使用Java内置的JSON库orgjson写个解析取字符串demo加上抛出异常

import org.json.*;

public class JSONParserDemo { public static void main(String[] args) { String jsonString = "{"name":"John","age":30,"city":"New York"}";

    try {
        JSONObject jsonObject = new JSONObject(jsonString);
        String name = jsonObject.getString("name");
        int age = jsonObject.getInt("age");
        String city = jsonObject.getString("city");

        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("City: " + city);
    } catch (JSONException e) {
        System.out.println("Error parsing JSON string: " + e.getMessage());
    }
