Question
What is the primary purpose of the composition relationship in a class diagram?a.To indicate a dependency between two classesb.To model a bidirectional relationship between classesc.To represent a strong form of association where the lifespan of the contained object depends on the containerd.To denote a unidirectional association between classes
Solution
The primary purpose of the composition relationship in a class diagram is to represent a strong form of association where the lifespan of the contained object depends on the container. This means that if the container is destroyed, the contained object will also be destroyed. This relationship is often used to represent real-world relationships where one object is a part of another object. For example, a car is composed of an engine, wheels, and other parts. If the car is destroyed, the engine, wheels, and other parts are also destroyed.
