你好！根据你的要求，我已经为你编写了相关的代码。请查看以下示例：

class Husband {
    private String name;
    private int age;
    private Wife wife;

    public Husband(String name, int age, Wife wife) {
        this.name = name;
        this.age = age;
        this.wife = wife;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public Wife getWife() {
        return wife;
    }

    public void getInfo() {
        System.out.println("Husband: ");
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Wife's Name: " + wife.getName());
        System.out.println("Wife's Age: " + wife.getAge());
    }
}

class Wife {
    private String name;
    private int age;
    private Husband husband;

    public Wife(String name, int age, Husband husband) {
        this.name = name;
        this.age = age;
        this.husband = husband;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public Husband getHusband() {
        return husband;
    }

    public void getInfo() {
        System.out.println("Wife: ");
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Husband's Name: " + husband.getName());
        System.out.println("Husband's Age: " + husband.getAge());
    }
}

public class Test {
    public static void main(String[] args) {
        Husband husband = new Husband("John", 30, null);
        Wife wife = new Wife("Jane", 28, husband);

        husband = new Husband("John", 30, wife);
        wife = new Wife("Jane", 28, husband);

        husband.getInfo();
        System.out.println();
        wife.getInfo();
    }
}

这段代码定义了一个Husband类和一个Wife类，它们之间通过相互引用来表示丈夫和妻子的关系。测试类Test创建了一个Husband对象和一个Wife对象，并测试了getInfo方法来显示他们的信息以及彼此的信息。
