Query a JSONObject in java

by

I’ve just unexpectedly found very interesting project: JSON Path

JsonPath is to JSON what XPATH is to XML, a simple way to extract parts of a given document.

With this library you can do what you are requesting even easier, then my previous suggestion:

String hello = JsonPath.read(json, "$.data.data2.value");

System.out.println(hello); //prints hello

Hope this might be helpful either.
