    I'm not sure how to do this or where to put it.

    What are you trying to do in the if statement?
     if ( s == XRay )

    Please be more specific and not use words like this and it. I can't read your mind.

    How do you define XRay, I do not know how to put that code in or where exactly to put it. I don't understand the difference between a variable and a string.

    Alright I've almost got it, all I need to do now is define XRay as the password.

        import java.util.Scanner;
     
        public class Password{
            public static void main(String[] args) {
     
          Scanner kbReader = new Scanner(System.in);
          System.out.println("Enter your password. ");
          String myPassword = kbReader.nextLine();
     
     
          if ( myPassword == "XRay" )
          System.out.println("Password entered successfully.");
     
          else
          System.out.println("Incorrect password.");
          }
        }

    if ( myPassword == "XRay" )
    New topic: comparing the contents of objects. Strings are objects. If you want to compare the contents of two objects you need to use the equals() method:
    myPassword.equals( "XRay" )
    If you don't understand my answer, don't ignore it, ask a question.
