Does the attached code answer this question?

Complete the code for the Player and Team classes. Each class must derive from the Entity class, as demonstrated in the UML diagram.

Every team and player must have a unique name by searching for the supplied name prior to adding the new instance. Use the iterator pattern in the addTeam$()$ and addPlayer$()$ methods.
