I read some articles written on "ClassCastException", but I couldn't get a good idea on that. Is there a good article or what would be a brief explanation?
Straight from the API Specifications for the
Thrown to indicate that the code has attempted to cast an object to a subclass of which it is not an instance.
So, for example, when one tries to cast an
Integer to a
String is not an subclass of
Integer, so a
ClassCastException will be thrown.
Object i = Integer.valueOf(42); String s = (String)i; // ClassCastException thrown here.
