I asked this question before but the answer was hand written and I couldn't understand the hand writing so I'm reposting. Question: Inheritance binds the classes closer together This is an example of trading-off increased coupling in exchange for reduced code duplication. Sometimes composition can achieve (perhaps somewhat less) reduction in code duplication while minimizing coupling between classes. Give an example pair of classes with two variations: one using inheritance and one using composition. Discuss the pros and cons.
