Sir I have one question..?
In jdk 21, we really able to use void main() without using class name in big coding also ..?
I have also same doubt on this new update@@arpitha.b_0128
It's easy for Trainers now to explain first java program....😅
It would be more than awesome with the new update as for beginners. But personally, and I just started Java 3 4 months ago, the old style to start a project has been in my head. So it's great that the Java devs actually keep it like a signature for this language.
Sir I have learned so many things from you ❤️.Sir please focus on creating some basic projects which involves Oop concept... Love from Pakistan 🇵🇰🇮🇳❤️
Watch sir complete Java programming in 7 hours you will get oops and so many
Why no top level functions.. is there some restrictions in JVM? Because Kotlin allows you to write clean top level functions without classes but when they go to JVM they need to wrap them with some class names, don't they?
bring any update for main thread , but please dont deprecate the vintage ..... (because.. now we cant clear console output using java. we could clear only with clicking the clear console button)
your spring boot tutorial help me sir very ,it is old but best relevent...thank you sir.🤩
Same I need that link
Hello Navin sir Firstly I would like to share my experience with java when I was first learning java when I saw this line public static void main ( string args[]) my mind just got boggled because why I actually need to write this big line when I have started learning C it is such a simple language with simple syntax when I came to java the one thing really got irritated is to remember that big line perfectly everytime when we write our java code really used to raise a question in my mind that why would I really need to write this whole thing I knew that it's a object oriented language and they deeply wanted show it is so clearly purely object oriented programming with those classes and all but why is that so necessary why can't make it simple read write and learn like we see in C C++ it's so simplified code the code looks so simple the thing C C++ can't be used for apps or many others purposes it only used on System software that's the major drawback but if C C++ has the potential to replace java then I would have never touched again java in my life because of that long syntax and long statements that verbose in nature makes me so difficult to understand we are in a era of advancement of languages writing shorter code simplified code we don't everything we just need a simple code that easily written and executed in a shorter having longer code is a big drawback of java like it has system.out.println omg this big line to just print a small string of Hello world and everytime whenever we need to print something we always need to use this as we now a days even the first high level C has just printf even C++ has Cout and python has print it's so concerning everytime to write this system.out.println why actually needed to write they say it's a class but it's ok to make it simple to write whenever the println or print statement is written the compiler should automatically invoke the system.out class internally with making a problem to mention it every single time it's a minimum common sense those early developers of java should have they didn't thought about the problems facing this long code for scanner it requires two lines of code and still I can't remember the scanner and sometimes I get confused with those two lines what to mention you always have create object for scanner class and then a variable why is it even required to follow this whole process why can't make it so simple to just write a variable and it's automatically gets declared to the particular data type there's no need to show off writing scanner is a class it has a object then a variable isn't it looks so difficult to learn for beginner like me always crushing my feelings whenever I tried to learn Java I always got so demotivated to learn this language and then only compulsion is that many companies use java no doubt java has many good features and many outstanding uses but what is the use when it is so hard to remember and write every time it doesn't look like a great code always writing those big lines of code it's very difficult for me understand why the developers of java didn't worked on these issues at some point my intention is only to have a replica of simplified java language with simplified syntax yes we know java has so much internally just atleast those basic things are very difficult to write as you said in this video it's very difficult for myself to convince myself that java easy language once start learning because from the beginning itself you have the very complex and big code with no use of understanding all other languages which are with simple code are useless and only java has the long syntax and it's very best even print in python and printf cout do the same thing as system.out.println it's a simple common sense make it simple for Java creators developers it makes sense to understand it demotivates when you see writing this long verbose code every single time I'm so tried sir I request please make a video like how to address our language issues to the java developers who modify and bring changes to the language I'm very serious of these modifications must happen in Java sir thank you for making this video and informing regarding this it's a good news to know but I hope you understood our pain as what we feel as beginner we are in the era of making a language simpler and easier like python where java is still the language with those long verbose syntax and statements with no modifications
It's a great feature introduced in java 21. And I really like the frequency of how they are releasing new versions with lesser coding features. Hopefully in the next few years we have to write a java one liner command as in the normal English language.😂
In few years, the java we know will be deprecated. 😂
it's good thing they are trying to simplify it for new incomers. There are 30 years of features that might feel overwhelming for a newcomer.
