public class RuntimeException extends Exception
RuntimeException is 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.
| Constructor and Description |

Constructs a new runtime exception with
null as its
detail message. |
RuntimeException(String message)

|
RuntimeException(String message,
Throwable cause)
Constructs a new runtime exception with the specified detail message and
cause.

RuntimeException(Throwable cause)
Constructs a new runtime exception with the specified cause and a
