java.lang.ClassCastException

Question

Normally whats the reason to get java.lang.ClassCastException ..? I get the following error in my application

java.lang.ClassCastException: [Lcom.rsa.authag         


        

Answer 1

It's because you're casting to the wrong thing - you're trying to convert to a particular type, and the object that your express refers to is incompatible with that type. For example:

Object x = "this is a string";
InputStream y = (InputStream) x; // This will throw ClassCastException

If you could provide a code sample, that would really help...
