使用json.simple在单行中解析JSONObject中的JSONObject

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

String jsonString = "{\"name\":\"John\",\"age\":30,\"address\":{\"street\":\"123 Main St\",\"city\":\"New York\"}}";
JSONObject json = (JSONObject) new JSONParser().parse(jsonString);

JSONObject address = (JSONObject) json.get("address");

String street = (String) address.get("street");
String city = (String) address.get("city");

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

public class JsonParsingExample {
    public static void main(String[] args) {
        String jsonString = "{\"name\":\"John\",\"age\":30,\"address\":{\"street\":\"123 Main St\",\"city\":\"New York\"}}";
        
        try {
            JSONObject json = (JSONObject) new JSONParser().parse(jsonString);
            JSONObject address = (JSONObject) json.get("address");
            
            String street = (String) address.get("street");
            String city = (String) address.get("city");
            
            System.out.println("Street: " + street);
            System.out.println("City: " + city);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}
