使用 Jackson，您可以使用 ObjectMapper 将 JSON 数据映射到 Java 对象，并访问其嵌套数组：
import com.fasterxml.jackson.databind.ObjectMapper;
class Person {
String name;
int age;
String[] skills;
String json = "{\"name\":\"John\",\"age\":30,\"skills\":[\"Java\",\"Python\",\"Javascript\"]}";
ObjectMapper mapper = new ObjectMapper();
Person person = mapper.readValue(json, Person.class);
System.out.println(person.name);
System.out.println(person.age);
System.out.println(person.skills[0]);
