public class Error extends Throwable
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.

message - the detail message. The detail message is saved for later retrieval by the
Throwable.getMessage() method.

Note that the detail message associated with cause is not automatically incorporated in this error's detail message.
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.)
public Error(Throwablecause)
(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.
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.)
protected Error(Stringmessage, Throwable cause, boolean enableSuppression, boolean writableStackTrace)
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
