How do you know if an explicit object casting is needed?
How do you know if an explicit object casting is needed?
✍: Guest
If you assign a superclass object to a variable of a subclass's data type, you need to do explicit casting. For example:
Object a; Customer b; b = (Customer) a;
When you assign a subclass to a variable having a supeclass type, the casting is performed automatically.
