How to parse JSON in Java
(36 answers)
Closed 9 months ago.
so I have, I doing a program that receives a string json with an unknown structure (since it's a variable each time I receive a new one) and it needs to parse the string to extract each key and its type (from its value).
I need to do this using only java (no spring) because I've seen solution using Jackson tree, but with the software I'm using it impossible
If someone could help I would appreciate it.
You can use JSONObject from org.json library .

How to convert POJO to JSON and vice versa?

"testing":{"infixSuggester":{
"Sample":{
"numFound":10,
"suggestions":[{
"term":"test",
"weight":0,
"payload":""},
{
"term":",
"weight":0,
"payload":""}
I want this JSON to convert it into a POJO Class. Can anyone suggest how to do it? where "Sample" is the string value which is creating dynamically.
Seems like Gson or Jackson can do the trick: https://stackabuse.com/how-to-convert-json-object-to-java-object-with-jackson/

I am trying to make a discord bot that parses a json response, but I'm not entirely sure on how to do so.
This is an example response:
[{"beatmap_id":"146929","score":"1467874","maxcombo":"182","count50":"1","count100":"41","count300":"475","countmiss":"10","countkatu":"20","countgeki":"72","perfect":"0","enabled_mods":"0","user_id":"1009","date":"2020-02-29 11:15:49","rank":"A","pp":"38.767826"},{"beatmap_id":"245658","score":"1013358","maxcombo":"244","count50":"0","count100":"6","count300":"158","countmiss":"1","countkatu":"5","countgeki":"24","perfect":"0","enabled_mods":"0","user_id":"1009","date":"2020-02-29 11:13:05","rank":"A","pp":"49.74563"},{"beatmap_id":"245658","score":"34162","maxcombo":"42","count50":"0","count100":"1","count300":"27","countmiss":"1","countkatu":"0","countgeki":"4","perfect":"0","enabled_mods":"0","user_id":"1009","date":"2020-02-29 11:12:19","rank":"A","pp":"12.399677"},{"beatmap_id":"1128411","score":"4785282","maxcombo":"350","count50":"23","count100":"292","count300":"1117","countmiss":"51","countkatu":"93","countgeki":"132","perfect":"0","enabled_mods":"0","user_id":"1009","date":"2020-02-29 11:10:52","rank":"C","pp":"12.770388"},{"beatmap_id":"431147","score":"209504","maxcombo":"105","count50":"0","count100":"4","count300":"73","countmiss":"1","countkatu":"3","countgeki":"9","perfect":"0","enabled_mods":"0","user_id":"1009","date":"2020-02-29 11:04:05","rank":"A","pp":"22.695227"}]
How would I just get the first "beatmap_id" key and return the value of it with Gson?
I'm fairly new to coding and I need a push in the right direction, so could someone give me an example, or link me to the part of the documentation i need to learn this?
Any help is appreciated, thanks!
You should create DTO class for same followed by keys which are in the response.
You can view this blog for understanding gson.

That is not well-formed JSON. For a start, you have multiple attributes with the same name. There's no Java JSON library that could represent that.
