Class ExceptionInInitializerError

    java.lang.Object
      java.lang.Throwable
          java.lang.Error
              java.lang.LinkageError
                  java.lang.ExceptionInInitializerError

All Implemented Interfaces:
  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

  Serialized Form

Constructor Summary
`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
`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.

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 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 Detail

### getException

    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.

### getCause

    public Throwable getCause()

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

  Overrides:
    `getCause` in class `Throwable`
  Returns:
    the cause of this error or `null` if the cause is nonexistent or unknown.

    1.4
