Quick Java Question

[CarlMartin10]

ok, I just re-read the lesson in the book, and it had more requirements for this program, so now I had to change a lot. I am stuck now. The program does not work perfectly yet.


NOTE: As it is now, I wrote it just to test that the code written so far works, I will add the rest of the required code after I know this works fine.


Program Requirements:

Main Method
-Sets up a string variable
-Calls the getPassword method
-Prints out the password string to demonstrate it was required properly

getPassword() Method
- Loop unitl a good password is entered TWICE
- Calls the isGoodPassowrd() method to determine that the password met its requirements within that method

isGoodPassword() Method
-Accepts a String and returns a Boolean


CODE:

import java.util.Scanner;

// Create Password Class
public class Password
{

	// Create main method
	public static void main(String[] args)
	{
		// Declare variables
		Scanner sc = new Scanner(System.in);
		String password = sc.nextLine();
		
		
		// Call isGoodPassword() method
		isGoodPassword(password);		
		
	}
	
	
	

	
	
		// Create isGoodPassword Method
	public static void isGoodPassword(String password)
	{
		// Declare variables
		int letters = 0;
		int digits = 0;
		boolean goodPassword;
		int len = password.length();  // Determines the lenght of the password		
					
		// Loop that prompts user to enter a password until one is entered that meets the criteria
		do
		{
			// Prompt user to enter a possible password
			System.out.println("Please enter a password");


			// Check to see if the password contains at least one number and one letter
			for (int i = 0; i < password.length(); ++i)
			{
				char c = password.charAt(i);
				if (Character.isLetter(c))
					++letters;
				if (Character.isDigit(c))
					++digits;
			}

			goodPassword = !(len < 6 || len > 10 || letters == 0 || digits == 0);
			// Check to see that the password is between 6 and 10 characters long, and contains 1 letter and 1 number, minimum
			// If the password meets the criteria, alert user. If not, ask user to enter a new password
			if (len < 6 || len > 10 || letters == 0 || digits == 0)
				System.out.println("Passwords must be between 6 and 10 characters in lenght, and contain at least 1 letter, and 1 number. Please try again.");
			else
				System.out.println("This is a good password. Please re-enter your password for verification.");
		}
		while (!goodPassword);


		
	}
