What do you mean by "show polymorphism"?
In Java, all instance methods are polymorphic.

You can infer polymorphism in places. When you see B inherit from A or implement interface A, you get a strong clue hint polymorphic behavior is desired. When you see a parameter declared as A and then look in the class hierarchy and see a number of classes inherit from A or implement A, same thing.
 
Don't get me started about those stupid light bulbs.
