Explain composition.
What will be an ideal response?
A class can contain objects of another class as data members. For example, you might create a class named Date that contains a month, day, and year, and add two Date fields to an Employee class to hold the Employee's birth date and hire date. Then you might create a class named Department that represents every department in a company, and create each Department class member to contain a supervisor, who is an Employee. When a class contains objects of another class, the relationship is called a whole-part relationship or composition. The relationship created is also called a has-a relationship because one class "has an" instance of another.
