This is the code I have been working on for the past four days. I keep running into a problem on two of the lines. On both "`String command = console.nextLine();`" and "`if (command.equals("Play music")) {`" I get the same message. "`Null pointer access: The variable Command can only be null at this point`". I can't for the life of me figure out what is wrong with this code. Can anyone help me figure out what the problem is and how to solve it?
