写一段yaml文件，并且给出对应的java实体类和解析类

以下是一个示例的YAML文件：

# example.yaml

person:
  name: John
  age: 30
  address:
    street: Elm Street
    city: Anytown
    state: CA
    zip: 12345

对应的Java实体类：

public class Person {
    private String name;
    private int age;
    private Address address;

    // getters and setters
}

public class Address {
    private String street;
    private String city;
    private String state;
    private int zip;

    // getters and setters
}

对应的解析类：

import org.yaml.snakeyaml.Yaml;

import java.io.InputStream;

public class YAMLParser {
    public static void main(String[] args) {
        Yaml yaml = new Yaml();
        InputStream inputStream = YAMLParser.class
                .getClassLoader()
                .getResourceAsStream("example.yaml");
        Person person = yaml.loadAs(inputStream, Person.class);
        System.out.println(person.getName());
    }
}

该解析类使用了`snakeyaml`库来读取YAML文件并将其转换为Java对象。在这个例子中，我们将`example.yaml`文件解析成了`Person`对象，并打印了人名。
