(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:

Using this app, user can • add student information • view all students • search student(s) by name • remove student by id Add • First name, last name, date of birth cannot be blank while adding a specific student information. • However major can be blank, which gets set to "Undefined" if left out blank. • Student Id is automatically generated by the program (ex: 1001, 1002, 1003, 1004 ….) If the user keeps a mandatory field blank (ex: First name) and presses "Add Student" button, it displays the following message box: first name is required If the user successfully enters all the necessary information and presses the "Add Student" button, it displays the following confirmation message box: student added View All When the user presses the "View All" button, it displays all the student’s information (Id, First name, Last name, Date of birth, and Major) in a nice formatted way.
