Give an example of an is-a (inheritance) relationship and a separate example of a has-a (composition) relationship within the fields of either mathematics, biology, or engineering. the example should be different from one given in class. explain why these are appropriate examples.

Inheritance (is-a) relationships are derived child classes that inherit attributes and methods from their parent class. Composition (has-a) relationships are classes whose attributes are comprised of other classes. Each relationship has its advantages and disadvantages. See the link below for best uses of each.

For example:

class Animal { }

class Dog extends Animal { }

This means Dog IS-A animal

2. HAS-A simply means reference

For example:

class Nip { }

class Dog { private Nip nip;}

This means Dog HAS-A Nip

Hope this helped!! :)
