The relationships are the structure of the object. has-a
relationship can be described in Java code as member fields.
is-a relationship can be described in Java keyword extends.
The is-a relationship has an inheritance feature (like
"extends" or "implements") and has-a relationship has an
encapsulation feature (like private or protected modifier
used before each member field or method).

Let's look at one example. Translate the following perfect
sentences into Java code.

1. Pizza is a food. A Pizza has ingredients, a cost, and
a price.


public class Pizza extends Food //is-a relationship
{
int ingredients;//has-a relationship
double cost;
double price;
....
}
