记得下载这个包Gson

import java.util.List;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;

public class main{

    public static void main ( String[] args ){
        String jsonData = "[{" + 
        "\"courseID\": \"AAS 100\"," + 
        "\"courseName\": \"Intro Asian American Studies\"," +
        "\"instructors\": [\"Ngo, F\"]" +
        "}, {" +
        "\"courseID\": \"ACCY 301\"," +
        "\"courseName\": \"Atg Measurement & Disclosure\"," +
        "\"instructors\": [\"Sougiannis, T\", \"Wang, Z\", \"Anderson, S\", \"Li, W\"]" +
        "}]";

        Gson gson = new Gson();
        List jsonList = gson.fromJson(jsonData, new TypeToken<List>() {
        }.getType());

        System.out.print(jsonList.toString());

    }
}
