I am trying to create a small code that asks for a password and then once it's correct. It says "Correct".

If it's not correct then have it say "Incorrect". This is my code

String password = console.readLine("Enter Password: \n");

String answer = "Hello";

if (password == answer) {
  console.printf("Correct");
}
else { 
  console.printf("Incorrect!");
}

I would try something like:

import java.io.Console;

public class password {

    public static void main(String[] args) {
      Console console = System.console();

      String password = console.readLine("Enter Password: ");

      String answer = "Hello";

      if (password.equals(answer)) {
        console.printf("Correct. \n");
        System.exit(0);
      } else {
        console.printf("Sorry, incorrect. \n");
        System.exit(0);
      }
    }

}

Remember that in Java == tests for reference equality, where .equals() tests for value equality. Consequently, if you actually want to test whether two strings have the same value you should use .equals() (except in a few situations where you can guarantee that two strings with the same value will be represented by the same object eg: String interning). == is for testing whether two strings are the same object.

Hope it helps and happy coding,
