New Java Version 22 - The 3 Best New Features You'll ACTUALLY Use

[@MelHaynesJr]

Java is older than many people using it, and it's amazing we are just now getting this String feature.

[@adiveler]

Yeah! C#, Python, and JS had this for ages!

[@JorgetePanete]

Not yet, they'll be iterating on it and is now removed.

[@boss50726]

I think java is now realizing that it will loose it's charm for new gen

[@allwoundup3574]

Because java is trash and was developed by a kiddie diddler

[@noJobProgrammer]

@@adiveler C# is just a copy of Java, there is nothing special in it

[@terrificfrogg8377]

The string template is amazing but having to begin with STR to make it work is just so Java

[@CodingWithJohn]

I think it's technically needed for backward compatibility, since without it if some string literal happens to contain \{something}, it would break when they upgrade the Java version.

[@PimPumSObaka]

+++ This whole feature literally screams JAVA lol

[@sstrenn]

Do you know why they couldn’t just put an f in front of the string, like python, to indicate a formatted string to the compiler?

[@DinMamma002]

@@CodingWithJohn How is it needed for backward compatibility? "\{" is not allowed by the compiler afaik.

[@havlli7544]

@@CodingWithJohn It is a design decision as well, from what I could understand from their latest talks about these new features the reason is to give developers the ability to create their custom template processors that can have additional logic, they gave the example of creating a custom SQL template processor that would have sanitizing included in the template processor logic itself so you could just call SQL."query with parameters" in the database layer and not to worry about sanitizing because that will be centralized in the template processor itself. You could use it to adhere to formatting standards for the queries and greatly reduce boilerplate code. There are more use cases for sure but I cant come up with any from the top of my head :D

[@TheMoviemaker98]

Thanks for the tip! Told grandma about Java's new unnamed variables feature and she's finally considering upgrading from Java 8, her exact words were "About damn time."

[@more_than_just_sentient]

[@asitabhpaul]

An underscore in Java is elevated but not sports 😅

[@Kiyuja]

String templates sounds good but it needs a little work I feel. This is the same concept as string interpolation in C# and its a little more friendly, you just add a $ in front of a string and then use the same braces as with the preview here like: $"part1 {insert} part2". Its quick and easy to use. The "_" is also a thing called disposables I believe and it can be really useful. I am happy to see Java catching up a little and hopefully they work on asynchronous execution in the future.

[@nakarukatoshi]

The thing is that they decide to go with processors because programmers can create their custom ones, like custom HTML, YAML, JSON, SQL, ... processors that will sanitaze the variables I think some frameworks like Hibernate will implement different SQL sanitizer processors, and Jackson will do JSON and YAML processors for example

[@mukynas]

Don't we already have string format? You just have to add all the variables in the correct order at the end. My first language was Python and string templates looks very good and comfortable

[@Kiyuja]

@@mukynas yes, Java does provide formatting for Strings. However this is about concatenation. Oftentimes in programming you just quickly wanna combine information, like in error messages. This should be as friendly and quick as possible. String Interpolation lets you do just that. Imagine you have a variable x. In C# you can write $"error occured while parsing {x}". Because you marked the string with a "$" C# knows curly braces will reference data and not be characters and inserts the value in the string. Javas proposal aims for the same functionality but it seems quiet cumbersome...

[@thebuizelclub]

Why not just do both then. $ for the default and STL for custom implementation .@@nakarukatoshi

[@gamingzonezone1]

Hi bro can we be friends

[@LittleEngineCan]

Great to see you back! Like the new format and humor. Any updates planned for your bootcamp course? Would be great to see new modules added, or even a new advanced ‘part 2’ course

[@dirkniblickable]

In lieu of chapter markers: * 1:43 - Unnamed variables * 7:03 - Compile and execute multi-file Java programs from command line * 9:14 - String templating (preview only)

[@paulthomas1052]

Thanks for the great intro to Java 22. Look forward to more !

[@Mig440]

Unfortunately, the string templates feature has been removed for now from std. Lib since they want iterate on the design at bit further before releasing it to the public. Just good to be aware of.

[@terrycrews1584]

Dang, thought we will finally get rid of that pain in the ass of concatenation! 😂

[@davidc_ac9377]

It has always been experimental in v21 and v22. It was not removed, because it was never standard.

