Java Inheritance Has-A Relationship (Person) | What is Has-A Relationship in Java Inheritance?

In Java, the Has-A relationship refers to a class having another class as one of its members or fields. It signifies that an object of one class "has" another object of another class. For example, if a Person class has an Address field, we can say that Person "has" an Address.

In the context of Java inheritance, the Has-A relationship is often implemented using composition, where one class contains an instance of another class. This allows for code reuse, better organization, and more maintainable code.

In the "Java Inheritance Has-A Relationship (Person)" tutorial, we'll explore how to implement the Has-A relationship using the Person class as an example. We'll create a Person class that contains an Address object, demonstrating how the Person class "has" an Address.

1. Explanation of Has-A relationship in Java inheritance
2. Understanding the concept of composition
3. Creating a Person class with an Address field
4. Implementing the Has-A relationship using composition
5. Example code walkthrough
