测试

public class TestPersonBuilder {
    public static void main(String[] args) {
        Person person = new Person.PersonBuilder("花花", 20)
                .sex("男")
                .interest("钢琴")
                .profession("作家")
                .build();
        System.out.println(person.toString());
    }
}
