[@parildoshi6004]

Really liked the way you teach the topic with test cases with the best industry level practices.

[@SuperCoderFromScratch]

Thanks so much !

[@MrKrishnasinghal]

This is such a good video, Idk why people didnt comment ques and ans instead of all that.

[@JustinDouglas-j4m]

hi im new to all of this but this code is giving me a error. public class Json { private static ObjectMapper objectMapper = getDefaultObjectMapper(); private static ObjectMapper getDefaultObjectMapper() { ObjectMapper defaultObjectMapper = new ObjectMapper(); return defaultObjectMapper; } public static JsonNode parse(String src) throws IOException { return ObjectMapper.readTree(src); } } Non-static method 'readTree(java.lang.String)' cannot be referenced from a static context. any help is appreciated

[@SuperCoderFromScratch]

Hey, how is it going? Sorry for taking so long to reply. Have you checked this tutorial repository? The code there should still work.

[@JustinDouglas-j4m]

@@SuperCoderFromScratch Hey bro, i have not checked it but i did find the issue. i was trying to call the object instead of it's instance which led to my error. Thnx for helping appreciate it.

Brilliant first part to the tutorial! Great work!

[@SuperCoderFromScratch]

Thanks so much !

hi, iam getting the error: "Definieren Sie die Hauptmethode als: public static void main(String[] args):" am i missing launching the app from "public static void main(String[] args) from anywhere in your tutorial?

[@SuperCoderFromScratch]

Yes, you maybe are. The reason is the code is basically ran from tests if I remember correctly. You can use obviously the classes in program, but you need to provide the program. Does this make sense ?

[@roary4092]

Thank you for making this video, found it very informative.

Hey @Roary529 !!! Thanks so much for the feedback!

If json file contains any nonascii character like a french letter 'e how to parse it throws exception

[@SuperCoderFromScratch]

Can you open an issue at: github.com/CoderFromScratch/json-in-java-tutorial ? Need to see that exception and know which systems you are running this in.

Thanks man !

[@nirajchowdhary7372]

I believe when you write assertEquals, "Coder from scratch" will come as the first parameter and getting value from node tree as second. I know it does not matter but just mentioning it since i noticed that. assertEquals(expected, actual) is the convention. BTW great video :D

[@SuperCoderFromScratch]

You are absolutly correct.

[@ChazWinter]

It always bothers me when people switch them around hahaha

[@blackheat8]

You’re a tremendous help. Thank you!!

[@SuperCoderFromScratch]

You are so welcome! Thanks for the feedback!

[@markthomas9641]

Great video, thank you. DeltaJSON is really useful if you are working with JSON, it does compare, merge and graft.

[@yaroslavprozorov]

Thanks man, you did really a good job

[@SuperCoderFromScratch]

Thanks so much for the feedback, I really do appreciate it!

[@unfinishedsentenc9864]

I really liked the tutorial. I just wish that you would increase font size or zoom in while typing. It is very difficult to read.

[@SuperCoderFromScratch]

Than ks for the feedback! Will work on this !

[@ibrahimothman366]

can't I use intellij builder ?

[@SuperCoderFromScratch]

You can but then you would need to add the libs you are dependent on manually as dependencies. Doing it through maven just saves time.

Sure can. Check out the github: github.com/CoderFromScratch/json-in-java-tutorial . Is this the droid you are looking for?

video is good but use light theme because many a times its difficult to watch

[@SuperCoderFromScratch]

Thanks so much for the feedback! I'll try to keep that in mind in the following videos !

Thanks

Excellent

Thank you so much 😀

[@260Lipe]

My god so much work for a JSON :(

[@SuperCoderFromScratch]

Not really, just if you want to map json objects to pojos. If you don't need or want to do that, there are other ways.

[@catlord69]

You dont have to type the main method, just type main and intellij creates it for you !

[@SuperCoderFromScratch]

Oh yes :) Thanks for the tip. Its one of those things I already do automatically. Creating a main method is not something I do on a regular basis, so didn't know about that shortcut.

[@catlord69]

@@SuperCoderFromScratch handy one for sure :)

[@ragnarlothbrok367]

Too complicated, overkill

[@SuperCoderFromScratch]

Thanks for the feedback!

[@ruqersa1066]

still worth it for eclipse ?

[@SuperCoderFromScratch]

Sure ... it is just an IDE. You can do this on Notepad if you want. Think of eclipse and intellij as text editors on steroids.
