如何在java中使用ORG.JSON库从嵌套的JSONArrays中获取值？

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20210307</version>
</dependency>

String jsonStr = "{\"employees\": [{\"firstName\":\"John\", \"lastName\":\"Doe\"}, {\"firstName\":\"Anna\", \"lastName\":\"Smith\"}]}";

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class JsonParsingExample {
    public static void main(String[] args) {
        String jsonStr = "{\"employees\": [{\"firstName\":\"John\", \"lastName\":\"Doe\"}, {\"firstName\":\"Anna\", \"lastName\":\"Smith\"}]}";

        try {
            JSONObject jsonObj = new JSONObject(jsonStr);
            JSONArray employees = jsonObj.getJSONArray("employees");

            for (int i = 0; i < employees.length(); i++) {
                JSONObject employee = employees.getJSONObject(i);
                String firstName = employee.getString("firstName");
                String lastName = employee.getString("lastName");

                System.out.println("Employee " + (i + 1) + ": " + firstName + " " + lastName);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}

Employee 1: John Doe
Employee 2: Anna Smith
