Since "RoomUnsortedList" is not a standard class, I can't be sure, but I think your problem is here:


while ( i < list.getLength() && line != null )


since "i" starts at zero, and I'll assume "list" starts out empty, this loop condition is false the first time, and so no append() calls are ever made.
