Composition (called “has-a�) is a relationship between classes where one class has a data member that is an instance of the other class, such as “a car has a tire�. When creating a program, you need to choose whether to relate classes through inheritance or composition.

hi all,

with regard to composition and inheritance, there is a term named as polymorphism...is it related to the above? so infact, composition is inheritance, but in my class, we usually called the method as inheritance and the sub-classes have the attributes and properties of the main class. i mean from the main-class, u will have the sub-classes and the relationship is called inheritance. hope that what i understand can be of use to you. cheers!