[@Mig440]

@@davidc_ac9377 true, but people might still think they can experiment with it on their own in jdk 23 and that will currently be impossible 😊

[@MrXperx]

I came from a JS background to a Java project and the lack of string templating drove me nuts. I started to use String.format which isn't that bad.

[@YouHaveTrouble]

in java 17 and up you can do "Some random string with %s format".formatted("special"); which is more convenient imo

[@MrXperx]

@@YouHaveTrouble thanks. I'll try it.

[@tylerzhang601]

LOVE YOU! YOUR VIDEOS ARE ACTUALLY SO HELPFUL

[@withgrowinginsanity198]

11:49 what about the existing feature "my name is %s".formatted(name); no STR and very confusing looking (especially inside HTML) "\" needed ...

[@GrantSR]

So, if you are going to start with the advertisement, right at the beginning, I got a question for you: Do I have to pay for each those customized IDEs separately? Or do I just buy one IDE and then just switch modes, preferably with downloadable modules like with Eclipse?

[@simulbista8846]

Great to have you back.

[@dembro27]

They implemented my unreasonably favorite JavaScript feature, template literals, into Java. Finally!!! String.format is pretty good, though.

[@Sunnnix]

For the third feature, I always used String.format because it's easier to read

[@dirkniblickable]

“%s is even easier”.formatted(“This”);

[@alexandersagen3753]

Or just "my name is %s".formatted(myName)

[@nambipugal3329]

Hi John, Eagerly waiting for more videos especially on Spring Security 🙃

[@imohanthony]

This video presentation was so cool am considering picking up java again.

[@antonyrichard369]

Not to compare as I love Java too .. but the string template feature is something .Net has implemented a few years back and Unix operating system has it way way long back .. I feel like Java is more moving towards like a scripting language like python or Java script and more of functional programming ofcourse

[@alokik4923]

The current problem is it is always moving, I think it just shifting here and there to survive in the world of language wars. Java has been shifting it's programming style a lot lately. Which is not good

[@lakrinmex8132]

I didn't know about triple quote making it multiline string. I just tried and it worked in the java version I currently use. Unrealted: Why doesn't my intellij(community edition) suggest whole lines like yours does? like when you typed Cat myCat it showed "= new MyCat(); tab to continue"

[@PimPumSObaka]

Those features are amazing, but... the '_' underscore variable discarding was in C# since 7.0 and they should definitely add more like from there :) The syntax sugar in C# makes it much much much better to use, so when java introduces something like this it interests me again in making things in Java

[@sqlexp]

He missed the points of it, though. First, it is used to silence any "unused variable" warning (if Java has such a thing). Second, it saves the programmer from the need to come up with different distinct names for multiple unreferenced variables in the same scope.

[@girishvm2335]

But for the exception object we may use it For ex (Exception e) { logger.erro(e.getMessage) } But if you refer unnamed variable how do you get message or stack trace out of it? Can you suggest ?

[@josueramirez7247]

In that case, then you shouldn’t use the underscore (blank) name for your variable.

[@NBSgamesAT]

String templating is a thing from other languges and it works qithout having to add that str thing. But it‘s still soo good that after such a long time, Java can actually use a feature from other languages that is actually super helpful, makes me have a lot less issues with Java again.

[@CGDW2]

Unnamed variables I will use occasionally, but String templates are really nice. I do sometimes use String.format() or printf() rather than concatenation, but they still feel kinda clunky in their syntax.

[@CodingWithJohn]

Looks like it's unfortunately being removed even as a preview feature in Java 23, but hopefully to return in an even better format in a future release.

[@xtunasil0]

Java is finally catching up on basics features it was missing. About time!

[@loic.bertrand]

String Templates (which was a preview feature) have been removed in JDK 23. They got feedback and saw that it wasn't really great to work with. There will probably be a new proposal without "String Template Processors", because we can simply use methods to process a String Template and it's more composable this way.

[@zfazzershroudvietcynide64e58]

Please pleaseeee make a video about Comparable and Comparator coz i really like how simple and easy ur explanation is

[@Morzelius]

I'm pretty sure they wanted to find the most uncomfortable syntax possible to do string templating. Maybe they checked how the popular languages doing that and wanted to create something that worse.

