Question

Implement a prograProper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letterm that reads in a user password and verifies it meets the following criteria:

Is atleast 8 characters long
Contains atleast 1 lower letter character
Contains atleast 1 upper letter character
Contains atleast 1 numeric digit
Contains atleast 1 special character from the set: !@#$%^&*
Does not contain the word “and” or the word “end”
Output a string that prompts the user for a password and include the requirements above in your output.

Output a string that states valid or invalid. If invalid, state which rule above has not been met.

Utilize the following functionality:

· indexOf

· Looping structure

· charAt()

· isDigit()

· isUpperCase()

· isLowerCase()

· and any additional functionality needed
