POHow to set up bidirectional association between two objects in OO Java
text
Body
copied!<p>I have a basic assignment to do but am very new to OOP and struggling with it. Other online resources are starting to add to my confusion.</p> <p>I am required to:</p> <ol> <li><p>Write code for a class Person. A Person object is to have attributes name, age and address.</p></li> <li><p>Write code for a class Dog. A Dog object is to have attributes name and age. </p></li> <li><p>Give any additional code in the Person and Dog classes that is required to setup a bidirectional association between a Person object and a Dog object. A Person object acts as an owner for a Dog object and the Dog object acts as a pet for the Person object. </p></li> <li><p>Modify your Person class so that a Person object can act as owner for up to 20 Dog objects.</p></li> </ol> <p>Obviously this is a very simple example.</p> <p>My <strong>code</strong> so far: </p> <p><em>Person Class :</em></p> <pre><code> public class Person { // instance variables - replace the example below with your own private String name; private int age; private String address; /** * Constructor for objects of class Person */ public Person() { this.name = name; this.age = age; this.address = address; } //Set Methods: public void setName () { this.name = name; } public void setAge () { this.age = age; } public void setAddress () { this.address = address; } //Get Methods: public String getName () { return name; } public int getAge () { return age; } public String getAddress () { return address; } } </code></pre> <p><em>Dog Class:</em> </p> <pre><code> public class Dog { // instance variables - replace the example below with your own private String name; private int age; public Dog() { this.name = name; this.age = age; } //Set Methods: public void setName () { this.name = name; } public void setAge () { this.age = age; } //Get Methods: public String getName () { return name; } public int getAge () { return age; } } </code></pre> <p><em>Main:</em> </p> <pre><code>public class Main { //Blank } </code></pre> <p>I know this code is currently useless and doesn't do anything but I am unsure of how to 'associate' the objects & where to do it. The assignment spec specifies a person acts as an 'owner' for the dog. </p> <p>This is where my problem lies. Setting up the relationship between the objects. </p>
