WebOOP - Composition, Inheritance & Polymorphism. There are two ways to reuse existing classes, namely, composition and inheritance. With composition (aka aggregation ), you define a new class, which is composed of existing classes. With inheritance, you derive a new class based on an existing class, with modifications or extensions. 1.