[@manoelcamposdev]

If it wasn’t due to the possibility to create any custom string processor you want, I would agree. But Oracle looked at other languages and included an awesome feature. For instance, you can create a JSON string processor or a SQL processor that avoids SQL injection. It’s just amazing and sometimes a simple lambda.

[@NadChel1]

String templating is awesome. I was hoping for something like this for a long time. Though I wonder why they didn't go with backticks like JS with its string interpolation. STR is less appealing to my eye

[@adamrigely3607]

Hey John, another great video, thank you! I was wondering if you know something about Java Serialization? It is a topic I would love to see in a video, because it is very useful, but it feels like magic to me. I would love to see a good explanation of it so I know how to use it properly!

[@alexandersagen3753]

Just a heads up, most do not recommend java serialization (Serializable and so on) as it has had so many extremely bad security vulnerabilities forever. The recommended solution is to serialize the objects to json or whatever format you prefer and use that. Many great extremely fast libraries for most if not all formats you could think of

[@anne_the_dev]

Hi John, I'm Anne and I have been programming for almost 5 months and I'm about to learn data structures, but I'm considering switching to js since it's really hard to do so in Java + I already know HTML and CSS so is it worth the switch? And I also get a bit overwhelmed after people talking about complex stuff, so any suggestion to avoiding that? BTW thanks for the generics tutorial it was awesome ❤ Btw I use vs code so sorry, I can't switch to jet brains.... Yet

[@CodingWithJohn]

Ha no worries! Well I don't know if javascript is heavily used for data structures work, particularly with HTML/CSS. Together those are mostly for the front ends of websites, and not so much for data structure work behind the scenes. Between those I would stay with Java, although there are definitely other options too. The tough part will be the concepts of data structures, and probably not so much the actual language you use to implement them. Just get started with the simplest stuff you can understand, and work from there. Try to go step by step, implementing something very simple and let it sink in, code it yourself and mess around with it, doing a lot of testing. Then take small steps forward, making it more complex as you get more familiar. If you have specific topics that others might be interested in as well, let me know and you might see a video about it!

[@anne_the_dev]

@@CodingWithJohn thanks you so much!!! Yeah I have a video idea: maven tutorial

[@aravindmuthu5748]

if you know HTML and CSS, the next logical step is to learn JS without which web development is incomplete tbh. It is better to pause your Java for now, because it could get quite confusing from J to JS. Both are drastically different languages (why did they name it JAVAscript tho???) and once you try js, all the object oriented programming gets thrown out of the window, and you'll be needing to learn functional programming, which btw is waayyyyy easier than OOP approach. Once you feel like you're comfortable with it, you can decide whether to switch back, because honestly Java is mainly used in big enterprise companies and JS is used by lean and fast teams. So in conclusion, you either leave out web development and concentrate on Java, it has got its long term benefits or abandon Java(for now) and concentrate on JS which will speed up your programming skills itself and you can land a job quicker...

[@ZachariBarnes]

You can do data structure work in JavaScript but JavaScript doesn't have many built in data types for handling those sorts of objects and often you'll need to pull in a npm package or write your own, which will add a lot of complexity to your programs. Stick with Java or another back-end language more suited to data structure manipulation

[@jaybee2530]

A good possible alternative for Java would be C#. My first language was Java, and it can be a bit daunting to learn at first, but i'm very happy i stuck with it. It gives me a greater understanding of programming concepts than if i would have started to learn with Python for instance. Either way, whatever language you pick, learn the language thourough. Don't hop from one language to the other only learning a bit about each language, and don't worry about getting overwhelmed either. Programming can be difficult. So, take a breath, make a coffee, and take it one step at a time. Good luck!

Later i wanted to make the StringBuilder outside the loop. But i was appending something in the string builder inside the loop. After appending and generating string i had to clean up the string builder for next iteration. I could not clean the string builder. I tried setLength(0), delete method. But the bytes inside value array still exists.

[@jelmerterburg3588]

What is the issue, exactly? The values of the internal char array of the StringBuilder do not matter, setLength(0) is sufficient to reset it. StringBuilder does not perform any unnecessary operations on the internal buffer.
