicated language. Class system is prototypical? it isn't like Java or C#, a class is a class. At the moment I had learned the fundamentals and I am learning to work with the DOM now. Once I have a handle on the DOM, CSS- flex-box, and high array functions. I will move onto React. After I have a good handle on React. Finally I will choose C#. Just want to make sure I know the tool kit well before adopting another tool set. But I appreciate your invaluable insight it is much appreciated. I am strongly considering C#. I will revue the documentation for C#, thank you once again.

[@victorbukowsky7496]

@@DevlogBill yes, classes in Javascript are just syntactic sugar - meaning they just look like classes, but aren't'. For many reason, because there is no even compilation in Javascript anyway, it's all just interpreted runtime. DOM is great - this your foundation, for entire front end. What DOM really is just the browser object, that you are allowed to work with, using Javascript. But DOM is just an object, written in C++ or Swift for Apple or whatever a particular browser is written in. React - I would advise to wait with it. I know it, it's pretty confusing. If you want to learn front end framework - go with Angular, you won't miss out on that. Much better choice than React. Yes, React is hot, but it's weird, and has very limited niche - it's for highly reactive quick websites. You shouldn't clog your mind with that stuff right now. My advise - finish up with Javascript, maybe go into Angular, and then quickly move into C#. This is where the real programming is, and REAL MONEY is. Job market for C# is very hot, specially in the USA, Canada, etc. I don't know where you are. Skip Vue as well, don't waste time on it. It's junk anyway, I kinda know it - just skip it. Good luck, friend! lol you have a quite a road ahead of you, but it's massively fun. I enjoyed my trip. And money is ridiculous lol Plus freelancing/consulting possibility down the road.

[@DevlogBill]

@@victorbukowsky7496 I really appreciate your insight, you give a different perspective on things. What I think is confusing with React is JSX. It looks like JavaScript with HTML plugged into the code break. I hear from some developers that you could learn JSX and React first then jump into the fundamentals. But me personally? I figured it would be much smarter to get a strong grasp on the fundamentals since these libraries and frameworks are constructed for JavaScript. I will begin a framework around mid-May. What is the best approach to learn Angular? I believe the best approach is to take the entire framework Angular and learn the syntax first. Next learn about the modules and components next. What was your approach with learning Angular? Today I will download the documentation and visit the website to gain a better understanding of Angular. Also, I live in NYC so there is a strong market for C#, JavaScript, Java, etc. etc. When I check indeed I see jobs for C# but I keep on running into so many jobs for Java. But I noticed something. Most of those jobs from what it looks like I am not sure but it seems they are looking for people to update their back-end or maintain it. I don't see anything mentioned about creating new products using Java. Also, I downloaded some plugins for C# into my visual studio code, soon I will look into what is C#.

If a developer asked me which the learn, one of my first questions would be what kinds of companies do you want to work for? If you want to work on line of business apps in established companies, C#. If you want to work in west coast startups or big tech, Java. I definitely like the C# language and tool stack better, but because C# started out life as Windows-dependent, Java ended up dominant in cultures that didn’t want to depend on Windows. Thankfully the dependency went away, but the inertia from that history remains

[@DevlogBill]

I know this is probably a horrible analogy, but it almost feels like when you compare C# and Java. It sounds like the same arguments the C and C++ camps debate over. But to be honest? If I had to choose, I think I would go with C# and .NET for the simple fact everything you need is all together under the .NET framework. Java feels all over the place. Don't get me wrong? I like Java as well; they feel like the same language even though they aren't. Basically, finding learning material for C# seems to be so far easier to find in comparison to Java. For example, for Java to set up my environment was such a difficult task. I had to download from Oracle I think they call it an SDK. Next, I forgot what they call it I had to download some file. finally, I downloaded IntelliJ which is a cool IDE and finally when I tried to run Java on VSCode, my code wouldn't run. I found the C# ecosystem a little bit easier to find material to learn from. Also, there are different versions of Java which isn't recommended to use? I found this confusing. For example, what is Java FX? With C# I downloaded Visual Studio and I quickly found lots of material for how to get started and had an easier time figuring things out. At the moment I stopped this, and I am purely focused on JavaScript. But after I learned React, I will pick up most likely Java because of the huge job market. I am in NYC, and I can tell you that from indeed.com there were only 237 jobs post for C# and .NET and over 1,227 jobs post for Java. Despite what my personal feelings are if you want to find your first job you have to go where everyone fishing to catch fish. Sorry for the horrible analogies but I hope you get the point. This is from a newbie's perspective I am not a professional. This was my struggle as a newbie so far. Also, I would like to thank everyone for providing me with such insightful advice throughout my learning path. It has given me much needed guidance throughout these past couple of months.

C# allows C++ inside the code (with the proper compiler settings). I prefer C# over Java, and recently played around with Kotlin for the first time (Android relies on it heavily). They both work, but I found C# just prettier, feels better, makes more sense to me. Java feels like it's somewhere between C++ and C# and with all the 3rd party libraries, I often find myself lost in the maze of different (and often terrible) naming conventions and bad documentation. Kotlin doesn't have that problem (as much), but that's probably for the same reason C# doesn't have that problem (as much); A big and solid enough foundation, support and use by others for the time and effort put into making great documentation. I'm not against Java by any means, but it just doesn't work for me 😅

[@jongeduard]

WHAT?? C++ inside the code? Who ever made you believe that? You probably just mean unsafe programming with pointers, however that's still far from C and C++. And it's not even a real subset of these languages, since there are multiple fundamental differences as well.

