ExceptionInInitializerError

public class ExceptionInInitializerError extends LinkageError

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 Throwable.getCause() method, as well as the aforementioned "legacy method."

Public Constructor Summary

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

Public Method Summary

Throwable	getCause() Returns the cause of this error (the exception that occurred during a static initialization that caused this error to be created).
Throwable	getException() Returns the exception that occurred during a static initialization that caused this error to be created.

Inherited Method Summary

From class java.lang.Throwable

synchronized final void	addSuppressed(Throwable exception) Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
synchronized Throwable	fillInStackTrace() Fills in the execution stack trace.
synchronized Throwable	getCause() Returns the cause of this throwable or `null` if the cause is nonexistent or unknown.
String	getLocalizedMessage() Creates a localized description of this throwable.
String	getMessage() Returns the detail message string of this throwable.
StackTraceElement[]	getStackTrace() Provides programmatic access to the stack trace information printed by `printStackTrace()`.
synchronized final Throwable[]	getSuppressed() Returns an array containing all of the exceptions that were suppressed, typically by the `try`-with-resources statement, in order to deliver this exception.
synchronized Throwable	initCause(Throwable cause) Initializes the cause of this throwable to the specified value.
void	printStackTrace() Prints this throwable and its backtrace to the standard error stream.
void	printStackTrace(PrintWriter s) Prints this throwable and its backtrace to the specified print writer.
void	printStackTrace(PrintStream s) Prints this throwable and its backtrace to the specified print stream.
void	setStackTrace(StackTraceElement[] stackTrace) Sets the stack trace elements that will be returned by `getStackTrace()` and printed by `printStackTrace()` and related methods.
String	toString() Returns a short description of this throwable.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.

Public Constructors

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.

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

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

Public Methods

public Throwable getCause ()

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

Returns

the cause of this error or null if the cause is nonexistent or unknown.

public 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 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.
