Exceptions

Provide exception classes for the following:

$1.$ Length of password is less than $6$ characters $($class LengthException$)$

Message $$ The password must be at least $6$ characters long

$2.$ Password doesn$$t contain an uppercase alpha character $($class NoUpperAlphaException$)$

Message $$ The password must contain at least one uppercase alphabetic character

$3.$ Password doesn$$t contain a lowercase alpha character $($class NoLowerAlphaException$)$

Message $$ The password must contain at least one lowercase alphabetic character

$4.$ Password doesn$$t contain a numeric character $($class NoDigitException$)$

Message $$ The password must contain at least one digit

$5.$ Password doesn$$t contain a special character $($class NoSpecialCharacterException$)$

Message $$ The password must contain at least one special character

$6.$ Password contains more than $2$ of the same character in sequence $($class InvalidSequenceException$)$

Message $$ The password cannot contain more than two of the same character in sequence.

$7.$ Password contains $6$ to $9$ characters which are otherwise valid $($class WeakPasswordException$)$

Message $$ The password is OK but weak $-$ it contains fewer than $10$ characters.

$8.$ For GUI $$ check if Password and re$-$typed Password are identical $($class UnmatchedException$)$

Message $$ The passwords do not match

Throw this exception from the GUI, not the utility class.

Note: If more than one error is present in a password, use the above order to throw exceptions. For example, if a password is $$xxyyzzwwaa$$,$ it fails rules $2$ and $4$ above. Throw a NoUpperAlphaException, not a NoDigitException.
