Which statement in main() generates an error?
Sunny_sXe [5.5K]

Answer:

C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.

Explanation:

The main method in this code will case an error when trying to run the following line of code...

leagueName=newPlayers.getLeague();

This is because the method getLeague() is being called on a Player object which takes all of its methods from the Player class. Since getLeague() is not a method located in the player class then it cannot be called by an object from that class. Especially since the Player class does not extend to the SoccerPlayers class where the getLeague() method is actually located. Instead, it is the SoccerPlayers class which extends the Players class as its parent class.
