The code below shows: 

JavaApplication1.java:34: error: non-static method get(Object) cannot be referenced from a static context

JSONArray cars = (JSONArray) JSONObject.get("cars");                                                      

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Iterator;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

public class JavaApplication1 {

    @SuppressWarnings("unchecked")
    public static void main(String[] args) {

        JSONParser parser = new JSONParser();

        try {
            JSONArray a = (JSONArray) parser.parse(new FileReader("C:/Users/Glambert/Dropbox/java/New folder/perfection/UPdate/json.txt"));

            for (Object o : a)
            {
                JSONObject person = (JSONObject) o;

                String name = (String) person.get("name");
                System.out.println(name);

                String city = (String) person.get("city");
                System.out.println(city);

                String job = (String) person.get("job");
                System.out.println(job);

                JSONArray cars = (JSONArray) JSONObject.get("cars");

                for (Object c : cars)
                {
                    System.out.println(c+"");
                }
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}

Anyone has any idea why this is the case?

(by the way, this code was found online and I edited it to test run, so that I can create a new code to take in a different kind of txt file.)

  • If the code was found on line, you should credit the original author and link to where you found it. – RealSkeptic Oct 29 '15 at 12:54

Check this line 

 JSONArray cars = (JSONArray) JSONObject.get("cars");

change it with 

 JSONArray cars = (JSONArray) person.get("cars");

Issue was since you are calling the get method directly on the class.
