4. Write a program that prompts the user for a password that starts with a capital letter and ends with a digit. You can assume that the password entered by the user will not contain any whitespace. After the user enters a password, display a message indicating whether the user was successful or the reason the user was not successful. Save the file as ValidatePassword.java. You must use the Character class for this assignment. Examples of program execution: $ java ValidatePassword Enter your password, which must be at least 8 characters, start with a capital letter, and end with a digit: pw2New Your password (pw2New) is invalid because it: - has fewer than eight characters - does not start with a capital letter does not end with a digit $ java ValidatePassword Enter your password, which must be at least 8 characters and start with a capital letter and end with a digit: pw2 Your password (pw2) is invalid because it: - has fewer than eight characters - does not start with a capital letter $ java ValidatePassword Enter your password, which must be at least 8 characters, start with a capital letter, and end with a digit: password2 Your password (password) is invalid because it: does not start with a capital letter $ java ValidatePassword Enter your password, which must be at least 8 characters, start with a capital letter, and end with a digit: Password2 Your password (Password) is valid
