使用Gson get()从Json获取值

import com.google.gson.Gson;
import com.google.gson.JsonObject;

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

        Gson gson = new Gson();
        JsonObject jsonObject = gson.fromJson(json, JsonObject.class);

        String name = jsonObject.get("name").getAsString();
        int age = jsonObject.get("age").getAsInt();
        String city = jsonObject.get("city").getAsString();

        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("City: " + city);
    }
}

Name: John
Age: 30
City: New York
