Try this:

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
...
Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonParser jp = new JsonParser();
JsonElement je = jp.parse(json.toString());
String prettyJsonString = gson.toJson(je);
System.out.println(prettyJsonString);

Output:

{
  "sensor_key": "6f2159f998",
  "from": "2016/08/29 16:55:00",
  "to": "2016/08/29 17:05:00",
  "metrics": "1st data",
  "time_zone": "Mumbai",
  "per": "50"
}

Probabbly, you should use the same solution: Pretty-Print JSON in Java

Also, GSON is quite good overall
