The JIT doesn't avoid compiling the repeated lines of code. It replaces the already compiled code in place of the repeated lines instead of compiling the same code again and again.
I would guess that what is presented in the video is just a simplification, and that the JIT would detect runtime redundancies that the compiler is not able to detect remove without potentially messing up the program.
Thank you for the compliments Bhakti, I am glad that I could make this JIT topic easy for you. please do share the videos with your friends too. Thats the biggest help and support 😇
After watching this video , I got clarity on the purpose of JIT compiler. Great work ! Btw how are you making these videos , especially to create content in single page. Videoscribe or any other softwares used?
Really good explanation, but even after watching your video I had some doubts, resovling them I came across the fact that ; when the jvm uses the jit compilation the interpretation process is completely skipped. The jit produces the native machine code directly, which is ready to be executed.
According to what he mentioned in the video, JIT compiler just transfers the non redundant code to the interpreter but if the JIT compiler is used before the compiler in the compile stage, if any error occurs in the program especially in the redundant code lines, the compiler throws an error only for one redundant line as it can't see the remaining lines, it's quite a problem if those redundant lines are at random positions.......for example: out of 1000 code lines there are 300 redundant lines JIT passes 701 code lines so compiler throws error only for that one redundant line( in case of error with redundant lines) so it's tedious to search for the rest. In case if it's used after compiler, I guess result remains the same, so it doesn't makes any difference.
This is a great video! But I do have a question. Why do things like duplicated lines of code have to be caught by the JIT compiler? Can't the first compiler catch those?
as I understand from the video they are different, the first compiler act on java code it checks syntax errors and code duplication for example before converting it to bytecode. the second compiler act on bytecode (ABC.class) its optimize the bytecode to make the program run faster (like in the video it removes the duplication of set the same value to the same variable) before sending it to the interpreter to convert it to native machine code to run on CPU
@@OudoMohy Are you saying that JIT is part of the main compiler? From what I understand, the main compiler compiles the java code to bytecode, then the bytecode is given to the users, then the JIT compiles and runs the program on the user's computer
In one of the interview of FAANG companies, I was being asked very deep internal working of all these steps. Is there any book that I can read for such details.
Thank you so much buddy, I am glad to hear this from you. Please do share the videos with your friends & Definitely SUBSCRIBE. Thats the biggest help & support 😇✌
Thats really great to know buddy🙏 Please support me by sharing the videos and our channel with your friends too. Thats the biggest help and support you can provide 😇
You're welcome Bhawna. Glad to hear your positive feedback. Please do share the video with your friends and contacts too. That will be super helpful 😋😇
Thanks bro 🤟 well to be honest I never ever opened any book for studying and programming language. Everything you'll get on Google. You can refer javatpoint website. 🤟
so JDK compiles the code and converts it into bytecode. The bytecode is further loaded, verified and executed in JVM also JVM provides a runtime environment. so what does JRE do ???
The .class file itself is a bytecode . If we assume the byte code is executed line by line by Interpreter or the JIT compiler what is the format of the output that is being generated?
Hi Mr. Simple, i love your explanation, but i don't understand, can we choose to use JIT or not? and will jit run only if there is a code update ? and if there is no code update then the JIT will not run and will go directly to the interpreter ?.. please sir this make me so confused

Oh, great. NOW I do understand. Thank you for being so clear and precize
I am non IT,learning java,wanted to know about JIT. You nailed it.
Thank you for the compliments Bhakti, I am glad that I could make this JIT topic easy for you. please do share the videos with your friends too. Thats the biggest help and support 😇
Thank you...and you're amazing at using the cursor to write text and boxes.
Most welcome buddy. Glad to hear this from you. I use Digital Tab & pen for the black board explanations 😇
Skipped my class and watched this
After watching this video , I got clarity on the purpose of JIT compiler. Great work !
Btw how are you making these videos , especially to create content in single page.
Videoscribe or any other softwares used?
I am glad this video helped you understand the working of JIT compiler. I am making this videos using smoothdraw4 software for drawing. ✌
thanks a lot for this wonderful video !!! was very educational

