Write a program with a method called passwordCheck to return if the string is a valid password. The method should have the signature shown in the starter code.

The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean return value from the passwordCheck method.

Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a character that isn’t in one of those Strings, then it’s an illegitimate password!

import java.util.Scanner;

public class JavaApplication46 {

   public static boolean passwordCheck(String pass){

       String alphanum = "abcdefghijklmnopqrstuvwxyz1234567890";

       boolean legit = true;

       if (pass.length()>= 8){

           for(int i = 0; i < pass.length(); i++){

               if (alphanum.indexOf(pass.charAt(i)) != -1 && legit != false){

                   legit = true;

               }

               else{

                   legit = false;

               }

           }

       }

       else{

           legit = false;

       }

       

           return legit;

   }

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.print("Enter a password: ");

       String password = scan.next();

       System.out.println(passwordCheck(password));

   }

   

}

I hope this helps!
