+equals(o:Object):boolean (A)

Automobile

+equals(o:Object):boolean (B)
+equals(o:Automobile):boolean (C)





Sedan Minivan

+equals(Object o):boolean (D) +equals(Object o):boolean (G)
+equals(o:Automobile):boolean ( E) +equals(o:Automobile):boolean (H)
+equals(o:Sedan):boolean (F) +equals(o:Minivan):boolean (I)

This is dynamic binding
