Java 1.4serializable error

An instance of this class is thrown if when an assertion fails. This happens when assertions are enabled, and the expression following an assert statement does not evaluate to true. If an assertion fails, and the assert statement has a second expression separated from the first by a colon, then the second expression is evaluated and the resulting value is passed to the AssertionError( ) constructor, where it is converted to a string and used as the error message.
