JDK to create a program JRE libraries needed to run the program JVM converts the bytecode to a machine instructions

[@soma7891]

Perfectly summarized.

[@FIatts]

This is actually extremely helpful, thank you.

[@a55tech]

but JRE can run the program, so doesn't it overlap with JVM? Still not clear what's the difference.

[@bubbleteaichooseyou]

@@a55tech so base on what I understand, the reason why you feel JVM and JRE are overlapping is because JVM itself is also a part of JRE which in basic word mean JRE is JVM and more. JVM alone might not necessarily able to run everything which it need assistant from JRE. Correct me if I'm wrong since I'm not sure about that myself

[@a55tech]

@@bubbleteaichooseyou i think it mean JRE is JVM + other shit like libraries or something to run stuff

[@likithr.n9692]

I've gone through his udemy course, believe me, you don't need anything else to master java apart from his course He's simply brilliant.

[@Geminis3505]

Thank you so so much for the video explaining the differences between JDK, JRE, and JVM. I really appreciate it!!!

[@isurujn]

I've always been confused about these 3. Thanks for this video. Very well explained.

[@steve-n1738]

This is hands down the best explanation on the internet.

[@smooth8580]

no cap

[@WanderingNasi]

JRE = Joe Rogan Experience. I think I'm at the wrong place...

[@suraj.mohapatra]

definitely you were at the wrong place.

[@AbhishekSingh-xg3zj]

Thanks a ton sir for giving such beautiful explanation ❤. Keep making such awesome videos on such core Computer Science concepts

[@reshmag7825]

I purchased your Java Programming course in Udemy. Its excellent. 😇. So happy to see you here

[@Jiawii]

So Java Runtime Edition and Java Runtime Environment are actually the same thing?

[@vezeveer]

There is no Java Runtime Edition...

[@spiralni]

No runtime Edition. U mean Java Standard Edition?

[@FerventRebutter]

@@vezeveer No, there isn't, but Tim keeps swapping between the two.

[@ipishka]

best explanation ever! thank you!

[@amlanalok]

I loved this video. I have crystal clear clarity after watching this.

[@antonrhein5527]

A great introduction for any aspiring developer. Thanks for your efforts ! :)

[@RameenFallschirmjager]

I love learning java with aussie accent!

[@MukeshKumar-tu9iw]

great explanation sir 👏👏

[@Spooky_man]

2:20 : It has been years... Finally I found my explaination! Oracle DID NOT make Java "pay to use"

[@senthilkumaran5317]

Great and clear explanation of the concept.

[@MK-ro4ue]

This is a great introduction video. I appreciate it! It would be great if you can create a video which goes in more depth about these general concepts (or even class lecture on udemy or similar, I think lot of people would be more then rather to subscribe to those - I know I would). 1. General implementations of JVM - history - which language is used for JVM implementations to run compiled java code (since we have multiple VM implementations, common oracle written in c++ ). There are multiple compilers as well (common one is the javac compiler by oracle that is mainly written in C) ... why multiple of them .. how? Beef between google and oracle :) (dalvik vs oracle vm ... ) what is happening there from perspective of tech details ... 2. Now when OracleJDK is "subscribe on" and when you need to pay for it... what kind of ifferences we have between openJDK and OracleJDK speed wise .. Based on my limited knowledge about this subject, i saw that there is a decent amount of difference based on the benchmark results ... - is openJDK suitable for programming enterprise scale softwares (especially network related microservices across multiple machines) ? Even maybe to explain subscription principle (per core, machine etc ... in more details, based on example ... this part is extremely confusing ... eg. if you have x amount of machines with 2 core processor each running java, how much you need to pay per month?) I think those twos above are interesting subjects - and it would be great if you can shed some light on those :)

[@TheLearnProgrammingChannel]

Thanks for the suggestions. I'll see what I can come up with in the future!

[@ugqueen]

Easy to follow! I always refer back to this!

[@bassamkhalid3478]

I study that all high-level languages are platform independent but not operating system independent , what is the defference between that and java independence ?

[@bassamkhalid3478]

I hope to get an answer

[@bassamkhalid3478]

Unfortunately I haven't found it yet

[@A1ex-]

very well explained, thanks

[@soma7891]

So JVM is platform dependent?

[@AlamKhan-tg4mr]

Yes, JVM takes the byte code, and generates executable for the current operating system. Java language by itself is platform independent.

[@progtom7585]

very good video, thanks mate.

[@bambooflute5158]

I want to run small old java based program in my computer but I am scared that Java is unsafe. How can I handle this? Out of JDK, JRE and JVM whic one is safe?

[@newDawn-u4l]

Im a fan of you sir

[@kevinbenavides92]

Thank you!

[@AhamedKabeer-wn1jb]

Thank you..

[@Km-pn3hf]

спасибо

[@manavacharya5916]

I had to check if I had the playback speed to normal or not XD

[@FIatts]

Well I know JRE stands for Joe Rogan Experience so I already got one of them down

[@MrVirkMedia]

🥇 gold

[@pritamsarkar4041]

It was totally incorrigible and rendezvous

[@gambarimas]

What is the Java Runtime Edition you said ?

[@michaligocki35]

nothing. Tim fucked up, he meant Java Runtime Environment and didn't correct himself.

[@LouisaWright-n3c]

[@luisbarahona3773]

Hi Tim, do you have an intermediate level java course?

[@TheLearnProgrammingChannel]

I have data structures and algorithms, advanced algorithms and search algorithms courses - they are not beginner courses - see all my udemy courses here lpa.dev/courses/y

[@vicp8210]

You are like reading a document. How you got that many reviews in Udemy ?

[@MusTy57]

I lost 3 hours to understand this video. I want to thank you for your effort and I want to add one thing; if you are explaining these words what they are why are you using these hard sentences such as "abstract computing machine...". Please keep your explanations like simplifying stuff. You are throwing other words which makes us think about it for one hour...

[@TheLearnProgrammingChannel]

Thinking is good :) But yes I will keep that in mind for future videos!
