Class AssertionError
java.lang.Object
java.lang.Throwable
java.lang.Error
java.lang.AssertionError
- All Implemented Interfaces:
- Serializable
Thrown to indicate that an assertion has failed.
 
The seven one-argument public constructors provided by this class ensure that the assertion error returned by the invocation:
     new AssertionError(expression)
 
 has as its detail message the string conversion of
 expression (as defined in section 5.1.11 of
 The Java Language Specification),
 regardless of the type of expression.- Since:
