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.

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.

Error	back to summary
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. Parameters message:String the detail message (which is saved for later retrieval by the `getMessage()` method). cause:Throwable the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) Since 1.4

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.

Parameters

message:String: the detail message (which is saved for later retrieval by the getMessage() method).
cause:Throwable: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Error back to summary

Error	back to summary
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. Parameters cause:Throwable the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) Since 1.4

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.

Parameters

cause:Throwable: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

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:String the detail message. cause:Throwable the cause. (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.) enableSuppression:boolean whether or not suppression is enabled or disabled writableStackTrace:boolean whether or not the stack trace should be writable Since 1.7

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:String: the detail message.
cause:Throwable: the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
enableSuppression:boolean: whether or not suppression is enabled or disabled