The funny thing is all that semantic abstraction turns out to be just bytes that were put in memory in a logical arrangement wich are sequentially read by the CPU wich reacts to them in a certain manner depending on their values and, in turn, outputs signals in certain ways as to control devices such as video cards, sound cards etc. so that we can see or hear the result of all that and use it to our advantage.

Hi McCullough, I know Java and C# are both OOP languages but the language I am learning at the moment JavaScript isn't? JavaScript is prototypically written. I find this very confusing. What exactly is prototypical? Would this hinder my learning or understanding of what real OOP is in comparison to Java or C#? Which is real OOP? I am at the stage where I understand the fundamentals and I am trying to learn more advance topics with JavaScript like recursive functions and gain a better understanding of pure functions versus class-based functions. Eventually I will migrate to either Java or C# for a back-end language. I am trying to learn JavaScript on a deep level so that I am able to better understand other languages with better ease when I move onto the next one. Or would it be best if I gained a deeper knowledge of languages like C# and Java versus learning from a prototypical language like JavaScript since Java and C# are true OOP languages? What would be your recommendations? Thanks McCullough most appreciative.

[@McCulloughAssociates]

Great question. But the answer is a little tough to elaborate in a comment! For basic stuff like loops, conditionals and functions, conceptually similar. I think strongly typed vs untyped JavaScript is as big a hump as perhaps the object oriented features. Remember, ultimately everything executes machine code using memory, cpu, and IO. I have several videos on SOLID design- take a look. They might shine some light on OOP concepts

[@bariole]

Sun's Java, like the referent one, has been running generational GC since late nineties. Technically speaking, GC is not mandatory part of JVM, and varius JVM implementations have completly different GC algorithms at any point of time. Being "generational" is also not a significat benefit or a failure, as implementation details are far more important than "generational", "copy", "segmented", "precise", "stop-the-world", "realtime" or whatever else comes.. Also for running server code, the most important aspect of GC, is ability of allocator to reuse unused "holes" within memoryspace as not using those leads to memory leak because of fragmentation. A classic C problem. The remedy for that is usually "copy collector", or in modern times, segmented one. Many "generational" GC algorithms are often also "copy collectors", but they don't have to be.

[@iXPilot]

I have a feeling, that Chuck maybe was confused by G1GC because it is complicated and it was in development for a very long time, or maybe by J2ME due to it's difference in memory management or maybe by difference between "server" and "desktop" versions of JIT compilers (I actually don't know where else that "desktop" idea could came from)... But anyway, this part of the video could be better: I work with Java and I see evolution of the GCs: first it was CMS, then G1GC and now Shenandoah so I'm curious how it's going in the .Net world, especially after seeing the failure of Go's GCs, but eh...

[@CouchPotatoWizard]

I wouldn't mind a deep explanation of checked exceptions and why they are an anti pattern.

[@McCulloughAssociates]

Think of it this way - exceptions (c++) replaced return codes. Return codes required each function on the call stack between the error and the handler to recognize and propagate the error. Lots of points of failure. Exceptions allow the thrower and the catcher to be the only code to be exception aware - everything else is exception illiterate. Forcing each method to declare a throw puts us back into the return code paradigm. In practice, error conditions are usually considered in later iterations. An error detection would occur in lower level code whilst handling in application layer code. One would have to modify all of the code inbetween with the throw declarations. Take HttpServlet as an example. The doXxx methods all throw Servlet and IO exceptions. A subclass probably invokes other methods that might throw SQL exceptions. The override can only throw the declared exceptions. Many developers make the mistake of catching and dumping the SQL exception. The right answer is to catch and rethrow one of the declared exceptions or runtime exception. This is just more code where mistakes can be made. If the exception were just a runtime (unchecked) to start with, maintenance would be much easier because the middle code wouldn't have to deal with it. This is why the DispatcherServlet in Spring catches checked exceptions and rethrows runtime exceptions - so that the application code doesn't have to get boxed into throw decls. Stroustrup cites a similar scenario to justify the change in C++ 11 to have the compiler ignore exception declarations. It looked good on paper, but in reality, exception declarations on function signatures caused more harm than good.

Great video, but there is one thing missing here - comparing the project structure. In modern C# you have 5 lines in a csproj for, and you already are able to build, run and debug the program both by running "dotnet build" command, and in Visual studio. For Java, at least in templates, it's by far way more complicated. First of of all, you need to know me syntax, groovy (while everyone knows basic XML). Secondly, you cannot use javac, if you want to have any maven dependency, you need Gradle to compile. Please, correct me if I'm wrong, but I tried to replicate few programs in Java to compare them myself and got stuck at the setup part - I just wanted single Java file with ability to add dependencies and to be able to F5 debug in InteliJ.
