+Brijesh Yadav *South Indian accent.

[@SINHASAMEER]

I had been going crazy to understand the difference between them from some time. You explained it in a very efficient manner. Thanks for clearing the concepts

[@shubhamkhadbade5327]

💞

[@pmbhagat077]

read few books... few blogs / web pages.... and watched few videos on java.
this is the first (and I guess last video one needs to watch) I watched that cleared all my doubts about JDK, JRE and JVM. you are simply great Durga sir. wish you had training center here in Mumbai too.

[@rafaelruales6871]

I didn't understand a lot of the things he said, however, somehow, now I understand the difference!! thanks!

[@umermustafa2560]

He is such a genius concept directly went into my brain through my skull and made space for itself..

[@81_monish_roy74]

Durga sir's teaching is like a bottle of wine. With time it gets more and more understandable. Thank you sir. You are a gem of India

[@shivendrapandey9918]

Perfect.. Understood the concept
JDK is a kit So it Allows both Compilation(JDK\bin -- > Javac ) and Execution (JDK\bin -- > java),
Since JRE for only for Run time Env, So it allows only execution(JRE\bin -- > java).

[@princeagyeifrimpong9889]

No wonder all the best students in my class are from Asia ... I watched the video and understood it properly 🙏🏽🙏🏽... God Bless you Durga

[@Icecodes]

heartiest thanks sir

[@hirakmondal6174]

*_JRE_* : Java Runtime Environment. It is basically the Java Virtual Machine where your Java programs run on. It also includes browser plugins for Applet execution.
*_JDK_* : It's the full featured Software Development Kit for Java, including JRE, and the compilers and tools (like JavaDoc, and Java Debugger) to create and compile programs.
Usually, when you only care about running Java programs on your browser or computer you will only install JRE. It's all you need. On the other hand, if you are planning to do some Java programming, you will also need JDK.
Sometimes, even though you are not planning to do any Java Development on a computer, you still need the JDK installed. For example, if you are deploying a WebApp with JSP, you are technically just running Java Programs inside the application server. Why would you need JDK then? Because application server will convert JSP into Servlets and use JDK to compile the servlets. I am sure there might be more examples.

[@venkatkrishna266]

you should not teach this to a beginner

[@vaibhavshukla1054]

Thanks Hirak it made things more clear to me.

[@viveksukhla8631]

In JVM, we have JIT compiler but you are saying JVM is like interpreter. What is the use of JIT compiler in JVM?

[@pradeepchandra7045]

+Ravindra Chary Palakonda
jvm is a interpreter it reads line by line code and executes so it is time consuming inorder to speed up the processes we use jit compiler so execution time of the code is reduced

Good teaching

[@RahulGupta-ly2uu]

sir ur telling that jvm is interpreter but sir when we compile .java file then we are going to compile whole file at once and create the respective class file and then we are going to run the whole program at once by using that class file
if it is an interpreter then we should not bother about compiling .java file
if we are compiling and if their is an error then it should execute the lines before that error occurred but in real time it is not behaving like that why sir??
pz answer to me sir or anyone

[@urvbu27sh864]

Rahul Gupta dear bro...
JVM is neither compiler nor interpreter on a single but JVM contains jit compiler (just in time compiler) and interpreter both and both these components works simultaneously to give results from .java to .Class file....
And later display the results..
Hope u got ur facts cleared...

[@johnpremkumar9552]

I guess JVM interprets only the already compiled code by java compiler.