Awesome work bro I never heard before about JIT THANKS
Thank you so much for the positive response buddy. And yeah JIT compiler is one of the major reasons for Java code being high performance 😇✌️
Hey Tanmay, thanks for this one!
You’re way of explaining stuff is really good.
Simply and Smoothly explained :)
Woww ✌🏼
thank you sir great explaination amazing keep it going you just nailed it great work yrr
Thats great to know Darshana. Please do share the videos with your friends too. Thats the biggest help and support you can provide ✌
Totally manifested 🙌❣️
valuable explanation about java execution .. thank u
Thank you so much for the positive feedback. Do share the videos with your friends and contacts too 😇🙏
Thanks buddy..superb explanation..
Thank you so much bro. I would request you to please share the videos with your friends too. That'll be the best help and support for everyone 😇✌️
Nice explain
I have a question, if the JIT is to remove the redundant code, why don’t we do this at compile stage. Doesn’t it make more sense?
According to what he mentioned in the video, JIT compiler just transfers the non redundant code to the interpreter but if the JIT compiler is used before the compiler in the compile stage, if any error occurs in the program especially in the redundant code lines, the compiler throws an error only for one redundant line as it can't see the remaining lines, it's quite a problem if those redundant lines are at random positions.......for example: out of 1000 code lines there are 300 redundant lines JIT passes 701 code lines so compiler throws error only for that one redundant line( in case of error with redundant lines) so it's tedious to search for the rest. In case if it's used after compiler, I guess result remains the same, so it doesn't makes any difference.
Explanation is very good.🙏🙏

Great work 👏👏 ...ur simple snippets bringing a great change
Thanks a lot 😊
It's clearly understanding tq sir
bro what a explanation bro
great work bro
thanks a lot
You're most welcome bro. I am glad that you liked it. Please support me by sharing the video with your friends too :-)
Great Explanation.....thank you so much....
Love u sir😍😍🙏🙏🙏🙏❤️

Perfectly explained!
Amazing explaination bro ❤
what a explanation bro !!!!!!!!!!!!!!!!+++++++++++++++++!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! God bless you

Awesome Content Sir.
Just one question which textbook do you refer/recommend to understand java ?
Thanks bro 🤟 well to be honest I never ever opened any book for studying and programming language. Everything you'll get on Google. You can refer javatpoint website. 🤟
great video bro
Excellent 👌🔥
Thanks Tanay 🔥
Nice sir.
Спасибо, очень познавательно и полезно
Добро пожаловать, я рад слышать это от вас. Пожалуйста, поделитесь видео с друзьями тоже✌
so JDK compiles the code and converts it into bytecode.
The bytecode is further loaded, verified and executed in JVM also JVM provides a runtime environment.
so what does JRE do ???
was very helpful.. thanks alot.. Peace!!!!!!!!!
his explaination way is greate but even after he didn't get so much views as compared to others isn't?
Help me by sharing this video with your friends if you think it will be helpful for everyone 🙏
So the JIT will work on the code optimization process
Nice Video
The .class file itself is a bytecode . If we assume the byte code is executed line by line by Interpreter or the JIT compiler what is the format of the output that is being generated?
Nice

Hi Mr. Simple, i love your explanation, but i don't understand, can we choose to use JIT or not? and will jit run only if there is a code update ? and if there is no code update then the JIT will not run and will go directly to the interpreter ?.. please sir this make me so confused
Nice video!
But I had a doubt, how does JRE fit into all of this?
💖
is the existence of JIT depends on the version of JDK?
Yes, since Java 1.2 java had a JIT compiler
What is JAR?
can we assign b=7 two times?
how JIT does it please explain in detail

I need a shoutout plssssssssssss
Good explanation
