  Serializable

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."
Since:
JDK1.1

• • Constructor Detail

     * #### 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](../../java/lang/Throwable.html "class in java.lang") thrown)  
     Constructs a new `ExceptionInInitializerError` class by saving a reference to the `Throwable` object thrown for later retrieval by the [getException()](../../java/lang/ExceptionInInitializerError.html#getException--) method. The detail message string is set to `null`.  
     Parameters:  
     `thrown` \- The exception thrown  
     * #### ExceptionInInitializerError  
     public ExceptionInInitializerError([String](../../java/lang/String.html "class in java.lang") 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()](../../java/lang/Throwable.html#getMessage--) method. There is no saved throwable object.  
     Parameters:  
     `s` \- the detail message  

  • Method Detail

    * #### getException  
    public [Throwable](../../java/lang/Throwable.html "class in java.lang") 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()](../../java/lang/Throwable.html#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.  
    * #### getCause  
    public [Throwable](../../java/lang/Throwable.html "class in java.lang") getCause()  
    Returns the cause of this error (the exception that occurred during a static initialization that caused this error to be created).  
    Overrides:  
    `[getCause](../../java/lang/Throwable.html#getCause--)` in class `[Throwable](../../java/lang/Throwable.html "class in java.lang")`  
    Returns:  
    the cause of this error or `null` if the cause is nonexistent or unknown.  
    Since:  
    1.4
