从java中的json项获取值

import org.json.JSONObject;

public class JsonExample {
    public static void main(String[] args) {
        // 示例JSON字符串
        String jsonString = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

        // 创建一个JSON对象
        JSONObject jsonObject = new JSONObject(jsonString);

        // 从JSON对象中获取特定的值
        String name = jsonObject.getString("name");
        int age = jsonObject.getInt("age");
        String city = jsonObject.getString("city");

        // 打印获取的值
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("City: " + city);
    }
}
