It worked thanks a lot.

Just for you info, when you create a class and don't mention any constructors, the compiler creates a default constructor for you.

Something like,

Access_modifier Classname(){ }

//which in you case is,
public Building() { }

But, when you mention any custom constructors with various parameters, the compiler doesn't do that favor to you. So whenever you have custom constructors and you still need to use the default one, then you would have to write it on your own.

Hope that makes some sense,
