JSON.simple returns null, why? My JSON does have a keys corresponding to the json.get("key");
.
I followed a tutorial and my tree is similar to the tutorial's code. I have printed one of them just to debug, when printing the array values, it just prints out null for every json.get("key");
statment
My JSON:
{
"release": {
"version": "0.0.1 InDev",
"license": "GNU General Public License v3",
"LICENSE.txt?" : "Webber/LICENSE.txt",
"date" : "18th Februaru, 2022 @ 4:59PM Indian Standard Time",
"author" : "Habis Muhammed",
"contributors" : "***** 🙁 Nobody *****",
"libraries":"json-simple"
}
}
JSONObject json = (JSONObject) obj;
json = (JSONObject) json.get("release");
String version = (String) json.get("version");
You can try this. You have to traverse from JSON object root
