public class Error
extends Throwable

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.

构造器概要

构造器

限定符	构造器	说明
	Error()	Constructs a new error with null as its detail message.
	Error(String message)	Constructs a new error with the specified detail message.
	Error(String message, Throwable cause)	Constructs a new error with the specified detail message and cause.
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.
	Error(Throwable cause)	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).

构造器详细资料

Error

public Error()

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(java.lang.Throwable).

Error

public Error(String message)

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(java.lang.Throwable).

参数:

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

Error

public Error(String message,
             Throwable cause)

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.

参数:

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.)

Error

public Error(Throwable cause)

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.

参数:

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.)

Error

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.

参数:

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
