Signals that an unexpected exception has occurred in a static initializer.
An ExceptionInInitializerError
is thrown to indicate that an
exception occurred during evaluation of a static initializer or the
initializer for a static variable.
As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. The "saved throwable
object" that may be provided at construction time and accessed via
the getException()
method is now known as the cause,
and may be accessed via the getCause()
method, as well
as the aforementioned "legacy method."

ExceptionInInitializerError ()
Constructs an ExceptionInInitializerError
with
null
as its detail message string and with no saved
throwable object.
A detail message is a String that describes this particular exception.
ExceptionInInitializerError (Throwable thrown)
Constructs a new ExceptionInInitializerError
class by
saving a reference to the Throwable
object thrown for
later retrieval by the getException()
method. The detail
message string is set to null
.
Parameters | |
---|---|
thrown |
Throwable :
The exception thrown
|
ExceptionInInitializerError (String s)
Constructs an ExceptionInInitializerError with the specified detail
message string. A detail message is a String that describes this
particular exception. The detail message string is saved for later
retrieval by the getMessage()
method. There is no
saved throwable object.
Parameters | |
---|---|
s |
String :
the detail message
|
Throwable getCause ()
Returns the cause of this error (the exception that occurred during a static initialization that caused this error to be created).
Returns | |
---|---|
Throwable |
the cause of this error or null if the
cause is nonexistent or unknown. |
Throwable getException ()
Returns the exception that occurred during a static initialization that caused this error to be created.
This method predates the general-purpose exception chaining facility.
The getCause()
method is now the preferred means of
obtaining this information.
Returns | |
---|---|
Throwable |
the saved throwable object of this
ExceptionInInitializerError , or null
if this ExceptionInInitializerError has no saved
throwable object.
