    Default static variable in an instance method?

    public class Password {
     
        private static String[] passwords;
     
        public Password() {
     
            passwords = new String[] {"123", "ABC"};
        }
     
        public boolean isPasswordAuthentic(String password) {
     
            boolean isAuthentic = false;
     
            for (int x = 0; x <= passwords.length - 1; x++) {
     
                if (password.equals(passwords[x])) {
     
                    isAuthentic = true;
                    break;
                }
            }
     
            return isAuthentic;
        }
     
    }

    Can or can't?

    You should be able to. Static variables can be accessed from anywhere (following the rules of public, private, and protected of course), and anywhere includes inside of a non-static method.

    Think of static as another "object" that's created at run time that only contains static fields and static methods. It's referenced using the Class name.
