Thread: New guy having problems with for loops, methods and charAt

Hello,
I'm new to programming and am having a problem with my homework assignment. Some parts will work but I can't figure out how I've used some loops, methods and such incorrectly. The for loop and the if statements that contain matches are not working and I am at a loss as to why. Any help would be greatly appreciated!

import java.util.Scanner;
 
public class PasswordVerifier 
{
 
	public static void main(String[] args) 
	{
		Scanner stdIn = new Scanner(System.in);
		String newPassword;		//user input
 
		boolean legalPassword = true;	// is the user input legal?
		boolean rightLength = true;		//determines correct length
        boolean uCase = true;			// Has upper case
        boolean lCase = true;			// has lower case
        boolean sCase = true;			// has special character
        boolean digit = true;			// has a number
        boolean noContainCase = true;	// doesn't have and or end
 
//newPassword print statement
 
		System.out.print("Password Verifier\n");
		System.out.print("\nEnter a password that meets the following rules: \n\n" +
		"\tIs at least 8 characters long\n" +
		"\tContains at least 1 upper case letter\n" +
		"\tContains at least 1 lower case letter\n" +
		"\tContains at least 1 numeric digit\n" +
		"\tContains at least 1 of the following: !@#$%^&*\n" +
		"\tDoes not contain the words \"and\" or \"end\"\n" );
		newPassword = stdIn.nextLine();	// user input
 
// newPassword conditions
 
		if (newPassword.length() < 8)	
		{
			rightLength = false; 
			legalPassword = false;
		}
 
		for (int i = 0; i < newPassword.length(); i++)
		{
			if (!(Character.isUpperCase(newPassword.charAt(i))));
				{
					uCase = false;
					legalPassword = false;
					i++;
				}
			if (!(Character.isLowerCase(newPassword.charAt(i))));
				{
					lCase = false;
					legalPassword = false;
					i++;
				}
			if (!(Character.isDigit(newPassword.charAt(i))));
				{
					digit = false;
					legalPassword = false;
					i++;
				}
		}
 
		String specialCh = "(.*!,@,#,$,%,^,&,*.*)";
		if (!(newPassword.matches(specialCh)))
		{
			sCase = false;
			legalPassword = false;
		}
 
		String noContain = "(.*and, end.*)";
		if (!(newPassword.matches(noContain)))
		{
			noContainCase = false;
			legalPassword = false;
		}
 
		if (legalPassword)
		{
				System.out.print("Valid");
		}
 
		else if (legalPassword != true)
		{
			System.out.print("Invalid\n");
		}
 
// Print statements		
		if (rightLength != true)
		{
			System.out.print("Password must be at least 8 characters long\n");
		}
 
		if (uCase != true)
		{
			System.out.print("Must contain an upper case letter\n");
		}
 
		if (lCase != true)
		{
			System.out.print("Must contain a lower case letter\n");
		}
 
		if (digit != true)
		{
			System.out.print("Must contain a digit\n");
		}
 
		if (sCase != true)
		{
			System.out.print("Must contain a special character from the list\n");
		}
 
		if (noContainCase != true)
		{
			System.out.print("Must not contain \"and\" or \"end\"");
		}
	}
}

What does "are not working" mean?
If there is an error message, copy-paste it to the forum

I don't get an error code. This is what prints when I make an input such as paswrd1. It doesn't matter what it contains as far as the special character, lower case, upper case, etc. The only time I can get the valid password response is if it is longer than 8 characters. Otherwise I get not response either for valid or invalid.

Password Verifier

Enter a password that meets the following rules:

Is at least 8 characters long
Contains at least 1 upper case letter
Contains at least 1 lower case letter
Contains at least 1 numeric digit
Contains at least 1 of the following: !@#$%^&*
Does not contain the words "and" or "end"
paswrd1
Invalid
Password must be at least 8 characters long
Must contain an upper case letter
Must contain a lower case letter
Must contain a digit
Must contain a special character from the list
Must not contain "and" or "end"

Thank you. I am working on doing that right now.
