I did an iterator
I have different objects
Some of them are cars, and other trucks (both of them are subclass of Vehicles )
When I iterate in every element of the vector
this error appears:

ClassCastException

this is my code

Code:

while it.hastnext()
 
if (it.next() instanceof truck
 
  auxVehicle = (truck)it.next();
 
if (it.next() instanceof Car
 
auxVehicle = (Auto)it.next();
