Question
(Creating Custom Exception Class) Write a Password class that stores a password string. Passwords must contain at least seven alpha-numeric characters, with at least one letter and one digit. Also write an InvalidPasswordException class that extends Exception. The Password constructor should throw an InvalidPasswordException, which should report an appropriate message based on a given string (e.g. if the string contains no digits, the exception should report this fact).
Use java swing to write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Some sample screenshots are shown below:
