Class Error
java.lang.Error
All Implemented Interfaces:
Direct Known Subclasses:
public class Error
An
Error is a subclass of
Throwable
that indicates serious problems that a reasonable application
should not try to catch. Most such errors are abnormal conditions.
The
ThreadDeath error, though a "normal" condition,
is also a subclass of
Error because most applications
should not try to catch it.
A method is not required to declare in its throws
clause any subclasses of Error that might be thrown
during the execution of the method but not caught, since these
errors are abnormal conditions that should never occur.
That is, Error and its subclasses are regarded as unchecked
exceptions for the purposes of compile-time checking of exceptions.

Constructs a new error with
null as its detail message.
The cause is not initialized, and may subsequently be initialized by a
call to
Throwable.initCause(Throwable).
Constructs a new error with the specified detail message. The
cause is not initialized, and may subsequently be initialized by
a call to
Throwable.initCause(Throwable).
Parameters:
message - the detail message. The detail message is saved for
later retrieval by the
Throwable.getMessage() method.
Constructs a new error with the specified detail message and
cause.
Note that the detail message associated with
cause is not automatically incorporated in
this error's detail message.
Parameters:
message - the detail message (which is saved for later retrieval
by the
Throwable.getMessage() method).
cause - the cause (which is saved for later retrieval by the
Throwable.getCause() method). (A
null value is
permitted, and indicates that the cause is nonexistent or
unknown.)

1.4
Constructs a new error with the specified cause and a detail
message of
(cause==null ? null : cause.toString()) (which
typically contains the class and detail message of
cause).
This constructor is useful for errors that are little more than
wrappers for other throwables.
Parameters:
cause - the cause (which is saved for later retrieval by the
Throwable.getCause() method). (A
null value is
permitted, and indicates that the cause is nonexistent or
unknown.)
Since:
1.4
protected Error |
( String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) |
Constructs a new error with the specified detail message,
cause, suppression enabled or disabled, and writable stack
trace enabled or disabled.
Parameters:
message - the detail message.
cause - the cause. (A null value is permitted,
and indicates that the cause is nonexistent or unknown.)
enableSuppression - whether or not suppression is enabled
or disabled
writableStackTrace - whether or not the stack trace should
be writable
