having some difficulty with this problem please help. This is a (Java programming 1 only) project I'm currently working on.

Create a program that will prompt the user to enter a valid password. Valid passwords must contain at least 8 characters but no more than 12 characters. Valid passwords must not contain the upper or lower case characters a, e, i, o or u (vowels). If the password is not valid tell the user what the problem is and exit the program. If the password is valid prompt the user to re-enter their password. If the passwords match print a congratulatory message. If the passwords do not match print an error message.
