I almost thought it is impossible to learn http requests in java from the internet until i saw this video, thanx man. Great video by the way

[superiorautism]

Dan, thank you so much for this tutorial!
I'm completely new to Java, and I feel that there are very few resources for learning these materials (compared to something like NodeJS or Python). It's greatly appreciated!

Nice! Lot's of API's out there with data returned in JSON format - this tutorial is exactly what I needed to get started! Learning about the .forEach was also a bit of a bonus. I think all I need to do is find this done asynchronously and I'm all set ...

Great toturial man thanks.

Could you please make a toturial for Post method ?
specially for this scenario :

- Post a Json object ( which include user and pass)
- get the value for token in response body.

[abigailedwards]

Thanks man. Great tutorial!

Have you ever thought about a new video about Spring boot + GraphQl or Spring boot + GraphQl + security?

I think it's a great topic for 2020.

Is it possible to map the response with body handler itself ?

[pajeetsingh]

Do you think adding application related functionality directly into a programming language somehow defeat incentive to learn the language itself?

[michaelnewman]

This may be a dumb question, but what if you only need to access a few specific fields of your Json object? For instance if I was using a geocoding api and only needed to return the latitude and longitude. Thanks for the video extremely helpful!

Is it possible to set multiple headers in our GET/POST method? In my program I need to set the authorization header (basicAuth), and I wonder if I can also set the content type.