Java needs simple way to create simple apps while keeping its capability for big scalable projects.
I'd like to see also another disadvantages of Java to be rid off though. Once you decide to make standalone app with UI from your so far within IDE app, you have to go through mountains and lakes to make it work if you have not done that before.
Any updates will come and go but we want only Telusko channel.
對於這項更新，我非常樂於嘗試與高興～😍
I am yours team lead to get this update in Java. Happy to see this!...
😂😂😂
It’s huge, hope previous code will still work perfectly when idk is upgraded
For me, the big feature that will be in java 21 is the virtual threads 🎉
You make my java learning path way more easier. Big salute sir.
I think it's a good but
every time we should start from
Basic understanding, so it's necessary to know public, static, void keywords before implementing any code....
Can it will run automatically without having a class name ?
Yes
@@Telusko okay 👍
Sir I need your reply.jam a new beginner from Cse diploma.how should i go through java to advance learner
Macbook contest made me a regular viewer of Telusko. The way you speak is Informative, Real and Natural. May God help Telusko to reach the heights...
Thanks a lot sir. At least people who are starting JAVA won't have to go with absolute Horrific code😂😂
Simplified things are easy to learn. For any newbie its very difficult to understand main method. Unnamed class.. Wow.. excited to learn how it will work..
Would it be nice to
the field mca sir?
Hi Navin , Can you please send the link to excel sheet that you showed , which has details of each Java Versions and its features
Hello sir, I am using java 17 for gradle and I want to install java latest version, so how can I use both version at a time? or their is any way to switch the version just like NVM. please help
Amazing for new learners or starters. This PSVM will get into our mind firstly when we learn java. So no more nightmares.
Sir it's good and I want some of yours videos on Stream and Lambda.
Hi sir , i know core Java concepts and i saw your 3 hour course on spring ....can i learn it directly or should i need to have some additional knowledge?
Hiee Actually I have to create Java program to create 4 folder 5,10,20,30 this is folder name after folder created after 5 sec in folder (5) file should create that file name should be current time after 10 sec file should create in folder (5,10)
After 20 sec file should create in folder (5,10,20) after 30 sec file should create in folder (5,10,20,30) after that execution should stop so finally folder 5 contains 4 file and folder 10 contains 3 file and folder 20 contains 2 file and folder 30 contains 1 file
Can anyone help me with a solution for this
Explained very well as usual!
What about migration? Won't it take lots of effort?
as a JAva trainer definitely felt it . But I would never show this to my students 🙈. My op. both updates source code runner and that simple code (except unnamed class and instance main) are useless.
Wonderful but after understanding all those concepts and learned trained on java for years by seeing that code make a happy moment but also make me uncomfortable that new code 1sec mind shock babu how do they did it without writing class & static,modifiers
It would be easy for the trainers, but for a fresher who starts with java for the first time, its would be better just to know about this update and to follow coding with the usual structure itself, so that he/she would be able to code with proper coding standards / structure going foward with Java.
But its really a great feature update as part of JDK21
But what is the main major use of this ?
No problem, java is still on the way to become a legacy language. New code if possible is written in kotlin.
Isnt there live session today?
Sir, Excellent this Java main method feature in JDK 21 and excellent your explanation. Finally we get rid of this thing (String[] args) 🤩. After all, thank you ❤.
Sir Make a video on java developer roadmap and carrier in java
they should also simplify System.out.println to println
and taking input from user easy like c++ and python
It is a nice move .It will help many to unlearn to learn. Kindly make some videos on java applets, swing, java FX, .From KENYA , I thank you for your efforts to help learners
Sorry my friend, but applets were deprecated (removed?) from Java.
