Question

Quizplus · Accepted Answer

The CashRegister class containing an array list of Coin objects can be best described as an example of aggregation. This is because the CashRegister class has a "has-a" relationship with the Coin objects, meaning it contains them as a part of its functionality, but the Coin objects can still exist independently outside of the CashRegister class. This is different from inheritance, where a class inherits properties and methods from a parent class, or cohesion, which refers to how well the elements within a class work together towards a common goal. Association refers to a relationship where one class is used by another but not as an integral part of its functionality.
