如何使用GSON将JSON反序列化为不同字段的对象

import com.google.gson.Gson;

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

        // 创建GSON实例
        Gson gson = new Gson();

        // 反序列化JSON为Person对象
        Person person = gson.fromJson(json, Person.class);

        // 输出Person对象的字段值
        System.out.println("Name: " + person.getName());
        System.out.println("Age: " + person.getAge());
        System.out.println("City: " + person.getCity());
    }
}

class Person {
    private String name;
    private int age;
    private String city;

    // Getter和Setter方法

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
}
