    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 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.)

  • IllegalArgumentException

    public IllegalArgumentException(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 Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
