You have to match a method signature:
public boolean add(Object o)
or
public void add(int index, Object element)

try this:
exits.add( "north" );
exits.add( "west" );

By the way,what are you doing with the formal parameter "theExits"?

the add method takes 1 parameter (well, there are versions that take ore than one, but none that takes two strings....)

What you need to do is break up the adding of things into the list into two separate commands:


Also, I would just declare the exits to be a List; this hids that fact that it is an array list and lets you replace it with any type of list later one (like a LinkedList). Not that that is likely to happen here, but it is a good habit to get into.
