Java如何使用流去除集合中某个字段为空的对象

public class Person {
    private Integer id;
    private String name;
    private String sex;
    private String email;
    private Long phoneNumber;
    private String personUuid;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public Long getPhoneNumber() {
        return phoneNumber;
    }
    public void setPhoneNumber(Long phoneNumber) {
        this.phoneNumber = phoneNumber;
    }
    public String getPersonUuid() {
        return personUuid;
    }
    public void setPersonUuid(String personUuid) {
        this.personUuid = personUuid;
    }
    public Person() {
    }
    public Person(Integer id, String name, String sex, String email, Long phoneNumber, String personUuid) {
        this.id = id;
        this.name = name;
        this.sex = sex;
        this.email = email;
        this.phoneNumber = phoneNumber;
        this.personUuid = personUuid;
    }
    @Override
    public String toString() {
        return "Person{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", sex='" + sex + '\'' +

                ", personUuid='" + personUuid + '\'' +
                '}';
    }
}
