Constructor Summary

Constructors

Constructor	Description
ExceptionInInitializerError()	Constructs an ExceptionInInitializerError with null as its detail message string and with no saved throwable object.
ExceptionInInitializerError(String s)	Constructs an ExceptionInInitializerError with the specified detail message string.
ExceptionInInitializerError(Throwable thrown)	Constructs a new ExceptionInInitializerError class by saving a reference to the Throwable object thrown for later retrieval by the getException() method.

Method Summary

Modifier and Type	Method	Description
Throwable	getException()	Returns the exception that occurred during a static initialization that caused this error to be created.

Modifier and Type	Method	Description
final void	addSuppressed(Throwable exception)	The specified exception is going to be suppressed in order to give priority to this exception (primary exception) and to be appended to the list of suppressed exceptions.
Throwable	fillInStackTrace()	Record in the receiver a walkback from the point where this message was sent.
Throwable	getCause()	Answers the cause of this Throwable, or null if there is no cause.
String	getLocalizedMessage()	Answers the extra information message which was provided when the throwable was created.
String	getMessage()	Answers the extra information message which was provided when the throwable was created.
StackTraceElement[]	getStackTrace()	Answers an array of StackTraceElement.
final Throwable[]	getSuppressed()	Returns an array of exceptions suppressed, typically by the automatically generated code from the try-with-resources statement, in order to give priority to this exception (primary exception).
Throwable	initCause(Throwable throwable)	Initialize the cause of the receiver.
void	printStackTrace()	Outputs a printable representation of the receiver's walkback on the System.err stream.
void	printStackTrace(PrintStream err)	Outputs a printable representation of the receiver's walkback on the stream specified by the argument.
void	printStackTrace(PrintWriter err)	Outputs a printable representation of the receiver's walkback on the writer specified by the argument.
void	setStackTrace(StackTraceElement[] trace)	Sets the array of StackTraceElements.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.

clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

ExceptionInInitializerError

public 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

public 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 - The exception thrown

ExceptionInInitializerError

public 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 Throwable.getMessage() method. There is no saved throwable object.

Parameters:

s - the detail message

Method Details

getException

public Throwable getException()

Returns the exception that occurred during a static initialization that caused this error to be created.

API Note:

This method predates the general-purpose exception chaining facility. The Throwable.getCause() method is now the preferred means of obtaining this information.

Returns:

the saved throwable object of this ExceptionInInitializerError, or null if this ExceptionInInitializerError has no saved throwable object.
