All Implemented Interfaces:

Serializable

public exception Exception
extends Throwable

The class Exception and its subclasses are a form of Throwable that indicates conditions that a reasonable application might want to catch.

Exception

public Exception()

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

Exception

public Exception(String message)

Constructs a new exception with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to {@link #initCause}.

Parameters:

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

Exception

public Exception(String message,
                 Throwable cause)

Constructs a new exception with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated in this exception's detail message.

Parameters:

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

cause - the cause (which is saved for later retrieval by the {@link #getCause()} method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Exception

public Exception(Throwable cause)

Constructs a new exception 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 exceptions that are little more than wrappers for other throwables (for example, {@link java.security.PrivilegedActionException}).

Parameters:

cause - the cause (which is saved for later retrieval by the {@link #getCause()} method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
