Public Constructors

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 initCause(Throwable).

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 initCause(Throwable).

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

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 getMessage() method).
cause 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.)

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, PrivilegedActionException).

Parameters
cause 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.)
