public class RuntimeException extends Exception
RuntimeExceptionis the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.
RuntimeException and its subclasses are unchecked
exceptions. Unchecked exceptions do not need to be
declared in a method or constructor's
throws clause if they
can be thrown by the execution of the method or constructor and
propagate outside the method or constructor boundary.
