[Bluej-discuss] Exercise 7.7 printLocation method on page 181

[Luis Moreira]

Hi Chris,
Have you had a look at code 7.6 pag 196?
Before you look at it this is how I see it:
- You create a room in Game
- You set exits
- So Room as now the exits info
- You then create a method that gets a String with all the exits
available by checking if exits i.e northExit,eastExit and so on are null
and keep on adding to the String if not.
- Now you have a String that has all the exits available, so in Game you
just need to add to the printLocationInfo() method, the line
System.out.println(currentRoom.getExitString()).
Anyway this is the way I have done it and of course there are many ways
to solve this which may be better, but it does work. 
Hope it helps
Best regards
		Luis

The printLocation method, exercise 7.7 on page 181.
I just can't seem to get my head around this.  I have made all the
changes up to this point.  Can someone please give me the full code for
this method so that i can figure out what is happening.  It is probably
something so easy staring me in the face but i just can't see it.
