Thread: please help super new to Java

I am new to Java and to be honest I am kind of lost, please help me figure out what is wrong with my code.
i have to write a code that prompts the user for a password using 6 to 10 characters using a letter.
My apologies if I am posting this in the wrong place

here is what i have so far:

import java.util.Scanner;
public class unit8
 
    {
            //main method
	public static void main (String [] args)
 
	{
	  Scanner myScanner = new Scanner (System.in);
 
	  // create string variables
	       String password, confirmpassword;
	       Boolean digit = false;
	       Boolean letter = false;
	       char testCharacter;
	       String length;
 
 
	// Prompt to use password
	       System.out.println(" Please enter a possible password");
	        password = myScanner.next();
 
	// test password
	       for(int i = 0; i<password.length(); i++)
 
 
	{
 
	        int passwordLength;
	        if (passwordLength(length <= 6 || length >= 10));
	        return false;
 
	        testCharacter = password.charAt(i);
	        if(Character.isDigit(testCharacter))
	        digit = true;
	         if(Character.isLetter(testCharacter))
	         letter = true;
	}
 
	          if (digit && letter)
 
	{
	 // Promt to enter password second time
	          System.out.println("This is a good password");
	          confirmpassword = myScanner.next();
	           if (password.equals(confirmpassword))
	           System.out.println("Your passwords match congratulations " + password);
	           else
	           System.out.println("There is an error please try again");
	}	
	           else
	           System.out.println("Your Password is incorect. Password needs one digit one letter, please try again");
 
	}
}

What's the problem with it? Does it give you error messages? If so, post up the full message text and stack trace if present. Does it do something it shouldn't or not do something it should? If so, explain what that is.

thank you for your fast reply. When ruuning the program it is supposed to ask you a password and should be between 6 to 10 characters and have a letter in it. here is my error messages.
