Why cannot cast Integer to String in java?

Question

I found some strange exception:

java.lang.ClassCastException: java.lang.Integer 
 cannot be cast to java.lang.String

How it can be possible

Answer 1

Objects can be converted to a string using the toString() method:

String myString = myIntegerObject.toString();

There is no such rule about casting. For casting to work, the object must actually be of the type you're casting to.
