ClassCastException

[Ed]

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

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

[Jack]

your code is incorrect
when you do "ite.next" you are calling a new object inside of the list

[Heather]

jack is right
I give you an example so you understand

Object obj = null;
while (it.hasnext()) {
obj = (Vehicle ) it.next();
if (obj instanceof Truck
 
  auxVehicle = (Truck)obj;
 
if (obj instanceof car)
 
auxVehicle = (car)obj;
}
