All Implemented Interfaces:
Serializable

An {@code Error} is a subclass of {@code Throwable} that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. The {@code ThreadDeath} error, though a "normal" condition, is also a subclass of {@code Error} because most applications should not try to catch it.

A method is not required to declare in its {@code throws} clause any subclasses of {@code 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, {@code Error} and its subclasses are regarded as unchecked exceptions for the purposes of compile-time checking of exceptions.

Field Summary
static final long	serialVersionUID

Constructor:

Constructor:
public Error() { super(); } Constructs a new error with {@code null} as its detail message. The cause is not initialized, and may subsequently be initialized by a call to #initCause .
public Error(String message) { super(message); } Constructs a new error with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to #initCause . Parameters: `message` - the detail message. The detail message is saved for later retrieval by the #getMessage() method.
public Error(Throwable cause) { super(cause); } Constructs a new error with the specified cause and a detail message of {@code (cause==null ? null : cause.toString())} (which typically contains the class and detail message of {@code 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 #getCause() method). (A {@code null} value is permitted, and indicates that the cause is nonexistent or unknown.) since: `1.4` -
public Error(String message, Throwable cause) { super(message, cause); } Constructs a new error with the specified detail message and cause. Note that the detail message associated with {@code cause} is not automatically incorporated in this error's detail message. Parameters: `message` - the detail message (which is saved for later retrieval by the #getMessage() method). `cause` - the cause (which is saved for later retrieval by the #getCause() method). (A {@code 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) { super(message, cause, enableSuppression, 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 {@code 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 since: `1.7` -

 public Error() {
        super();
}

Constructs a new error with {@code null} as its detail message. The cause is not initialized, and may subsequently be initialized by a call to

#initCause

 public Error(String message) {
        super(message);
}

#initCause

Parameters:

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

 public Error(Throwable cause) {
        super(cause);
}

Constructs a new error with the specified cause and a detail message of {@code (cause==null ? null : cause.toString())} (which typically contains the class and detail message of {@code 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 #getCause() method). (A {@code null} value is permitted, and indicates that the cause is nonexistent or unknown.)

since: 1.4 -

 public Error(String message,
    Throwable cause) {
        super(message, cause);
}

Note that the detail message associated with {@code cause} is not automatically incorporated in this error's detail message.

Parameters:

message - the detail message (which is saved for later retrieval by the #getMessage() method).

cause - the cause (which is saved for later retrieval by the #getCause() method). (A {@code 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) {
        super(message, cause, enableSuppression, 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 {@code 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
