Whenever im having a problem with Java etc. first I look for your tutorials!

[@gauravrajan7869]

The smile on your face clearly shows how much passionate you are about democratizing your learning.

[@fatuuxcade8655]

you really helped me to understand what is an API and XML/JSON. You explained as i want to understand. thanks

[@xilonmidi767]

And that's why you have half a million subscribers brother. Beautiful explanation. Some people are born to become teachers.

[@ShamanRing]

discovered your channel way too late. If I had discovered when I was at school, I would have learned programming much more effectively. You get right to the point, unlike most other channels.

[@youvegotmail9385]

I absolutely love this guy. He's so knowledgeable and I love how thorough his explanations are and he explains it in such a way where beginners won't get completely confused. His enthusiasm and energy really shines through his videos too, which keeps you engaged.

[@mohitsahoo7671]

You always make sessions interesting by giving different real time example which helps understanding the topic easily. Thanks Navin

[@mmkamal]

THE WAY YOU EXPLAIN IS SO EASY TO UNDERSTANDDDDDDDDD. THAAAANKS BRO

[@saraning498]

I really love your examples in all the videos I have watched so far! They are highly-relatable and make the concepts so easy to understand. Thanks for the effort!!!

[@akshayarolkar8259]

This clears off my REST API concepts; and thanks a lot for not playing any crappy music in the background like others. Love your energy. Much appreciated!!!!

[@watchmovie35]

Hats off!!! Finally I understood what is REST API and how is it used? Thank you Sir.

[@DevanshGaur]

This is one of the best explanation. Summary in layman's term: State of object = values of object We need to fetch an object's value not the object. That's why we have defined a JSON/XML format. In this format we receive the values of object that is state of objects.

[@cswalker21]

Love your videos sir, thank you so much. You have a way of taking things that are all jumbled up in my head and making them seem clear and logical. I'm very grateful for your efforts.

[@gurpreetapej]

I watched many videos' for REST API what exactly it is but none really tried to make it so simple and illustrative as you did ! I am network security engineer but i really wanted to understand the very basic of REST API ! You nailed the BASIC of REST API and anyone watching this video can easily understand the usage/example/structure of REST API ! Even the documentation available online did not help as much you helped ! Thank you very much from the Heart :) Moreover i noticed only Indian techies make complicated things look easy honestly as others will only explain in technical terms only like engineering books ! Simple RESTful explanation of REST API :) You were really able to explain the meaning of " representational state transfer "

[@ravisharma3007]

Am glad I found you, learning will be easier now :)

[@RamuChittiprolu]

Thanks much. Finally now I understand what is REST API.

[@GokulKarthickregency]

For Representation State Transfer : can we understand as we are taking a " snapshot of data of that Object " which is the Objects state at that moment.. which may keeps varying at the later point of time.. and transfering in either XML or JSON formats. so hence namingg with Acronym REST makes much sense as the state of that object is being transfered... please suggest whether my understanding is correct.

am just starting a project on intellij environment and would you pls help me on parsing XML to JSON... Thanks

[@TejaKarlapudi]

You do not parse XML to JSON. They both are two different formats. You pick one of the format and convert them into Objects by Parsing.

[@abhigyanraha5620]

You have to pick one format. Either JSON or XML

[@mayurkharat8998]

Brother, you forgot telling what is REST API ? , in all that talk.

[@harshvardhansinghgaharwar4950]

He tell already you dont listen

[@rentic888]

In short, when we request data instead of a web page from server, which in fact is a state of an object, we use REST API to receive that state of an object in xml/json format and by using REST API we do CRUD operations, and jersey and sparing is the way of implementing this REST API, i think this should make things clearer...

[@akhilapp1135]

@@rentic888 sir how will we implement REST API for getting state of an object instead of html web page?

[@sureshbabumaddula3005]

@@rentic888 nice explanation...

[@codegate615]

He really starts explaining it really at @8:03. It's very much related to the purpose of xml/json so that's why it may seem that way. It'd be nice if he showed an implementation, which is why you probably still don't quite get it.
