java - 让类(class)相互交换信息的最佳方式？

Question

假设我有 2 个类，House 和 Dog

我希望狗了解它所居住的房子，反之亦然。

我目前有这两个类(class)设置:

<小时/>

房屋类别:

public class House {

private String address;
private Dog dog;

public House(String address, Dog dog) {
    setAddress(address);
    setDog(dog);
    dog.setHouse(this);
}

public void setDog(Dog dog) {
    this.dog = dog;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public String getDog() {
    return dog.getName();
    }

}

狗类:

public class Dog {

private House house;
private String name;

public Dog(String name) {
    setName(name);
}

public void setHouse(House house) {
    this.house = house;
}

public String getHouse() {
    return house.getAddress();
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
    }

}

<小时/>

最后我有这个主类将它们连接在一起:

public class Main {

public static void main(String[] args) {

    Dog dog = new Dog("Alex");
    House house = new House("123 Main street", dog);

    System.out.println(dog.getName() + " resides in " + dog.getHouse());
    System.out.println(house.getAddress() + " has a dog named " + house.getDog());

    }

}

控制台输出:

Alex resides in 123 Main street
123 Main street has a dog named Alex

<小时/>

我本质上想知道是否有更好的方法让这两个类在彼此之间交换数据/信息。我觉得我现在所拥有的可能非常困惑/草率，并且可能不是良好的设计实践。欢迎任何反馈/建议。

谢谢

我想你要找的东西在 this: Managing Bidirectional Associations in my Java Model 中这个问题恰好有其他有用的堆栈溢出答案的链接。
