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.

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.
