如何构造类，使其可用于反序列化具有嵌套元素的JSON字符串

public class MyClass {
    private String name;
    private int age;
    private List<NestedClass> nestedElements;

    // Getter and Setter methods

    public static class NestedClass {
        private String nestedName;
        private int nestedValue;

        // Getter and Setter methods
    }

    public static void main(String[] args) {
        String jsonString = "{\"name\":\"John\",\"age\":30,\"nestedElements\":[{\"nestedName\":\"Nested\",\"nestedValue\":42}]}";

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            MyClass myClass = objectMapper.readValue(jsonString, MyClass.class);
            System.out.println(myClass.getName());
            System.out.println(myClass.getAge());
            List<NestedClass> nestedElements = myClass.getNestedElements();
            for (NestedClass nestedElement : nestedElements) {
                System.out.println(nestedElement.getNestedName());
                System.out.println(nestedElement.getNestedValue());
            }
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }
}
