public class RuntimeException
extends Exception

This is the base-class of all unchecked exceptions. Unchecked exceptions do not need to be declared in the method signatur and the compiler does not enforce that a handler is defined for them.

RuntimeExceptions normally occur as a bug in a program and they are often not recoverable by the user.
