Koushik, you have a rare talent. Technical expertise, but the ability to teach in an easily understandable way. I've watched many of your courses and all of it is clear and well structured. Many thanks, you have helped me so much in what I do day to day at work.
Today was my interview with one of the companies and they asked me the difference between post and put /Get and Post,I could not answer accurately. After watching this video I can answer about these 4 HTTP methods anytime in the future. Thanks for so nice explanation !!!
Interviewer asked me question about Difference between put and Post..and I could not answered that time. Later I search on google it and tried to understand it, but couldn't. But today after seen this tutorial I fully understood difference between HTTP methods. Thanks Java Brains for Such Excellent Tutorial.
Thank you sir, you're a blessing to the Java community. I'm a fresher into the industry and I look fwd to helping others just like you, after I've gained enough experience.
This guy is Awesome! Hats off to you Koushik. Amazing Videos n equally Amazing way to Decipher the Hidden Nuances behind each and every important peace of information.
so clear precise and in slow motion, even if i didn't want to understand this by the time i was finished watching i understand this whole concept of the idempotence means. it was being explained in such a thoughtful manner anyone can understand this. Great job great video. this is post being sent as a non idempotence (will not be duplicating this ) ; ).
you are blessed with excellent voice and the accent is just right.... can hear you for hourssssssss.... thank you so much ... pls keep up the good work...
ProTip: Use the same shirt on ALL videos of a series. So ppl feel the continuum. ProTip2: Allow youtube adds man, no hard feelings. U deserver the extra income.
You listen to this person & watch his videos & you will up & ready to work on the technology/concepts not known to you before watching his videos. As rightly said HTTP methods are specifications & it is good to follow these during the implementation & these are just the names given to the kind of operation one does. So actual behavior depends on the requirements/constraints. POST is used to create the resource, & as generally told that it is non-idempotent & we call it multiple times it will create multiple such resources. But if I think about creation of the profile in the system & possibly will be using POST call, but will I be able to create multiple profiles with same data? No...So I think, any method/operation making any changes in the system can't be idempotent purely & other factors need to be considered & it is conditional.
DELETE is idempotent *under certain conditions*. For instance, in your example if the ID in the request isn't a primary key (e.g. for whatever reason, resources are being created with the first available ID, rather than incrementing from the highest ID ever used), then you can run the risk of timing issues like deleting different resources that had been assigned the same ID. Likewise, if the API allows non-unique criteria to define the target resources (e.g. matching text strings), you can also get differing results from repetition of the same request. It's also important to note that idempotence doesn't guarantee resource identicality in the real world. If you have two conflicting and repeating PUT requests going to the same resource, you end up going back and forth between the two values being written. This is when you can start to get timing issues accessing a resource that is flipping between different values in a tug of war between requests.
Say suppose i'm storing the updated_time of a post. So if i do multiple PUT requests, the post content stays same, but the "updated_time" will be changed. So how can we call the PUT request Idempotent?
Thanks. I keep getting asked about the difference between post and put on job interviews, but could never really answer that question properly. Also, I now realize I've been abusing post in REST APIs... Well, I've learned for future projects.
The word update has the letter 'U' like PUT, it has 'U' too but Post does not has 'U' thats mean PUT causes update (both have 'U') but Post does not. your Tutorials are great
Superb explanation and screen I really learn a lot from your tutorial videos Thanks a lot....your teaching methods is extremely awesome....hope for your more real time videos....Thanks again for making those video lecture and hard work :) while I creating Comment I remember your Post http method and while updating i remember Put http method - Vj
I have a doubt, let's say I want to delete the last element from a list, if I use DELETE it is not going to be idempotent (Because in the first call, y delete one element, in the next call another, and so on) what method should I use?
Man! The way you explain things makes me feel saluting you. There are only a handful of people on earth with such a gift as yours. RESPECT!
@@AshrafMMA what you mean by exercises.
even after 6 years this video series is like a gem in the ocean.

Very nice explanation for REST methods. Thanks for KT. Keep it up...
Simple topic but cleared out a lot of my question! Many thanks!
Say suppose i'm storing the updated_time of a post.
So if i do multiple PUT requests, the post content stays same, but the "updated_time" will be changed.
So how can we call the PUT request Idempotent?
Thanks. I keep getting asked about the difference between post and put on job interviews, but could never really answer that question properly.
Also, I now realize I've been abusing post in REST APIs...
Well, I've learned for future projects.
Excellent explanation about Http verbs..
The word update has the letter 'U' like PUT, it has 'U' too but Post does not has 'U' thats mean PUT causes update (both have 'U') but Post does not. your Tutorials are great
Thanks Koushik for making learning so easy :)
Superb explanation and screen I really learn a lot from your tutorial videos Thanks a lot....your teaching methods is extremely awesome....hope for your more real time videos....Thanks again for making those video lecture and hard work :)
while I creating Comment I remember your Post http method and while updating i remember Put http method - Vj
Very good explanation. Thanks. Waiting for another one.
