I have this JSON string but I don't know how to reach the "snow" value from the list in "preciptype".

{
    "currentConditions": { 
        "preciptype": ["snow"]
    }
}

I have tried the following:

String precipitations;

JSONObject currentConditions = new JSONObject("currentConditions");

precipitations = currentConditions.getString("preciptype");

I know this is not the right solution because "preciptype" is not a string, but I can't wrap my head around how to get "snow" from there. I even tried to loop through it, but it was not working either.

CodePudding user response：

To get the "snow" value from the list in "preciptype", you can use the getJSONArray method to get the list as a JSONArray object, and then use the getString method to get the value at a particular index. Here's an example of how you can do this:

package test.test;

import java.io.FileReader;
import java.io.IOException;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import org.json.JSONTokener;

public class App {
    public static void main(String[] args) {
        String filePath = "D:\\Documents\\workspace\\test\\test\\src\\main\\resources\\test\\test\\test.json";
        try (FileReader reader = new FileReader(filePath)) {
            JSONTokener tokener = new JSONTokener(reader);
            JSONObject json = new JSONObject(tokener);
            JSONObject currentConditions = json.getJSONObject("currentConditions");
            JSONArray preciptype = currentConditions.getJSONArray("preciptype");
            String precipitation = preciptype.getString(0);
            System.out.println(precipitation); // prints "snow"
        } catch (IOException e) {
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}
