JSONArray转java的list

可以使用Gson库将JSONArray转换为Java的List。具体实现代码如下：

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import org.json.JSONArray;

import java.lang.reflect.Type;
import java.util.List;

public class JsonArrayToList {
    public static void main(String[] args) {
        String jsonArrayStr = "[{\"name\":\"Tom\",\"age\":18},{\"name\":\"Jerry\",\"age\":20}]";
        JSONArray jsonArray = new JSONArray(jsonArrayStr);

        Gson gson = new Gson();
        Type type = new TypeToken<List<Person>>(){}.getType();
        List<Person> personList = gson.fromJson(jsonArray.toString(), type);

        System.out.println(personList);
    }
}

class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}
