Thread: Whats wrong with my code?

This code is supposed to be a password checker that adds the password to an array once it fits into the requirements which checking to see if its been added previously. If it has been added before, it tells you and doesn't add it. BUT it only does this for the first password that has been inputted. I'm pretty new to coding, so any help is greatly appreciated.

  public static void main(String[] args) {

 while(yo <= 20){{

         int digit = 0;
         int Upper = 0;

    System.out.println();
    Scanner scan = new Scanner(System.in);
    System.out.println("Enter Your Password: ");
        password = scan.nextLine();
 
 
       if (password.length() < min) {
         System.out.println("Your password is under 7 charcters");
        }else{
 
 
 
 
 
 
         char c;
 
         for (int i = 0; i < password.length(); i++) {
 
          c = password.charAt(i); 
 
          if(Character.isUpperCase(c)){
          Upper++;}

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

Unformatted code is hard to read and understand.

Please copy the contents of the console from when you execute the code that shows what you are asking about.
Add some comments to the output where the output is not what is desired.

The posted code has lost all its formatting. The correctly formatted code needs to have the code tags added to it.
I don't know how all the formatting was lots when the code tags were added. Please try again to have properly formatted code.
I have fixed it for you.

Please copy the contents of the console from when you execute the code that shows what you are asking about.
Add some comments to the output where the output is not what is desired.

How are you executing the program? What console is the output shown on? There must be a way to copy the contents of that console into the clipboard so that it can be pasted here in your post.
