    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    Did you have any specific java programming questions?
    If you don't understand my answer, don't ignore it, ask a question.

    You shouldn't have your package declaration inside the body of a class. Also you shouldn't have it twice.

    To change things to private, just precede them with the private keyword instead of public.

    Well that statement creates two new Room objects, using a no-argument constructor. Except your Room class doesn't have a no-argument constructor. It just has the one that asks for 3 double values. You would need to pass 3 doubles. Also you declared a Scanner object but forgot to use it.