It will great motivation for new learner’s
can youn explain java learners from basics please please
can you provide live class
If this feature was introduced 1 year before when I have started learning java, then I would suggest my friends to go with java instead of Python or Javascript. Because in java it feels like we are coding. 🥲🥲
I think this is the violation of the feature that :-
"EVERYTHING IN JAVA IS OBJECT."
Because if main() function is not wrapped by a class then how an object can be formed.
So, A trainer can't say that "everything in java is object" before showing the first hello world code because this is even harder to justify.
it is just syntax sugar. Compiler wraps it in a class at compile time.
I was waiting for "Interview questions" Live Day 7
public static void main(String args[]) to void main() wow fire
it looks good for new learners.
Brass have a golden shine but it's not gold....
Old is Gold
But in the end, It's of no use. In the beginning, it might help. Anyways! I think Java should focus on removing the primitive data types & concentrate on creating a Pure OOP Language by Only using Wrapper Classes. We don't need more features. Java has already loaded with it. But just tired of variations & lots of packages, inbuilt methods. It's time to organize & simplify the source code. Reply with your opinions too.
Wrapper classes😂
if anyone does freelancing please help!!!
i learend java and i love it.. i also learned html css and js.
i wanna start my freelancing journey where do i start ??
-should i learn spring ?? or nodejs??
i wanna earn some money......
you ll find more freelancing project in nodejs and it is easy compare to spring
@@chiragvohra6673 do you freelance ? Can I have you linked in please I need some guidance I am stuck.
Although I am a MERN stack developer however Java is love 😍
Its good for basic learners
Each redundant and overlapping feature added to any language makes more complicated and humongous.
psvm the life saver for java devs
sir mac cloud computing would be nice to do
it is very easy to learn
I think java still needs a lot of work to do jn future to compete with other languages
Awesome update
Great information #javawithcodegates
Sir colab with selelium express
Well it will make developers dumb, yeah get it it’s confusing at first but here’s the thing if you aren’t curious to know and find out what it is then you’re no good for development (my opinion); as a developer I am always curious like how does that work or what is is that helps me lot in learning new things and keep reading documentations that will be always lifesaver
But you see there are lots of boiler plate code ie verbosity leading to unnecessary extra number of lines ex getter, setters. kotlin/c# is much better to which java is catching up
Learnt Java from you❣️❣️❣️❣️
It is a good thing for beginners
Wow am thrilled 🎉🎉
python guys may dont have enough knowledge, but java devs surely have
As a Java trainer totally felt it 😂...
It's good 👍
I felt same when i started attending my first class in java
this will help for beginners.
I love Java.
You could be my best friend then😄
its becoming kotlin haha I start learning kotlin and is amazing Java thanks u for teach me master!
Nice update 😃
I also don't like it as java is very structured language. That is it's speciality, which will going to miss..
making students more lazy ! Ha Ha Ha
big fan of yours. from USA
Thank you bro!
kotlin got inspired and build by java and now java is inspired by kotlin
It looks great feature
They're in hurry to make it simple, they are overdoing it, its like changing English language, before a coder come to terms with existing code practices, they come up with new features, this tinkering with basic code can overwhelm and bring the coder to exhaustion, at least they should have some policy about not to touch basic code. This is simply not done, after investing so much time, energy and Efforts in learning the basics they are again changing it, terrible and sad!!!!!!!!!!!
Very nice
Pls don't scream it's not possible to listen.
Hii aliens 👽
Refreshed Memories of void main in C
Update was awesome
demn jshell is great
It's like c
Java want to replace python and mojo soon
Java comeback soon
Every 6 month they give me reasons to hate java more than ever
It's only for first time listeners 😂
bhai seeddhe update bata deta 😅😂😂
Its good 👍
Hello world is universal program 😂
unnamed classes... ftw... XD
Not impressed with the approach Oracle is taking to make learning Java simple
Java is dead after 8. Currently, than further than crazier.
Bad
I don't like it without class 🥲
Its not compulsory to follow new syntax
@@Telusko You are my real guru....Love from Tamil Nadu sir ❤️
