在Java 8中遍历2个对象和1个嵌套对象

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

    // 构造函数、getter和setter方法省略

    // 内部类Address
    class Address {
        private String city;
        private String street;

        // 构造函数、getter和setter方法省略
    }
}

List<Person> persons = new ArrayList<>();
persons.add(new Person("John", 25, new Person.Address("New York", "123 Main St")));
persons.add(new Person("Jane", 30, new Person.Address("London", "456 Park Ave")));

persons.stream()
    .forEach(person -> {
        System.out.println("Name: " + person.getName());
        System.out.println("Age: " + person.getAge());
        System.out.println("Address: " + person.getAddress().getCity() + ", " + person.getAddress().getStreet());
        System.out.println();
    });
