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 {@link #getException()} method is now known as the cause, and may be accessed via the {@link Throwable#getCause()} method, as well as the aforementioned "legacy method."

private static final long
serialVersionUID
Use serialVersionUID from JDK 1.1.X for interoperability
private Throwable
exception
This field holds the exception if the ExceptionInInitializerError(Throwable thrown) constructor was used to instantiate the object
Constructors Summary
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.


                                     
      
        initCause(null);  // Disallow subsequent initCause
public ExceptionInInitializerError(Throwable thrown)
Constructs a new ExceptionInInitializerError class by saving a reference to the Throwable object thrown for later retrieval by the {@link #getException()} method. The detail message string is set to null.

param
thrown The exception thrown

        initCause(null);  // Disallow subsequent initCause
	this.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 {@link Throwable#getMessage()} method. There is no saved throwable object.

param
s the detail message

	super(s);
        initCause(null);  // Disallow subsequent initCause
Methods Summary
public java.lang.ThrowablegetCause()
Returns the cause of this error (the exception that occurred during a static initialization that caused this error to be created).

return
the cause of this error or null if the cause is nonexistent or unknown.
since
1.4

	return exception;
public java.lang.ThrowablegetException()
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 {@link Throwable#getCause()} method is now the preferred means of obtaining this information.

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

	return exception;
