@John.... Why don't you make video's on Spring boot?It would be really helpful for us

@wyilt998 Год назад

I support 100%. John's Spring Boot video is sorely missed

@pranavnyavanandi9710 Год назад

Can you tell mhat that is? Spring boot..?

@hackersmethod3340 Год назад

@@pranavnyavanandi9710.... Can't you google it???You should learn how to google

@Foxsterdota Год назад

Yeah a video on the basics of e.g. Spring Boot would be a logical continuation

@k283535 Год назад

I support 👍✅

@pesterenan Год назад

I'm impressed. You just taught the basics of REST API concepts, and then showed how to basically build the app from the ground up, while also mentioning several "complicated" topics, but in a simple and understandable way. I loved it! Already subbed!

@UnfinishedYara Год назад

Hey! I totally agree with what youre saying! His videos are really good, however, I have a question, what level do you think this is? Is this a beginner level kinda stuff or is it more advanced? If so how advanced is it really?

@pesterenan Год назад

@@UnfinishedYara I believe this is somewhat a beginner level. If you're developing APIs you should know the basics of what was showed here. But don't stress it too much, I'm in an internship and it's been 7 months and only now I'm seeing about REST APIs.

Crystal clear explanation of the concepts. This exactly align with what we do in our day to day office work. Thank you John and keep making these kind of videos. 👏🏼👏🏼👏🏼

You have such an amazing Talent to break complicated stuff down in an easy understandable way. I showed some of your Videos my co workers and we all agreed that for example your Lambda Video was More understandable than everything we heard until that video. Same goes for this amazing api Tutorial. Thank you so much !!!

@kybkap8686 Год назад

Sir your way of teaching is legendary. Unfortunatley most of your videos are about core java. I hope you make more practical developing courses with different tools like this one. Thnx!

Hello John, beautifully explained! Thank you so much for your time and dedications for these videos

@itpugil Год назад

Thank you! Just what I needed because I was having a hard time making a GET request to Assembly AI because it keeps saying that my token is invalid. I placed it in the body rather than in the headers. Thank you for helping this novice out. Edit: Just finished the video. Even though I am writing a similar program using python, it was great to see him explain how to do it in java. This was what I was looking for because the documentation in Assembly AI's website was not that clear for me, like the part where you need to go to headers and set the token there etc.

Hello John, first of all wanted to thank you. I love your videos, it is the best I found on RU-vid to learn Java. Could you make a video on how to actually code the REST API? I think it is really useful and a lot of people will be interested. Other topics which I would love to learn about are: -Docker -Database Connection -CLI apps Thank you!

As a Junior QA Engineer using Java this channel has helped me so much to learn new stuff in a crystal clear way that makes my job a lot easier. Thank you so much John for what you are providing. Could you perhaps help understand how this could be achieved if you are using GraphQL requests? Also, is there a version of an extension, such as Boomerang but for Edge?
