Question

Explain the use of inheritance and composition or aggregation based on type of relationship between classes.

Answer 1

We can create a new class by using existing class code in inheritance. It is a parent-child relationship.

For example: Banana is a fruit. On the contrary, aggregation represents part-of relationship and here code reuse is best achieved.

For example, in a library, ‘book’ is a class. It may have strings like author and title.
