We decided to create two additional classes on top of the required classes:

1. Account
2. Page

All of the objects in this project each have a

• Name
• Image
• equals()
• Getters & Setters for name & image

in their object. Therefore, it would be redundant to rewrite these in every single class, so this one master class would ensure minimal repetition. Additionally, because all of the objects need to override the default Object's equals() method, when we compare 2 objects we just had to see if they were downcasts of Page, in order to implement our special method of comparision. This makes our method a lot cleaner, because then we don't have a switch making sure that the object that we are comparing actually contains a name attribute.

We realized that the Person and Pet class had a lot of attributes and methods in common, such as

• Friends
• Moments
• getFriendWithWhomIAmHappiest()
• getOverallHappiestMoment()
• findMaximumCliqueOfFriends()
• isClique()
• Getters & Setters for all attributes

Additionally, within the Moment class Pet and Person are treated as practically the same object. In fact, we used polymorphism in order to store Pet and Person in the same ArrayList.
